Handheld Laser Welding Gas

HANDHELD LASER WELDING GAS

Laser welding machine also require for gas assistant welding, similar to TIG welding (argon welding), Need to use argon gas as the shielding gas to protect the weld area from oxidation.

Normally we use argon gas for stainless steel and aluminium welding, gas pressure recommend to use 10-20 bar.

Nitrogen-N2-Gas-Cylinder

Nitrogen is another option gas for welding aluminium welding and stainless steel welding.

You can use compressed air for assistant welding, because more than 70% air is nitrogen. Welding quality is poor than welding with Nitrogen and Argon gas One thing need to pay attention is the air should be FREE OIL, AND FREE WATER. otherwise will damage the optic lens of the laser welding gun.

And we will use Co2 gas for carbon steel welding assistant.

Many more advantages to use Nitrogen generator instead of the N2 cylinder.

1. Higher purity, good welding effect, no need polishing.
2. Cost saving, short payback period, and maintenance-free.
3. Stable and constant output nitrogen support you to weld continuously.
4. Save time and labor costs wasted by exchanging the gas cylinder.
5. Safety and No need to transport or special storage.
