Laser welding

Latest updated: Sep 24, 2024

The process of achieving a sealed or fixed connection by emitting high-energy continuous laser beams to melt the welding area, while controlling parameters such as the power, focus, and speed of the laser welding gun.

Note: The welding appearance should be smooth, with no visible defects such as cracks, pinholes, or craters.
