Background
At present, new energy automobiles have far-reaching influence on the market, and the main production and manufacturing processes of the new energy automobiles are MIG welding, namely 5-series aluminum profile welding, 6-series aluminum profile welding and die-casting aluminum part welding. Because the traditional welding machine has large heat output energy, an arc shape and instability, the temperature can be gradually increased along with the increase of time, and the shrinkage is uneven and uncontrolled after cooling. Particularly in the area with longer welding lines, the heat quantity is higher and higher, and the deformation after welding is large, so that the assembly of the next working procedure is difficult. The welding requirements of the aluminum casting are higher, and the internal air holes are too many after welding, so that the strength of the automobile body is seriously threatened.
With the breakthrough and update of modern technology, the laser welding technology is increasingly applied to the fields of manufacturing industry, new energy automobiles, aerospace science and technology and the like. The laser-arc composite welding can improve the defect of pure MIG welding, greatly enhance the process adaptability, improve the weld joint formation and improve the joint quality.
When arc welding seams or curves are welded, the arc welding seams or curves need to be converted at multiple angles in a three-dimensional space to ensure that the laser beam light spots and the electric arc of the MIG welding machine are at opposite set positions, and not only the moving speed of the opposite positions, but also the moving position accuracy are controlled. Therefore, the laser compound welding control welding head is required to adapt to the adjustment of various positions and various directions so as to meet the laser compound welding requirements of workpieces with various shapes.
