Use intermittent / staggered welding Minimize the number of weld passes Plan and Weld, on/about the neutral axis Use balance welding, like back-step/skip weld/scatter weld technique Pre-set parts to counter distortion Clamp/restrain the object from moving during welding Use Restoration Methods(Thermal Tensioning, PWHT), to correct distortion Prediction ofWelding Distortion A two-stepnumerical analysis technique was developed to predict welding induced distortion and the structural integrity oflarge andcomplex structures ABSTRACT. The tech nique combines two-dimensionalweld See full list on repository. Figure 12. One of the ways to control or reduce the welding distortions is the manipulation of the generated stresses during welding, and final residual stresses exist in the workpiece (stress engineering). In this paper, the control of gas metal arc butt welding distortion. This paper presents a nu merical analysis technique for predicting welding-induceddistortion. ntoxdqsmsanaafmafsqshyzcboszoiwlocckzvqmojqc
