Welding sequence optimization of plasma arc for welded thin structures [PDF]
WIT Transactions on The Built Environment, 2012 Dividing the weld path into multiple seams that are welded sequentially in a specific order is one of the most important and cost effective distortion and residual stresses mitigation strategies. This is particularly important for welding fabrication of thin structures.
