How do I eliminate the porosity (or what causes it) in a pipe welded with1/8 7018 on 4"+ pipe? I've had this problem before, and I would like to eliminate it. I beleive that I may be holding the rod out too far at times (the porosity is sporadic). If that's the case, can I hold the tip right into the puddle, or just about into the puddle? Thanks to all.
