Abstract
Comparative investigation of hot cracking sensitivity of commercial welding wires has been performed. It is shown that an all-purpose method of weldability evaluation can be the machine method with controllable forced deformation during TIG welding (PVR-test method), which allows separating the conditions of initiation of solidification cracks and ductility dip cracks in the weld and HAZ metal, and provides comprehensive information about quantitative characteristics of cracking sensitivity. 6 Ref., 9 Figures.
