Laser-electric arc hybrid welding platform for thick-wall pipeline

The utility model relates to the technical field of metal pipeline welding, in particular to a thick-wall pipeline laser-electric arc hybrid welding platform. The device comprises a Y-axis guide rail system, an X-axis guide rail system, a Z-axis guide rail system and a rack, the Y-axis guide rail system comprises an auxiliary Y-axis guide rail and a main Y-axis guide rail which are installed at the two ends of the upper portion of the rack, one end of the auxiliary Y-axis guide rail and one end of the main Y-axis guide rail are connected with a synchronous belt mechanism, and one side of the synchronous belt mechanism is connected with a synchronous belt motor. According to the thick-wall pipeline laser-electric arc hybrid welding platform, the electric arc welding gun and the laser welding gun are driven to complete reciprocating motion in the X direction, the Y direction and the Z direction in the space through the arranged three-coordinate sliding table module, so that the electric arc welding gun and the
