Seven Tips for Inert Gas Welding


Effective welding purging is only achieved by making sure that oxygen is displaced from the purge zone prior to and during welding.


Any residual oxygen can cause significant loss of corrosion  resistance and a reduction in joint strength. It is therefore essential to seal the pipe either side of the joint and maintain this seal throughout the process.


The residual level of oxygen in the purge zone needs to be consistent with the welding procedure so continuously monitoring to ensure compliance is crucial.
