Vertical Welding Question
So in class we did a little vertical fillet welding, bottom to top,
arc welding, 6013 rods, IIRC. Anyhoo, I got pretty good at it, except that I have hell establishing a puddle at the bottom without it falling out a time or two. I asked the teacher (well, a sub) and all he did was tell me to preheat my rod by holding the arc a little long for a bit after striking it. I'm pretty sure I was doing that anyway, since I made a habit of it, but I went and tried anyhow, no change. How to get a puddle established when welding up? Another question, possibly related: Sitting and thinking, I believe my technique might have been wrong, after I got a puddle going, even if I did get a good weld out of it. I had my rod pointed upwards into the weld just a little, maybe 10 degrees or so. Is that correct, or was I supposed to lean it the other way? Pointing it down into the weld would be more consistent with the way I hold it when welding flat. And would that be the source of my starting problem? Spring break now, so can't play anymore for a couple of weeks. Damn vacation! -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

news I had my rod pointed upwards into the weld just a little, maybe 10 degrees or so. Is that correct, or was I supposed to lean it the other way? Pointing it down into the weld would be more consistent with the way I hold it when welding flat. And would that be the source of my starting problem? My gut feeling is you'd want it pointed slightly into the deposited bead, but then again I go out of my way to make my joints flat so I'm no exspurt on this. g Spring break now, so can't play anymore for a couple of weeks. Damn vacation! Bah! Get your own Which reminds me, we got a 50A circuit put in, now I can weld in style at maximum amperage... woohoo! Now I just need to install the rectifier, and HF starter, and argon bottle, and tungsten rod, and I'm set! ;-D Tim -- "California is the breakfast state: fruits, nuts and flakes."
