WeldingNitrogen, hydrogen, carbon dioxide, and mixtures containing these gases shall not be used
Welding with alloy-matching fillers is recommended, preferably using extra Low Interstitial (ELI) filler wires
SPECIAL RECOMMENDATIONS
Lessons LearnedA great deal of care needs to be exercised to ensure complete inert gas (argon or helium) coverage during welding.
