Application Summary AI generated
This standard specifies recommended joint preparation geometries for welding clad steels, detailing groove angles, root faces, and gap dimensions to ensure proper fusion and minimize dilution between the base metal and cladding layer. It is applied in manufacturing industries such as pressure vessel fabrication, chemical equipment, and shipbuilding, where clad steels (e.g., stainless steel or nickel alloy on carbon steel) are welded to maintain corrosion resistance and mechanical integrity. The standard guides welding engineers and inspectors in preparing joints for manual, automatic, or semi-automatic welding processes.
