Is there a significant difference in the quality of a weld if the rod is pushed instead of dragged? I'm welding 5/8" dia nuts to 1/2" steel with 3/32 6010, and the bead looks "prettier" if I push the rod...........James

Ok, the dummy has to chime in
Dragging means letting the puddle follow the rod as I bring it towards me.????????
6011, 6013, 7018.. I pull the rod towards me to dig a trench, then go back into the puddle to fill the trench. I don't call it whipping, it's more of a very slow progression where the arc is always in the puddle, or maybe within a hair of it. Just enough to make progression. Only time it's out of the hot puddle is to dig a trench about 1/8 inch ahead of the puddle as it's progressing towards me. Very fast movement where the puddle still is fluid.
I'm all screwed up on the terminology I guess

Well that's what confuses me.
I certainly wouldn' t call these whipped welds. Maybe I'm wrong
A true drags seems to me to be what you could do with a wire semi automatic welder. Point, shoot, and progress. The machine builds the weld instead of your hand.
There has to be some hand motion back into the puddle to build the weld. A true no movement drag would leave a low weld. No filler

Now you got me thinking about everything I do. That's good!!!!!!
Getting purely theoretical:dizzy: How is it possible to build filler without allowing the puddle to "freeze" to some degree? Even if just for a millisecond. Any motion imparted to the rod takes heat out of the zone. A side to side motion directs heat into different parts of the puddle. It removes heat in order to allow the metal to slightly solidify.
Otherwise we could just point the rod into the corner and make a prefectly satisfactory fillet. You have to work the toes of the fillet.
Washing the puddle against a piece of flat is the same thing. The heat is manipulated. The puddle is allowed to cool to some degree, otherwise the undercut would be phenominal. We'd literally eat the edge of the plate away.
Ok, I'm getting weird...........er:laugh:
