Abstract
The invention discloses a laser welding gas shielding device. The laser welding gas shielding device comprises an installation substrate used for being fixed to a laser welding head and a clamping mechanism connected to the installation substrate and used for clamping a nozzle. The installation substrate is provided with an installation hole coaxial with the laser welding head, and the laser welding head can pass through the installation hole. The clamping mechanism is installed on the installation substrate by rotating in the axis direction of the installation substrate. Due to the fact that the clamping mechanism used for clamping the nozzle is installed on the installation substrate by rotating in the axis direction of the installation substrate, if the nozzle and a welded workpiece intervene when variable-angle welding seams and arc welding seams are welded, the clamping mechanism can be adjusted to rotate relative to the laser welding head so as to avoid the intervening portion of the welded workpiece, normal welding is not affected; and it is unnecessary to replace the nozzle, so that the welding efficiency is improved.
