Laser welding comes in a variety of forms, as does traditional welding.  Laser welding can be used to melt and bond two surfaces of the same material.  In other cases, dissimilar materials can be welded. In the case of brazing, a wire with a lower melt point is melted under the laser and permanently adhered to the surface below.

Laser welding can also occur on the top layer or in other locations.  For example, when welding plastics, the 1064 nanometer laser will pass directly through a clear plastic, then the laser energy will be absorbed by a dark colored plastic, so that the laser weld is internal. This is a typical application utilized by the automotive industry.

There are a variety of technologies for laser welding.  First, select your laser type, then choose amongst the machines for your best fit.
