Anyone that deals with or dealt with welding copper nickel please help!

I welded Copper Nickel for fifteen years for Naval ships, Long Beach Naval Shipyard, Long Beach, Ca. and South West Marine, San Diego. Engloid and Pipewelder gave you good tips on how to weld this material 70-30 or 90-10 copper Nickel. I might add a few other tips. We use to use scotchbrite to remove some of the oxide prior to welding or silver brazing this material. I walked the cup and free hand both with no problems. One thing I use to hold a real close arc length . On 3/32 material I was using more heat than you maybe 110-115 amps and realy haul out. I found that using more heat and moving faster kept the haz zone narrower. We welder this with Rn67 welding rod and used RN60 to weld copper Nickel to carbon steel. If you think this welds hard, wait tell you weld it to carbon steel that is worse. If you want to have fun try and stick weld this using 9N10 stick rod boy is that fun!! The more you weld it the better you will like it.

Some FINE slag on the 9N10, 4N1A etc. A poor bead contour and you might as well put the chipping hammer down and get the burr bit out.

We only used it for BMR's on seawater vaves and sometime pump shafts. Tigged all the pipe joints socket or butt.

Would someone ban this clown.....every post I have read from jim is a jealous bashing rant. Dave

You know, for someone that starts their handle with USMC, it's apparent you have not served or have no respect for those that come after you. You say you are working for the Navy, did you ever consider that the things you are welding are for the defense of this country, and if you aren't competent and/or confident in your skills you shouldn't be welding on things that someone may depend on for their safety. We lose too many men and women to the enemy as it is, they don't need someone who thinks he's up to the job compromising their lives.
You are a disgrace.
