Study of Laser Welding of HCT600X Dual Phase Steels

Švec Pavol / Hrnčiar Viliam / Schrek Alexander

The effects of beam power and welding speed on microstructure, microhardnes and tensile strength of HCT600X laser welded steel sheets were evaluated. The welding parameters influenced both the width and the microstructure of the fusion zone and heat affected zone. The welding process has no effect on tensile strength of joints which achieved the strength of base metal and all joints fractured in the base metal.
