The QCW laser welding machine is an ideal choice for spot welding, seam welding, and long pulse drilling applications. Compact structural design. Due to its electro-optical conversion efficiency>30% and maintenance free operation, the cost-effectiveness is far superior to conventional YAG lasers. Mainly aimed at welding thin-walled materials and precision parts, it can achieve spot welding, butt welding, overlap welding, and seal welding;
