Welding

Nitrogen, 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 Learned

A great deal of care needs to be exercised to ensure complete inert gas (argon or helium) coverage during welding.
