You won't find it in any approved WPS, but I've seen it done. Also seen it done with stick welding, dipping a second rod in the puddle for filling large gaps. The slang term for it was "Mexican TIG", which sounds like an insult, but actually referred to people having to make do with what they had to get the job done. Adding the extra metal, along with the extra cooling from a cold rod being introduced, works pretty well with practice. In the "stick on stick" method, I've seen people beat the flux off the second rod to avoid an excess of slag.Trapperdude464 wrote:Hey i know its been awhile sense ive been on here sorry ive had alot goin on.

It was thin walled pipe 4 inch in diameter and i believe they said it would have about 80lbs of pressure on it. If that sounds right

I have done that with SMAW. Every time my boss would see me doing that, usually to fill in a big gap on something, he would say something like: "There goes Ghetto Gary welding again!" So ....
Hey, if it works it works! I guess it depends on the necessary structural integrity of what you are doing. I knocked all of the flux off of any 'filler' rod before I used it, leaving what we called a coat hanger.
And yes, before school is done I do show this to the students and explain when it can and can not be used. It is just another skill to throw into your arsenal of junk welding skills.

We call it "Texas TIG" hereabouts. Had to do it about a month ago on some bad fit-up on a fence made with used oil field pipe. Just knock the flux off an electrode and go for it.
