hand held metal laser https://www.laserchina.com/handheld-laser-welder/ A hand held metal laser (more correctly called a handheld metal laser welding machine) is a portable welding tool that uses a high-energy fiber laser beam to join metal parts. Unlike traditional MIG or TIG welding, it does not use an electric arc. Instead, a focused laser melts the metal at the joint, creating a strong, clean, and precise weld with minimal heat distortion. It is widely used in steel fabrication, automotive repair, and industrial manufacturing because it is fast, easy to operate, and works on materials like stainless steel, carbon steel, and aluminum.
