Regressive models of mechanical properties of multi-layered welded joints from 30XгCA steel

摘要

Effect of the controlled thermal welding cycle parameters (current, temperatures of preheating and after welding heat treatment) on mechanical properties of multi-layered welded joints from 30XгCA steel is considered and regressive linear relationships are obtained. It's stated that preheating temperature has no significant influence on mechanical multi-layered welded joints form steels like 30XгCA one. Resource-saving technology for multi-layered welded joints fabrication from steels of given class is developed.
