Reciprocating laser arc composite surfacing equipment

The utility model provides reciprocating laser arc composite surfacing equipment, belongs to the technical field of welding processing, and solves the problem of height difference caused by one-way material increase. The device comprises an aluminum alloy frame, a rotating system, a parameter adjusting system, a three-dimensional motion system and a laser arc composite welding gun system. The rotating system is installed on the upper portion of the aluminum alloy frame. The parameter adjusting system is installed on the lower side of the L-shaped composite welding gun fixing plate. The three-dimensional motion system is mounted in the aluminum alloy frame according to space motion during surfacing; the laser electric arc composite welding gun system is installed on the front side of the parameter adjusting device through bolts. The relative position of the composite welding gun system can be automatically adjusted at the welding end point of the upper layer, so that the composite welding gun is always in a la
