Nitrogen for use in arc welding

Gas-shielded welding is a form of arc welding and is carried out in an artificial atmosphere composed of a shielding gas (nitrogen). In this context, the aim is to protect the arc and the molten pool from the oxygen that is found in the natural atmosphere. Unwanted chemical reactions with oxygen include corrosion and combustion. The aim is to avoid reactions of this type. High-quality gas protection composed of nitrogen is important, particularly for maintaining the product quality of steel, aluminium, magnesium or titanium. An inadequate protective atmosphere can lead to colour changes, pores or rust on the materials.

In addition to its use as a shielding gas, nitrogen also serves as an auxiliary gas with which the quality of the weld seam and arc stability can be improved.

With our nitrogen generators, we supply high quality solutions for the stationary and mobile production of nitrogen for different applications, including for low volume requirements.
