Choosing a gouging method - The Fabricator

Gouging with air on carbon steel can leave a thin, dissolved, nitrogen-rich layer on the gouged surface. In certain welding situations, this can cause microporosity. Normally, this is a problem only in very high-quality welding situations and can be removed with light grinding on the surface or by using inert gas as the plasma gouging gas.
