STEEL WELDABILITY INVESTIGATION BY SINGLE AND DOUBLE-PASS WELD THERMAL CYCLE SIMULATION

Investigation of weldability by thermal cycle simulation of welding is an accelerated testing procedure that provides quantitative indicators of weldability in the heat-affected zone of the welded joint. This paper presents the research into weldability by weld thermal cycle simulation performed in single and double passes on the Smitweld 1405 simulator. Thermal cycle simulation of welding significantly shortens the process of selecting optimal welding parameters and attesting the welding procedure, and it also reduces total costs of weldability testing. The data obtained by this weldability testing method are repeatable and verifiable, so they can be used with sufficient reliability in selection of optimal welding parameters and in attesting of welding procedures.
