What Is Laser Welding?

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. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.
China's laser welding is at the world's advanced level. It has the technology and ability to use lasers to form complex titanium alloy components of more than 12 square meters, and has been invested in the prototype and product manufacturing of multiple domestic aviation scientific research projects. In October 2013, Chinese welding experts won the highest academic award in the field of welding-the Brooke Award, and China's laser welding level has been recognized by the world.
