Laser microwelding


Laser microwelding explained in a few words:

Laser microwelding is a fusion welding process performed  with or without the addition of filler metal. The light energy is concentrated on a small area (a diameter of 0.02mm to 2mm) during a short period of time (approximately 2 to 50 ms). This reduces the heat affected zone (HAZ) , which minimizes distortion while allowing to weld in close proximity to sensitive materials  such as polymers or composites. Our control of the welding parameters (i.e. pulse duration, , frequency and intensity) allows us to optimize the welding parameters for specific alloys.

Alloys frequently welded by this process are:

  • Stainless Steels
  • Nickel Alloys
  • Titanium
  • Platinum Alloys
  • Gold

We keep an inventory of filler metals from different alloys with diameters ranging from 0.003” to 0.020”. The use of a microscope and digital controls ensure an excellent repeatability of results as well as an exceptional welding quality.
