Reply:you not gonna get a ton of material on the back. when ever you do open root like that with wire feed. i just to my metal core test 2G 3/32 gap 1/16 land. i got if flush with a keyhole across. but youll stilll have to back grind it 3/16 - 1/4 " back and 1/4" wide u groove and fill to pass an inspection. unless you have a bar then its a different story.6G zirconium 702 GTAW 2" xxheavy6G P.E.D. carbon steel GTAW 2" xxheavy3G titanium Gr. 2 - Gr. 7 GTAW up to 3/4" 3G 316L stainless GTAW up to 1" 3G carbon steel GTAW up to 1" 3G Hastalloy GTAW up to 3/4"1G tantalum GTAW up to .060"
