Laser Welding

laser weldingLaser welding is a very precise process used to perform delicate welds on a wide array of materials. The key aspect of laser welding is the use of high energy light to melt the material, unlike TIG or other electrical welding processes which use electricity. Additionally, there are no grounding concerns with laser welding. In fact, the material does not even have to conduct electricity. This opens up the door to the welding of nonconductive materials.

Laser welding works like this. The focal spot of the weld joint is aimed with an enormous amount of light energy which is converted to thermal energy forming the weld spot. This weld spot time is mere milliseconds. What this means to the customer is greatly reduced or eliminated heat affected zones or "sinks". Laser welding can be used on intricate parts which could never have been processed with conventional methods due to the residual heat introduced to the part. Laser welds also have better grain structure which helps with color matching.

Materials as thin as .002" can be joined with laser welding. Distortion and heat input are very minimal due to the pulsed nature of the laser welding process. Conversely, very large molds or die sections that need precise welds applied in difficult-to-reach areas can also benefit from laser welding. Many times, intricate assemblies can be laser welded without disassembly which helps to decrease downtime and cost.

Our laser welding services are perfect for:

  • Fixing or eliminating engraving
  • Sharpening of dulled or rounded corners
  • Fixing flash problems
  • Welding diamond-polished areas
  • Welding textured surfaces
