Laser cleaner online store UK 2024: Need low heat input? Choose laser welding. Close up of a laser welding fixture. Laser welding transmits heat in small, controlled areas. Other processes, like MIG welding, have greater heat inputs, which causes more residual stress on the component. Controlling the heat affected zone with laser welding keeps more of the metallurgical structure intact. The result is a higher quality weld that require less finishing and heat treating. Laser welding’s-controlled heat affected zone also makes it possible for us to weld the exterior of a device without harming thermal-sensitive internal components. Read additional details …
