Effect of Process Variables on Angular Distortion of Pulse MIG Welded HSLA Plates

Abstract

Angular distortion is a major problem and most pronounced amongst different types of distortion in the butt welded plates. It is difficult to obtain a completely analytical solution to the problem of anguiar distortion which may be reliable over a wide range of processes, materials and procedural variables. In this study, the statistical method of 2 level full factorial technique has been used to aevelop models which correlate angular distortion with Pulse MIG process variables and joint parameters.
