Got a question regarding making a dime wide puddle cap that is a nickle high using an 1/8" 70+ electrode. Can this be done and made to look good? Seems to be rather wide for such a small diameter rod... but this is what I was told. I can see doing this with a 5/32 or a 3/16. someone please enlighten me. This has been driving me crazy for about a week now trying to get it to look and run good on 12" pipe.
so your runnin a 1/8 70 plus on 12in? what wall thickness? heat and all. i weld 1/8 only on 2 in or smaller. it would be kinda hard to make a puddle cap on .375 wall of 12 in.
dime wide and dime high, maybe if you are turned down to 1480 rpm on a SA200 and in the 130/50 range. Will run into issue with gas pockets. But if this is a pipeline weld, why do you want to put on so much metal. Over flush and you are good
Its not that I want to run 8's. The company that I am trying to get hooked up with wants me to run it all the way out with them on a 12"/.375 bell hole and 12"/.250 branch. Puddle cap on the 6G and 2 pass cap on the branch. The boss is concerned of trapping too much slag with a larger rod. But I am thinking that some of their weldors do cap out with a 5. Dime wide is what he said he would like to see and a nickle or less above flush. He called it a 15 cent weld. I would prefer to cap with a 5 personally.
