Sealed lead sour accumulator welding clamp and welding process thereof

The invention discloses a sealed lead acid battery welding fixture and a welding process; the welding fixture comprises two welding comb plates, a positive welding comb plate and a negative welding comb plate, which comprise a vacant comb plate groove, a vacant comb plate tooth, a column and a locating plate. The vacant comb plate groove is arranged on the vacant comb plate tooth. The vacant combplate is connected with the locating plate through the column. A busbar, a designed detail part and a tab seam matched with the tab of the plate are formed between the comb plate groove and the vacant comb plate tooth. The sealed lead acid battery welding fixture also comprises a locking strip. The locking strip is provided with a bayonet which is corresponding to the tab seam of the two welding comb plates. The welding process comprises plate wrapping, comb plate locking, locking strip arranging, flow welding, lead ash cutting and comb plate disassembling, battery shell setting, joint welding, soot blowing, cap checking, short circuit checking and battery assembling. The traditional processe of comb plat box setting, polar post arranging and parts butt welding, and the step of false welding checking are avoided. The production efficiency is improved.
