In Situ Detection of Thermal Cycle in Weld Metal of Cr-Mo Steel

Abstract:

With the self-designed system of welding thermal cycle test, low alloy steel of Cr-Mo series was welded through proper welding procedure according to the phenomenon of cold crack and local hardening in weld metal, and in-situ detection of thermal cycle for deposit metal was realized. The results show that self-designed system is reliable within the error range, the maximum peak temperature during thermal process was above 1700°C, it is largely improved than reported formerly.
