The invention discloses a frame welding method. The frame welding method comprises the following steps that a bottom plate, an inner ring vertical plate and middle rib plates are welded to form a first welding assembly; a cover plate is welded with the first welding assembly to form a second welding assembly; peripheral vertical plates are welded to the second welding assembly one by one, and a third welding assembly is formed; and a peripheral sealing plate is welded to the third welding assembly, and a multi-cavity welding frame is formed; wherein the middle rib plates comprise a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs. The problems that in an original welding method, personnel conduct welding in a narrow closed space, movement is inconvenient, poisonous and harmful gas generated during welding cannot be diffused, and the risks of poisoning, suffocation and the like are likely to happen are solved. And meanwhile, the problem that the welding quality is difficult to control due to narrow welding space and insufficient light is solved.

    本申请公开一种车架焊接方法,包括如下步骤:焊接底板、内圈立板及中间筋板,形成第一焊接组件;将盖板与所述第一焊接组件焊接,形成第二焊接组件;将外围立板逐个焊接至所述第二焊接组件上,形成第三焊接组件;将外围封板焊接在所述第三焊接组件上,形成多腔体焊接车架;其中所述中间筋板为多条横向加强筋和多条纵向加强筋。解决原焊接方法人员在狭小的封闭空间焊接,行动不便,焊接产生的有毒有害气体无法扩散,易产生中毒、窒息等风险。同时由于焊接空间狭小,光线不足,因此焊接质量难控制的问题。
