The invention discloses a novel laser welding machine for automobile part machining. The novel laser welding machine structurally comprises a welding machine body, an ascending-descending movement machine, a front-back movement machine, a left-right movement machine, a positioning plate, a welding machine head, a machine head movement rack, a machine head ascending-descending rack, a data consoleand a welding machining mechanism, wherein the ascending-descending movement machine is mounted on the upper portion of the position, located on one side of the data console, of the welding machine body; the ascending-descending movement machine, the front-back movement machine, the left-right movement machine and the positioning plate are arranged from bottom to top; the front-back movement machine is movably connected with the left-right movement machine; and the data console is disposed on the side, close to the ascending-descending movement machine, of the welding machine body. Movements are achieved during equipment running by performing data setting on the shapes of parts, manual auxiliary fixing operation is not needed during the procedures of spot welding, butt welding, stitch welding, seal welding and the like, the labor cost is reduced, welding is fast and accurate, the welding smoothness and attractiveness are further improved, the safety is guaranteed, welding for the different parts is achieved, and welding is convenient.
