Abstract

In this investigation, the effect of post heat treatment on the microstructure and mechanical properties of IS2062 steel are analyzed. Similar metal joints of IS2062 weldments are prepared by using MIG (Metal Inert Gas) welding process. This melting is occurring at the edges of the plates because, sufficient amount of heat energy is passing over the plate per unit time and density of energy is supplied to the wire. In this connection of heating and cooling of weldment, some disturbances occur in metallurgical and mechanical point of view. To overcome this, a suitable PWHT (Post Weld Heat Treatment) is applied to avoid the disturbances and improve the mechanical and microstuctre of the weldment. The objective is to determine the optimum PWHT method for the IS2062 steel. After welding, the effects of PWHT on weld metal microstructure and mechanical properties including weldment tensile strength, impact and hardness over the room temperature range of 32^oC are investigated. In particular, the effect of these treatments on the Tensile strength, Impact, Hardness of the materials and weldments before heat treatment and after PWHT are studied.
