Welding equipment for automobile parts

The invention belongs to the technical field of alloy welding, and particularly relates to automobile part welding equipment which comprises a leveling table, a control unit is arranged at one end of the leveling table, a front side plate is arranged at the other end of the leveling table, a correcting unit is arranged on the top face of the front side plate, and a main repairing unit is arranged at one end of the correcting unit. An auxiliary repairing unit is arranged at the other end of the main repairing unit; through relative movement between the first chamfering piece and the to-be-welded piece and between the second chamfering piece and the to-be-welded piece which are perpendicular to each other, complete repairing and polishing of a weld joint area of the to-be-welded piece are achieved, the local stress concentration and embrittlement phenomena are eliminated, and meanwhile the structural strength of the to-be-welded piece is improved; and through meshing between the transmission rack and the driven
