Laser welding is a precision welding method that uses a dense laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. Laser radiation heats the surface of the workpiece, and the surface heat is diffused 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. Because of its unique advantages, it has been successfully applied to precision welding of micro and small parts.

Laser welding technology belongs to fusion welding, which uses laser beam as energy source to make it impinge on the weldment joint to achieve the purpose of welding.

QCW laser welding machines are ideal for spot welding, seam welding and long pulse drilling applications. Compact structure design. Because of its electro-optical conversion efficiency> 30% and maintenance-free operation, its cost-effectiveness is far superior to conventional YAG lasers.
