The invention discloses a rubber film sealing coal gas cabinet bottom (top) plate welding method, which comprises the following steps of selecting welding specification parameters and welding technical requirements, welding middle plates in sequence and the like. The method has the advantages that the welding deformation and the instability deformation of a rubber film sealing coal gas cabinet bottom (top) plate can be effectively controlled, and the complicated process of re-repair after the welding completion in the prior art is omitted, so that on the basis of ensuring the welding quality, the integral construction quality of the rubber film sealing coal gas cabinet is greatly improved, meanwhile, the construction period is shortened, and the construction cost is reduced.
