Abstract

In this investigation, a comparative study has been done to show the effect of prewelding and post-welding processes on the weld-induced distortion in a submerged arc-welded butt joint of P91 steel plate. An optimal set of welding parameters are selected beforehand for conducting the experiment to prepare single-sided and double-sided weld joints. The experiment samples were prepared for four different welding cases as with and without preheating and with and without post-welding heat treatment (PWHT). The distortion was measured for the points on the top surface of the plate. Edge deflection or say buckling distortion on both the edges and angular deformation in transverse direction of the weld line direction was measured at the start, end, and middle portions of the welded joint. The comparison of the results concludes that both preheating and post-welding heat treatment collectively influence the overall distortion pattern in the welded plate in positive direction.
