The invention discloses a gas protection device for laser-arc hybrid welding and a laser-arc hybrid welding machine with the gas protection device. The gas protection device for the laser-arc hybrid welding comprises a protective gas chamber which is provided with a connecting end used for connecting a laser head and an opening end that is opposite to the connecting end; an air injection device which is arranged in the protective gas chamber and is used for injecting protective gas towards the opening end in at least two directions; and an installation part for an arc welding device which is arranged on a side wall of the protective gas chamber and is used for installing the arc welding device. The laser-arc hybrid welding machine comprises the laser head, the arc welding device and the gas protection device for the laser-arc hybrid welding, the connecting end of the protective gas chamber of the gas protection device is connected under the laser head, and the arc welding device is arranged in the installation part for the arc welding device. The gas protection device for the laser-arc hybrid welding and the laser-arc hybrid welding machine have simple structure and can effectively avoid shielding laser as a plasma drifts.
Description
technical field [0001] The invention relates to a laser hybrid welding equipment, in particular to a laser arc hybrid welding gas protection device and a laser arc hybrid welding machine with the gas protection device. Background technique [0002] As a precise, efficient and fast high-energy beam welding method, laser welding has been more and more widely used in the aerospace field. However, conventional laser welding also has some problems and defects, such as low utilization rate of laser energy, high assembly precision requirements, and expensive equipment. In order to solve these problems, several new laser welding technologies have been proposed in the prior art: one is multi-focus laser welding technology, this welding method can improve the utilization rate of laser energy, improve the stability of the welding process, and improve the quality of the weld seam , while reducing the requirements for assembly accuracy. The other is the hybrid welding technology, which...
