Metal welding

General Industry

Nitrogen is use in many metal heat treatment activities like annealing, hardening, sintering. And also for welding, brazing and soldering.

Purging

The nitrogen is used to purge the surface of the metalic part that is heat treated. It prevents oxidation of the metal.

Carbonizing

Carbonizing is another application were nitrogen is frequently used because of the need for an oxygen free atmosphere during the carbonization process.

Plastic Injection Molding

In plastic injection molding nitrogen is often used as the assist gas that prevents oxidation of the plastic, that leaves the mold with a clean surface finish. Nitrogen is also injected with the plastic creating air channels which results in less plastic needed without cutting the strength.
