In order to save resources, reduce production costs and meet the needs of different users without reducing the corrosion resistance of stainless steel, it has a wide range of applications and has better mechanical and processing properties, so it has more With good economic and social benefits, stainless steel composite plates are a new industrial product. The stainless steel clad plate is a bimetal clad plate made of carbon steel or high-strength steel as the base layer, stainless steel as the cladding layer, and made by rolling, surfacing, explosion, and other methods. Generally, the strength of the composite board is guaranteed by the base layer, and the corrosion resistance of the composite board is guaranteed by the cladding layer. It not only has the durability, formability, corrosion resistance, and other excellent properties of stainless steel, but also has the advantages of high strength and low cost of carbon steel, so it is widely used in petroleum, chemical, pharmaceutical, pipeline, and other fields.
Welding is one of the most important processes in the manufacture of stainless steel composite equipment. The quality of the weld seam is directly related to the corrosion resistance and the service life of the equipment.
For the mixture of dissimilar steels in the transition layer, if the welding consumables are not selected properly or the welding process is not appropriate, the stainless steel weld may be severely diluted to form a martensitic hardened structure, or the pearlite may be strongly involved according to the chromium and nickel elements. The body steel layer is severely embrittled and cracked.
The carbon diffusion process occurs at high temperatures in the transition zone, and as a result, a high-hardness carburization zone and a low-hardness decarburization zone are formed at the junction, making the transition zone.
