Filter plate, filter plate welding clamp and welding process

The invention relates to the field of welding, and particularly discloses a filter plate, a filter plate welding clamp and a welding process. The filter plate comprises a fixed plate and a filter disc. The filter plate welding clamp comprises a supporting seat, the supporting seat comprises an inner supporting plate used for containing an inner ring, an outer supporting ring used for containing an outer ring and a supporting strip used for containing a connecting strip, and the supporting strip is connected between the inner supporting ring and the outer supporting ring; an adsorption mechanism is arranged on the lower side of the supporting base and comprises adsorption covers arranged on the two sides of the supporting strip, an air suction pipe connected with the adsorption covers and a pump connected with the air suction pipe, and adsorption openings are formed in the upper ends of the adsorption covers. The filter plate adopts a double-layer structure, so that the updating cost is reduced. And the mesh i
