Welding is required when processing parts in petrochemical equipment.

[0003] A welding device for metal parts processing with the announcement number CN213969653U authorized by China is used. A first group of parts to be welded are fixed by a left arc plate and a right arc plate. A worker puts a second group of parts to be welded on the outside of an expansion rubber cylinder, controls the telescopic rod to move upward by a third cylinder, and drives the baffle to move upward. During the upward movement of the baffle, the expansion rubber cylinder is continuously squeezed, and the second group of parts to be welded are tightened and fixed by the expansion rubber cylinder.
