The toughness of weld metal is the highest while the coarse grained region in the HAZ is the lowest because of weldingthermalcycle and formation of brittle microstructure.
The weldingthermalcycle and section dimensions of the welding seam were measured in the condition of the simulated welding process parameters for checking simulation results.
A new type of computer-aided testing and analyzing system for weldingthermalcycle is presented in this paper. The system adopts computer technology and data processing methods.
