Up Topic Welding Industry / General Welding Discussion / 5G cap with 3/32 6010
- - By Robert Turney (*) Date 03-16-2009 01:49
My test is a 4 inch 5G 3/32 6010 all the way out down hill.  Im having a problem with my cap all of the sudden.  If I go slower my cap looks really cold, but if I move fast it looks really good.  It almost seems too fast, but I was told the faster you move the prettier the cap.  Of course you cant go very far with a 3/32, but my tie ins look fairly decent.  Any help is appriciated.

Bend them and see how it goes.  If they look good and bend good than there is nothing worng with it.  Some people run hotter, colder, faster, slower, and have different techniques.  What it boils down to is what works for you.  If you can get your tie-ins to look good than your good to go.  I worked with a guy who capped about 20 amps colder than me and our caps were very close to looking the same.  "Differnt strokes for different folks"

4 inch pipe 6010 root, hot, and cap with 3/32.  Yes you read it right.  .237 wall.

That's just making the welder work harder than he needs to.

Hopefully it's just for the test and not for production. lol

You ever heard of Centerpoint Energy?  Well thats our test to weld on distibution pipe.  Four passes.

I just tested for centerpoint transmission. 12inch on 45 and 2inch on 45. Ran bead with 1/8 and hp and cap with 5/32 on 2inch. 12inch 5/32 and 3/16

I've tried slow, fast, whipping, circles and all sorts of stuff on my cap. Seems like the fast circles lay out the toes well, tight ripples but coming down the side I may break into a whipping motion instead of circles, just depends on how the pool is flowing that day I guess. I understand what you mean about "seems to fast" but if it works, toes are tied in, no undercut then roll with it. On my slower caps it tends to build up and the ripples are not as tight as I like, but mostly I run 1/8th unless 2" then its 3/32" root, hp and maybe cap unless I just feel like running a 1/8th cap.

Obrien said it best, "different strokes for different folks". All the kids at school run there vertical up 1/8th 7018 on the easy bake oven settings(140's +), I ran mine in the 110-115 range and root burned in, all looked great/tied in and passed x-ray without flaws. I tried running one on 135 amps and looked like I had a dirt dobber on the end of the rod. Everybody has a different technique, just finding your thing. Also stated, cut them out and bend them, see what happens. I know one thing I've noticed, when I was doing practice runs I'd bevel at the specified 37.5 degrees but when I started welding gas pipe and saw the factory bevel I thought, that ain't no 37.5 degrees. I like to get it around 30 degrees. Just makes it better and don't have to cover an acre of gap on your cap because of the angle. Just how I like it though, may not be what the next guy thinks.

I tested the other day and didnt have any trouble.  Passed the bend test and my fillet weld looked good.  No more than we weld im going to have to practice, practice, practice.  As for my cap, I found my speed I liked and stuck with it.  We can cap with a 1/8 6010, but I like to stick with the 3/32 all the way out so I dont have to turn up the machine.  Thanks for the advice.
