Laser welding, also known as laser beam welding (LBW), is a method that uses a laser to join thermoplastics or types of metals together. Metals can include aluminum, carbon steels, stainless steel, or titanium. Laser welding works in two essential modes: conduction limited welding and keyhole welding. The mode of the laser beam interacting with the material it is welding is contingent on the density of the power of the beam as it contacts the workpiece. A targeted heat-affected zone with high welding rates is vital.

Nitrogen gas is used around the laser tip for two purposes: maintaining the proper weld temperature and getting oxygen and moisture out of the beam path.

Recommended Nitrogen Systems for Laser Welding 

To achieve a first-rate weld, it is imperative to maintain an accurate weld temperature and to remove any moisture and oxygen in the path of the laser beam. Nitrogen gas delivers both of these objectives with accuracy and dependability. All types of use profiles can be accommodated by a nitrogen generator. We will use our 35+ years of experience to provide the best specification to meet your needs.

Facilities with laser welding are an excellent fit for the championed nitrogen generation systems made by On Site Gas. To learn more about how our nitrogen generators are used for laser welding, contact a member of our team today!
