Web31 mrt. 2024 · Laser Beam Welding (LBW) is a welding process, in which heat is generated by a high energy laser beam targeted on the workpiece. The laser beam heats and melts the edges of the workpiece, forming a … Web4 aug. 2024 · Lasers release energy by emitting laser beams of specific wavelengths. When the beam hits the surface, the material reflects most of its energy. The remaining energy is absorbed and converted into heat. For laser etching, the material must absorb just enough energy to melt.
