| Laser pulse spot welding machines are precision welding devices that use high-energy laser pulses as a heat source to locally and instantaneously heat and melt materials, forming individual weld spots after cooling . It is an important application of laser welding technology, particularly suitable for fields with strict requirements on welding precision and heat-affected zones. Compared with traditional resistance spot welding, laser spot welding machines have higher energy density and more precise control capabilities. |
