Abstract: One of the major disadvantages of many arc welding processes is that the welding-induced distortions in a welded structure is the result of the non-uniform expansion and contraction of the weld and surrounding base material caused by the heating and cooling cycle during the welding process many factors in the welding procedure contribute to the distortion these factors arc very difficult to manage in large complex structures, these include the welding sequence degree of restraining welding conditions and joint details at present but there is no process that completely eliminates the distortion of many distortion control techniques and the welding design Optimization procedures such as thermal tensioning heat sink welding and weld sequencing are developed by experiment and experience.
