investigating the effect of welding sequence on angular distortions in butt welded plates

one major disadvantage of many arc welding processes is welding -induced distortions 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 welding process many factors in the welding procedure contribute to the distortion these factors arc quite difficult to manage in large complex structures these include welding sequence degree of restraint welding conditions and joint details at present however there is no process that completely eliminates distortion many distortion control techniques and weld design optimization procedures such as thermal tensioning heat sink welding and weld sequencing are developed by experiment and experience.
