How to weld 6G Copper Nickel Pipe Test Guide for Navy Shipyards

This is a guide to help someone prepare for the copper nickel 6g pipe test 90/10 with 1/16 RN67 filler wire.

Interesting video, never saw or dealt with that type of material before myself.
I like how you show mistakes when they occur and ways to correct them when they happen.

Oh I was just waiting around for the Bend part

[marvinharms]

Good stuff man. That's the way it's done here on my side of the world. S Africa that is. Cunifer will keep you on your toes. Before you know it- its role up time!

[amossnowdaharleyman]

I was a Machinist Mate 1st Class in the Navy and on my last ship I stick welded on 600PSI steam lines for repair and valve change outs. The Hull Techs (welders) kept saying they weren't "qualified" and once I showed the Chief Engineer (full Commander) that I could do it he relegated all of that to me. Never did figure out why the HT's refused to do it. My welds never failed btw and passed closer inspection when we had yard repairs and refits.

Great video, are you running downhill in the 6G and 5G position?

[Allanth]

Currently doing this in the 6g position and a minimum 60 degree bevel. Not able to walk the cup, can weave. Just having an issue with weld drooping from top to bottom toe. Miller dynasty 400 settings for root, fill, cover?

[patrickfarley]

Where would this be used? I'm very use to seeing pipe being back filled so the root has a more cap like appearance on the inner diameter as opposed to a sort of groove look such as this joint has.
Thanks very much sharing your knowlegde!
God bless!

Im having difficulty in the overhead. Everything from suck back to undercut.

[bigjim]

Welds like stainless crossed with iconel

[koshjosak]

I weld a ton of this stuff. Have you ever tried the RN60 Copper Nickel wire? Far superior to the RN67 in my opinion. Runs much cleaner and less dead.

[kenneyminter]

Does it run a lot like inconel? Looks like it at least.

[chrisrios]

Man I never seen something so dirty, that is difficult

[johnbrennan]

Here in the UK we weld CU/Ni alloys with mix gas of either 2.5% Hydrogen 97.5% Argon or for heavy wall 70/30 CU/NI or for Monel alloys try 5% Hydrogen 95% Argon the hotter arc and cleaning from the hydrogen reaĺly make a big difference

[mirfan]

How much power root pas and caping pas

[echoserenade]

Whats the best way to cut the arc on the cap to prevent pin?

[AintS]

That's a great video and that puddle... Very misleading to work with when you don't know to feel for that drop. Thanks for posting!

I was aboard CG-48 in Bender Shipyard several years ago.
