I always had problems with this when welding on pipe. Trying to get a filler in without blowing thru the hot pass and root, or welding smaller diameter pipe in position. Turn it up hot enough to get past the globs and you open up a whole new can of worms. 

Still have a crew up there, but cut the top of my left thumb off yesterday, it got slammed into the forklift door as I was backing up the hill and the lacht that holds it open let go. Will most like be on the stand around supervisor crew for a few weeks. It didn't come right off so I managed to stuff it back on before the shock wore off and line up the bone, the doc said I should think about taking up surgery because not often do they get but back so well aligned all they had to do was but in the stiches, the xray showed the pieces in perfect alignment So I am hopeing that it will mend up well. Another lucky part was a friend of mine ran out of work so I managed to get another pair of boots on the ground this morning so the truck is still bringing in some money so with two rigs running things won't be so bad just a little less of it. Thank god I paid that compo bill. Told the Doc that welding and surgery have a lot in common the biggest difference being is I have to fix my mistakes he has to bury his, for some reason he didn't see the humor in that as well as the rest of the people in the room must of hit a nerve.
Regards, Richard.
