Intelligent backing welding method, backing welding control system and welding assembly

The invention relates to the field of welding, and discloses a backing weld intelligent welding method, a backing weld control system and a welding assembly.The backing weld intelligent welding method comprises the steps that the gap width of a to-be-welded position is detected; and under the condition that the width of the gap is larger than the preset critical value, the welding gun equipment is continuously and repeatedly switched between the arcing state and the arc quenching state, and the welding wire is made to vibrate. According to the automatic backing welding technical scheme, labor can be saved through automatic backing welding, the quality of welding seams is improved, meanwhile, large-gap and backing-free backing welding forming and efficiency are effectively considered, and the welding operation adaptability to to-be-welded workpieces with different structural sizes and shapes and different application scenes is improved. 本申请涉及焊接领域，公开了一种打底焊智能焊接方法、打底焊控制系统和焊接总成，其中，打底焊智能焊接方法，包括：检测待焊接位置的间隙宽度；在间隙宽度大于
