Laser welding uses an amplified beam of light to produce a solid weld with an almost invisible seam in seconds. It sounds complicated but is really quite simple. Laser welding uses a specific wavelength of light to accomplish the welding process.
The beam of light emitted from a laser welder is concentrated, adjusted and controlled by the operator, in much the same way as the flame of a soldering torch is regulated by a jeweller. However, compared to soldering, laser welding is faster, cleaner and more cost-effective for many manufacturing and repair applications.
