Looking for some tips on pipe with 1/8 7018. I have good control with 3/32 but my 1/8 is slacking. Basically I have to stay around 105-115 amps to get a decent looking bead (is this normal?). If I go any higher the puddle starts blowing out on me. I've varied travel speed and rod angle and still haven't come up with anything to solve the problem. I mainly just surfacing the pipe with stringers right now. The material is carbon steel pipe, 6" sch 40/80/160 (whatever is in the scrap bin) and as previously stated 105-115 amps. Any advice is greatly appreciated.

Reply:That's about where I run 1/8 inch 7018 on pipe. I either control the flow of the puddle with arc length, or with the arc force. Proper arc length is essential when going around a pipe.

Reply:For 6'' and even 8'' some guys will only use 3/32 lo hi. Better control and less material to play with as you stated. It depends what you are comfortable with. i hate 1/8'' but sometimes it is the best choice. It just takes more practice.
Reply:as long as it ain't sticking on you, you're good. You can't run a whole lot of heat with 1/8 doing stringers. Try weaving it some, that'll keep it from dripping out on you. Here's one I did with 1/8th on a heavy wall steam header in a power plant, this stuff was pretty thick |
