Welding skills of stainless steel composite steel plate

Overview of stainless steel clad plate

Steel plate is a bimetal plate made of thicker pearlite steel (base) and thinner stainless steel (multilayer). The substrate is mainly carbon steel and low alloy steel, such as Q235, 20, 20g, 20R, 09Mn2, 15MnTi, 16Mn, 16MnR, 14Cr1MoR, 15CrMoRH, etc. The cladding is mostly stainless steel with good corrosion resistance, such as 1Cr18Ni9Ti, 0Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 0Cr18Ni12Mo2Ti, 1Cr18Ni9, 0Cr13, Cr23Ni28Mo3Cu3Ti, etc.

The welding at the junction of the base layer and the cladding layer of the stainless steel clad plate is dissimilar to steel welding. Its weldability mainly depends on the physical properties, chemical properties, joint form and filler metal type of the cladding and base layers. It often produces high-temperature crystallization cracks, delayed cracks and Embrittlement problems. Welding methods include electrode arc welding, submerged arc welding, CO2 gas shielded welding, etc. At present, argon arc welding is commonly used to weld the cladding and electrode arc welding is used to weld the base layer. In order to ensure that the steel clad plate does not lose its original comprehensive performance, the base layer and the cladding layer must be welded separately; the welding process of the base layer is the same as that of pearlite, the welding process of the cladding layer is similar to that of the corresponding stainless steel, and the dissimilarity at the junction of the base layer and the cladding layer is Metal welding is key.

Preparation before welding

1. Mechanical shearing and cold stamping processing are used When cutting stainless steel clad plates, generally when the total thickness is less than 12mm. During processing, the cladding layer must be downwards and upwards from the base layer, and the surface and joints of the cladding layers must not be damaged. When the layers are thick, plasma cutting (starting from the cladding side) and oxygen-acetylene flame cutting (starting from the base side) can be used. (The oxygen pressure and cutting speed are smaller than those of carbon steel plates of the same thickness, but the cutting nozzle is slightly bigger.)

2. For stainless steel forming, cold bending at room temperature should be carried out as much as possible. Sharp bending should not be performed on a rolling machine or press. It should be processed slowly step by step. If hot processing is required, the surface of the workpiece must first be cleaned of oil and impurities. Use weakly oxidizing hot workpieces to prevent carburization; the low-carbon steel substrate can be air-cooled, and the low-alloy steel substrate must be thermally insulated and slowly cooled. The heating temperature is 700~850℃.

3. Bevel production. When making bevels, thin parts can usually use I-shaped grooves, and thicker parts can use V-shaped, U-shaped, X-shaped, V-shaped and U-shaped combined grooves. Generally, X-shaped groove double-sided welding is used as much as possible. The base layer is welded first, then the transition layer is welded, and finally the cladding layer is welded to ensure that the welded joint has better corrosion resistance. When the welding position is limited and only single-sided welding can be used, a V-shaped groove can be used to weld the cladding layer first, then the transition layer, and finally the base layer. During welding, try to prevent the base layer from being melted into the cladding layer.

4. Selection of welding materials for stainless steel clad plates. When the thickness of the clad plate is less than 25mm, the base layer can also use A302 electrodes (higher stress); when the clad plate is larger than 25mm, a transition layer can be welded with pure iron electrodes first. Then, use steel welding rods to weld the base layer. Commonly used welding materials are selected as shown below:

Welding operation

1. The welding sequence of stainless steel composite steel is generally: first weld the base layer, then weld the transition layer, and finally weld the cladding layer to ensure that the welded joint has good corrosion resistance. At the same time, the welding characteristics of the transition layer should also be considered to minimize the cladding layer. Amount of welding work on one side.

2. Regardless of whether the cladding layer is inside or outside the corner joint, the base layer must be welded first. When the cladding is located on the inside, the base layer welding roots should be cleaned from the inner corner before welding the cladding; when the cladding is on the outside, the last weld pass of the base layer should be polished. When welding the cladding, the transition layer can be welded first or directly welding the cladding depending on the thickness of the stainless steel clad plate.

3. Since the carbon diffusion process occurs in the transition layer at high temperatures, a high-hardness carbonization zone and a low-hardness decarburization zone are formed in the junction area, making the transition layer form a complex metallographic structure and increasing the difficulty of welding. Therefore, in order to prevent the first layer of base weld from melting into austenite, part of the clad metal near the joint can be processed in advance.

4. Weld the base layer first. The first base layer weld should not penetrate into the cladding layer to prevent the weld metal from embrittlement or cracking. When welding the base layer steel, the conventional welding current for the base layer should still be used. After the base layer is welded, use carbon arc gouging, shoveling, grinding and other methods to clean the welding root. If the requirements are high, the transition layer can only be welded after passing X-ray flaw detection.

5. Transition layer welding, in order to reduce the dilution rate of the base metal to the weld, the welding current should be as small as possible while ensuring penetration; to use small diameter welding rods and narrow weld beads, the base weld must be covered and cut higher than The base layer is 1mm, and the welding seam must be smooth and not convex. Otherwise, it must be polished off.

stainless steel 

6. When welding small-diameter stainless steel composite steel pipes, the first layer of welding should be tungsten arc welding, and the second layer can be welded with austenitic stainless steel electrodes.

7. For high-pressure vessels made of large-thickness stainless steel clad plates, the internal stainless steel composite layer is welded first during the welding process. A ferrite transition layer is welded, and finally the base weld is filled with low-alloy steel electrodes.

8. When selecting structural materials according to working conditions, the diffusion layer in the fusion zone of austenitic weld and pearlitic steel should be reduced to a minimum. This

It is especially important for components working in high temperature and corrosive media and large components that need to be tempered after welding.

9. During operation, attention should be paid to protecting the cladding surface of non-welded parts to prevent arc scratches. The base weld should leave a suitable depth for the transition layer, which is generally about 2mm away from the cladding.

Post-weld treatment

For welded joints of stainless steel composite steel, neither solid solution nor stress relief treatment is generally performed on the cladding. However, intermediate annealing and stress relief treatment are often used for extremely thick weldments. The heat treatment to eliminate residual stress is best carried out after the base layer is welded. After the heat treatment, the transition layer and cladding layer are welded. If the overall heat treatment is required, the temperature should be selected. Considering the impact on the corrosion resistance of the cladding, the unevenness of the transition layer and the differences in physical properties of dissimilar steels, the temperature is generally 450~650℃.

Common post-weld treatment methods for stainless steel composite steel include annealing, shot peening, and stress relief using deformation methods.

Which is the best way to backfill a bathroom

The backfilling of the bathroom is a crucial part of any renovation. Backfilling is an essential part of bathroom renovations. It is used to stop leaks, protect the pipe, and increase the thermal insulation. In selecting bathroom materials, you should consider several factors depending on your specific situation. For example, take into account the performance and cost of backfill material as well the environmental protection.

There are five types of backfills available on the market: common slags, carbon-slags backfills (also known as carbon slag), ceramics backfills and foam cements backfills. There's some confusion over different backfills.

Backfilling with slag can be cheaper, but because it is heavy and can cause the slab to crack easily, this could lead to leaks.

It is cheaper to use overhead backfill because you don't need as much material.

Since a few decades, foam cement backfilling has been popular. But does it come with any disadvantages?

For your information, here are five bathroom backfill materials with their advantages and disadvantages and some selection advice:

Building debris backfill

Advantages:

The advantages of slag backfill are its lower cost, ease of construction and certain thermal insulation properties.

Disadvantages:

Backfilling with construction waste will damage the waterproofing or the pipeline due to its sharp edges.

Recommendation:

Has been eliminated. This is not a method that should be used. It will cost too much for the family to backfill with construction debris. To protect the waterproofing of the ground, first use fine sand, then red brick to shield the pipeline. The backfill should be compacted in layers. Finally, mud-mortar to level the surface will provide good secondary drainage.

Carbon Dregs Backfill

Advantages:

Carbon slag as a backfill has many advantages, including its low cost, ease of construction, lightweight structure, good moisture absorption, and excellent moisture control.

Disadvantages:

Carbon dregs are not as stable, they can easily deform or fall off and are relatively flimsy. They also absorb moisture, so the volume will increase, increasing the pressure of the floor slab.

Recommendation:

In recent years, carbon slag has rarely been chosen as a backfill in bathrooms due to its negatives.

Ceramic Backfill

Advantages:

Ceramic backfill has many advantages including high strength, good insulation and corrosion resistance.

Disadvantages:

Before pouring in the ceramic, use lightweight bricks for layered partition. Divide the bathroom into several squares. Fill the squares with the ceramic, then place a reinforcing mesh with a diameter around one centimetre. Finally, level with cement mortar.

Suggestion: Look at your family's budget and take it into consideration.

Overhead Backfill

Advantages:

Backfilling with overhead backfill has many advantages, including its simplicity, stability, inability to deform and easy fall-off.

Disadvantages:

The labour cost of backfilling is higher because the construction cycle is longer. The sound of running water is louder when the bottom drain is located overhead.

It is important to carefully consider whether the disadvantages of the situation outweigh any advantages.

Foamed Cement Backfill

Advantages:

Foamed cement is an increasingly popular backfill. It is also safe and eco-friendly. The raw material for cement foaming agents, plant-based fat acid, is both safe and environmentally friendly.

Benefits include good heat conservation, light weight, high strength and corrosion resistance. The backfilling process is greatly accelerated and reduced in cost, as it can be filled seamlessly and with very little effort.

Foamed cement can be mixed with cement and used to fix the pipe. If not, the pipe will easily float.

Disadvantages:

It is best to find a builder that has worked with foam cement or look up construction tutorials.

Suggestion:

The majority of people backfill their bathrooms with foamed-cement. Its advantages are still quite obvious.

The five types of backfill for bathrooms all have advantages and disadvantages. In order to choose the best material for your bathroom backfill, you should consider a number of factors. You must always consider the environment when choosing bathroom backfill materials to ensure the decor of the bathroom is safe and sustainable.

What is Lithium stearate powder

Lithium stearate is a crystalline form of lithium.

Lithium stearate has the chemical formula LiSt. It is a white powder that is solid at room temperatures. It is highly lipophilic, and at low concentrations can produce high light transmission. This compound is soluble only slightly in water and is readily soluble when heated to room temperature in organic solvents, such as acetone and ethanol. Lithium Stearate is stable and thermally safe at high temperatures because it has a melting and flash point. The lithium stearate also has good chemical resistance and is resistant to acids and bases, as well as oxidants, reductants and reducing agents. Lithium is less toxic than other metals, but should still be handled with care. An excessive intake of lithium can lead to diarrhoea or vomiting as well as difficulty breathing. Wearing gloves and goggles during operation is recommended because prolonged exposure to lithium can cause eye and skin irritation.

Lithium stearate:

Surfactant: Lithium Stearate Surfactant, lubricant, and other ingredients are used to make personal care products, such as shampoos, soaps, body washes, and cosmetics. It has excellent foam properties and good hydrolysis stabilty, resulting in a gentle and clean washing experience.

Lithium stearate has an important role to play in polymer syntheses. It can be used both as a donor and a participant in the formation of polymer chains. These polymers have good mechanical and chemical properties, making them ideal for plastics, rubber fibers, etc.

Lithium stearate can be used in cosmetic formulations to soften and moisturize the skin. It enhances moisturization, and makes the skin softer and smoother. The antibacterial and antiinflammatory properties of lithium stearate can also help with skin problems.

Paints & Coatings: Lithium is stearate can be used to thicken and level paints & coatings. It helps control the flow a coating and its properties. It is resistant to weather and scratches, which makes the coating durable.

Applications of lithium stearate include drug carriers, excipients, and stabilizers. It can enhance the taste and solubility and stability of medications.

Agriculture: Lithium isostearate may be used to carry fertilizers and as a plant-protection agent. It increases the efficiency of fertilizers and improves plant disease resistance.

Petrochemicals: In the petrochemicals, lithium stearate acts as a lubricant or release agent. As a catalyst in petroleum cracking, lithium stearate improves cracking yield and efficiency.

Lithium Stearate Production Process :

Chemical Synthesis:

Lithium stearate can be synthesized through a series a chemical reactions. In order to get the two reacting fully, lithium metal is heated and stearate root is stirred together in an organic solvant. After washing and drying, the pure lithium-stearate product is obtained.

Following are the steps for synthesis.

(1) Lithium metal and stearate in organic solvents, such as ethanol heated stirring to fully react.

(2) The reaction solution must be cooled in order to precipitate lithium stearate.

(3) Wash the crystal with water and remove any lithium stearate particles.

(4) The dried crystals will be used to make lithium stearate.

The benefits of chemical synthesis include a matured process, high production efficiency, and high product quality. However, organic solvents have an environmental impact and waste is generated during production.

Methode de fermentation biologique

In biological fermentation, microorganisms such as yeast are used in the medium to produce lithium. The principle behind this method is that microorganisms use their metabolic pathways to produce stearic and react with metal ions, such as lithium, to create lithium stearate.

These are the steps that you will need to take in order to produce your product.

(1) The microorganisms will be inoculated onto the medium that contains precursor substances for fermentation cultures;

(2) The filtrate is used to produce a solution of stearic acetic acid.

Add metals (such as the lithium ions) into the solution with stearic to ensure that they fully react.

(4) The reaction product is separated and washed, then dried to give lithium stearate.

The benefits of biological fermentation include environmental protection, less waste discharge and a longer production process. However, the conditions for production are also higher.

Prospect Market of Lithium Stearate:

The application of lithium in personal care will continue to be important. It plays an important part in cosmetics, soaps, and shampoos as it is a surfactant. As people's standards of living improve and the cosmetics sector continues to expand, lithium stearate demand will gradually rise.

Second, the use of lithium stearate for polymer synthesis has also increased. It can be used both as a donor and a participant in polymer chain formation. As polymer materials science continues to develop, the demand of lithium stearate increases.

Lithium stearate's application in agricultural, petrochemical, pharmaceutical and other fields is also growing. In the pharmaceutical sector, lithium stearate may be used as a carrier, excipient or drug stabilizer. In agriculture, the lithium stearate is used to protect plants and as a carrier for fertilizer. In the field of petrochemistry, lithium isostearate may be used as an lubricant or release agent. In these areas, the demand for lithium will increase as technology advances.

But the outlook for the lithium stearate market is not without its own challenges. In order to produce lithium metal, it is necessary to use a more expensive production process. Aside from that, the applications of lithium is limited, with a concentration in agriculture, pharmaceuticals and petrochemicals. To expand the scope of application and the demand for lithium stearate, it is important to continue to develop new applications and markets.

More than a hundred schools in the UK have been closed due to the risk of collapse

In the UK, more than 100 schools were closed because of the danger of collapse

In the UK, many schools use Autoclaved aerated cement (RAAC). This is a concrete material that is lighter.

In 2018, the roof of a school in southeast England collapsed. It was later discovered that RAAC had been used for the roof as well as the buildings. This raised safety concerns.

BBC reported that RAAC materials were widely used from the 1950s until the mid-1990s in areas such as roof panels, and had a lifespan of around 30 years.

According to reports, the risk of building collapse is not limited only to schools, but also courts, hospitals and police stations. RAAC material has been found.

The Royal Dengate Theatre at Northampton is temporarily closed after RAAC material was found.

According to NHS, RAAC has been detected in 27 hospital building.

The NHS chief has been asked for measures to be taken to prevent collapse.

BBC reported that since 2018 the British government has warned schools to be "fully ready" in case RAAC is found within public buildings.

The Independent reported Jonathan Slater a former senior education official, who said that Sunak, Prime Minister in 2021, approved budget reductions to build schools.

Nick Gibb is a senior official at the Department of Education. He said that the Department of Education asked for PS200m annually for school maintenance. Sunak, then the chancellor, only provided PS50 million per year.

The report also states that despite Sunak having promised to renovate at least 50 schools every year, in the main reconstruction plan of the government only four schools were renovated.

The British National Audit Office chief also condemned the crisis. Sunak's government, he said, had adopted a "plaster-method" of building maintenance.

He believes the government's underinvestment has forced schools to close, and that families are now "paying the cost".

Paul Whitman is the secretary-general of National Association of Principals. He said that the public and parents would perceive any attempt to blame individual schools on the government as "a desperate move by the federal government to divert its attention from their own major errors."

Whitman claimed that the classroom has become completely unusable. Whitman blamed the British Government for the situation. "No matter what you do to divert or distract, it won't work."

London Mayor Sadiq khan said that the government should be open and transparent. This will reassure parents, staff, children, and others.

BBC reported schools in the UK were pushing forward with inspections and assessments. Children who had been suspended because of school building issues will be temporarily housed, or they can learn online.
