Configuration of and welding procedures applied to cruet shaped bevels in objects to be welded

摘要

Metallic objects such as steel pipes and shipbuilding plates are welded using complemental bevels in the faces to be welded which, when abutted, define a channel of cruet shaped cross-section. The cruet shaped channel allows the filling weld passes to be performed using a welding instrument oscillated only at tolerance amplitudes in a range of 1.5 mm±0.5 mm rather than bevel width amplitudes. The process can be used in single or double side welding applications.
