hello,
i've been playing around with TIG welding recently, both steel and aluminium, and i have a few questions. i've gotten to the point where i can lay a good straight bead with filler rod on flat plate but now i want to weld around pipe. i've also read a lot about "walking the cup" but i don't quite understand the process (if it is the correct techinque for welding pipe). As you're welding and rolling the cup in a zigzag motion are you welding away from the filler rod? when welding on a flat plate i always am pushing the puddle towards the filler rod. also, is it bad to stop a bead in order to turn your tubing or pipe and then restart the bead? i did try some practice pieces of welding tubing to flat plate but i couldn't get more then
1/4" before contaminating the tungsten. i just don't know how to weld out of position i guess. any advise would be appreciated or links to webpages.thanks matthew
