Welding equipment

The utility model provides welding equipment which comprises an equipment body, a rotating assembly and a welding assembly, the rotating assembly and the welding assembly are connected to the equipment body, the rotating assembly comprises a rolling body capable of rotating relative to the equipment body, and the rolling body is used for rolling along the first surface of a first to-be-welded part and enabling the second surface of the first to-be-welded part to be connected to a second to-be-welded part in a pressing mode. The first surface and the second surface are arranged oppositely. The welding assembly is used for conducting penetration welding between the second surface and the corresponding surface of the second to-be-welded piece. The first to-be-welded part and the second to-be-welded part are tightly attached through the rolling body, a molten pool stable in form is formed, the welding quality of penetration welding can be improved, follow-up shaping and polishing treatment can be omitted, and the welding process is simplified.
