Practice - A few questions on the tig

admin

Hey guys, Whilst I know that what I've done in this thread is very very simple for most of you, I'm quite new to TIG and I've been doing a welding course for the past two months. Have been focusing on the TIG, because I'm pretty comfortable on a MIG, and this is where i want to improve my skills. I made a gate the other day and thought it would be a good time to practice a real project on the tig, instead of joining scrap together every night. Can someone tell me why when I get to the corner, I get a bubble blowing out. Is it something to do with air escaping the tube? Is there a method I can employ to get a nice finish on that corner. It looks like I stopped and started again, which I did not. Also, just overall quality of the weld and where I can improve would be great. This is 1.6mm box tube in mild steel.Tig was set to about 45 amps, using a Thoriated 2.4mm tip with a number 5 ceramic nozzle.

Reply:I have a pedal, but didnt use it here. I have a push button on my torch.
Reply:Having the same difficulty on corners myself, the pedal would help. That or a 4T setting (or 2T upslope/downslope) to reduce amps right near the corner. And I noticed when *I* did it, it was because I was still holding the torch as if I was on the flat, instead of bringing it straight vertical/following the corner. Others with mega experience will chime in, if I am wrong correct me! I can take the criticism.
