Clad plates welding process

The welding method shall be determined according to the composite steel plate material, joint thickness, groove size and welding conditions. At present, manual arc welding is commonly used to weld composite steel, and argon arc welding, submerged arc welding or gas shielded welding can also be used. In order to reduce the fusion ratio, double wires can be used

Submerged arc welding. In the actual production, the base layer is usually welded by automatic submerged arc welding, and the multiple layer and transition layer are welded by manual arc welding and argon arc welding.

In order to ensure that the composite steel plate does not lose its original comprehensive performance, the base layer and the composite layer must be welded separately. The welding process of base layer is the same as that of pearlitic steel, and the welding process of cladding is similar to that of corresponding stainless steel (or nickel base alloy, titanium and titanium alloy, etc.),Only the welding at the junction of base layer and cladding belongs to the welding of dissimilar metals.
