Description

Technical Field

[0002] Laser welding is an efficient precision welding method that uses a high-energy-density laser beam as a heat source. 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.
