A galvanometer laser stitch welding equipment

Abstract

The invention discloses a vibrating mirror laser stitching welding equipment, which relates to the technical field of laser stitching welding. The galvanometer laser stitching welding equipment includes a bottom plate, a sliding mounting seat is fixed at the center of the top of the bottom plate, the top of the sliding mounting seat is fixed to the bottom ends of three fixed sliders, and the other end of the fixed sliders slides with the side of the rotating welding ring connected, and the three fixed slide bars are respectively located at the center of the front and rear parts and the center of the bottom of the side of the rotary welding ring. The galvanometer laser stitch welding equipment can make the laser head weld around the tubular workpiece by setting the rotating welding ring, without rotating the workpiece during the welding process, and can avoid the dislocation and disconnection of the welded points on the surface of the workpiece during the rotation process. At the same time, setting the friction plate can use the rotation of the rotating welding ring to describe the welding place of the tubular workpiece, so that scratches appear on the surface of the workpiece, making the surface of the workpiece rougher, so as to reduce the reflection effect of the workpiece surface on the laser.

Description

technical field [0001] The invention relates to the technical field of laser stitch welding, in particular to a galvanometer laser stitch welding equipment. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. The welding process is of heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, etc. parameters to melt the workpiece to form a specific molten pool. [0003] Existing laser stitch welding refers to laser welding after one workpiece is superimposed on the surface of another workpiece.

Problems solved by technology

[0003] Existing laser stitch welding refers to laser welding after one workpiece is superimposed on the surface of another workpiece. For example, the stitch welding of pipes is to socket a pipe with a smaller diameter inside a pipe with a larger diameter and then weld it. Some existing tubular The surface of the workpiece is relatively smooth and has a high reflectivity to light. At this time, when the laser is irradiated on the surface for welding, part of the laser will be reflected, which will affect the efficiency of laser stitch welding.
