Embodiment Construction
[0034] Such as figure 1 As shown, the laser welding system used in the embodiment of the present invention includes a laser generator 19, a transmission fiber 18, a welding manipulator 8, a laser welding head 6 that is connected to the laser generator 19 through the transmission fiber 18 and installed on the welding manipulator 8, a high-pressure gas Column nozzle 5 , protective gas nozzle 3 , temperature sensor 10 .
[0035] Both the high-pressure gas column nozzle and the shielding gas nozzle are connected with the laser welding head through the fixed bracket 4, so that the laser welding head, the high-pressure gas column nozzle and the shielding gas nozzle can move synchronously relative to the base metal, and the laser welding head, the high-pressure gas column nozzle and the The shielding gas nozzles are set to be aligned with the welding position.
[0036] The temperature sensor 10 is placed below the starting point of welding for real-time acquisition of the backside t...
