People in a wide range of application of laser welding technology, while also constantly be in-depth study of its shortcomings, the use of the heating performance of the other sources of heat to improve the laser heating of the workpiece, on the basis of maintaining the advantages of laser heating, thereby laser and other heat sources with hybrid Welding Assembly, the main laser arc, laser and plasma arc, laser and induction heat source hybrid welding, as well as dual laser beam welding. Hybrid welding can increase weld penetration, improve joint performance, reduce equipment costs, and increase the welding Welding Wirespeed and productivity. In short, laser welding and high production efficiency, stable quality and reliable, good economic and social benefits. In new equipment, new materials, new technology and new technology after another, the era of constantly updated, the producers not only to understand the characteristics, advantages and requirements of laser welding, this field should be recognized as a lot of innovation and future trends, the only way to grasp technology trends, can always walk the forefront of the times.
