Beschreibung
Zusammenfassung:	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 diffi
