What is the laser welder application? Laser welding technology and laser welding machine are widely used in manufacturing, powder metallurgy, automotive industry, electronics industry, biomedicine.The laser beam is easy to focus, align and be guided by optical instruments. It can be placed at an appropriate distance from the workpiece, and can be guided between tools or obstacles around the workpiece. Other welding methods cannot be used due to the above-mentioned space limitations. Laser welding is one of the important aspects of the application of laser material processing technology.
