Abstract

The objective of the present investigation was to measure the mechanical properties of dissimilar weld joints of copper to stainless steel 304, fabricated using Tungsten inert gas (TIG) welding process. As-welded specimens were heat treated to a temperature of 650 °C for 1h, 2h and 3h. Tensile strength and microhardness measurements were made to analyze the effect of post weld heat treatment on the mechanical properties of dissimilar weld joints of copper and stainless steel. Specimens heat treated at 3h showed increase tensile strength and hardness, when compared to the specimen’s heat treated at 1h and 2h.

Keywords: TIG welding; Heat treatment; Hardness; Tensile strength; Mechanical properties

Abbreviations: GMAW: Gas Metal Arc Welding; GTAW: Gas Tungsten Arc Welding; SAW: Submerged Arc Welding; TIG: Tungsten Inert Gas
