In order to solve the problems such as complicated installation,deformation after welding,breaking when turning over,damage to the base metal and heavy manufacturing workload in the process of using the quenching arc plate in the butt weld of ships,a technological innovation was made from the perspective of reuse.By using the allowance left in steel customization,the base metal of the work-piece and the quenching arc plate were cut together during blanking,which is referred to as"integra-tion of the quenching arc plate and the base metal".The base material and the arc extinguishing plate can be integrated into a whole,so as to improve the production efficiency,ensure the welding quality and reduce the comprehensive cost.
