Abstract EN
The effect of postweld heat treatment (PWHT) on the carbon migration and mechanical properties of the 2205DSS-Q235 laser beam welding (LBW) joint was investigated.
The carbon-rich zone (CRZ) and carbon-depleted zone (CDZ) generated at the welding seam/Q235 (WS-Q235) interface as the carbon migration occurred after heat-treated at 600°C, 700°C, and 800°C for 1 h.
The softening was found in the CDZ.
Only the CRZ in joints heat-treated at 800°C was hardened because of the retaining of high-carbon untempered martensite.
The thick CDZ in joints heat-treated at 700°C and 800°C contributed to the tensile fracture and the low elongation.
The strength of the joint was roughly determined by the hardness of the fracture zone.
