Precipitation hardening stainless steel (17-4-PH) of 3 mm thick sheet was welded by gas tungsten arc welding (GTAW) process using a matching composition filler wire of ER 630. The welds were subjected to various post weld heat treatment (PWHT) cycles viz., H900, H1025 and H1150. Tensile properties (UTS, 0.2% YS, and % EL.), hardness survey across the weld and detailed optical microscopy have been carried-out on as-welded and after different PWHT conditions samples. Results showed that H900 heat treatment condition attained higher mechanical properties than H1025 and H1150.
