What is Laser Welding and How Does It Work? | Laserax
As the energy from the laser beam is absorbed by the surface, the heat causes the surface to melt, forming a molten pool that resolidifies in a few milliseconds. Think of laser welding like a magnifying glass and the sun. If you focus enough energy on a metal surface, you can melt it—and even vaporize it in some cases.
