Hello!
I'm having trouble locating help learning Oxy-Acetylene welding for 4130 here in Atlanta, Georgia. The local trade schools have virtually no Oxy-fuel welding and the TIG classes they do provide cost thousands of dollars. I've asked local A&PS and their response is they all farm out the work and don't know anybody locally. I guess the world has all gone to rivets and Oxy-fuel is a lost art!
My problem right now is when I try to practice welding 5/8ths x 0.032" 4130 at right angles. I do the weld like the books, videos and the plans all say to do it, in quarters. It looks like i'm burning the weld. When I am finished its lumpy and looks like a cold lap even though I am certain there was a puddle there!
Its so frustrating to come from not knowing anything to pushing puddles around a plate to doing t-joints but now tubing is giving me a headache! The 4130 is so darn thin and it just burns away the moment the smallest of flames gets around it that i'm just about to kick myself in the butt.
I am at a point where I need some professional supervision to move me over this hurdle. Where do I find this help?
Thanks,
JB
PS. Airventure isn't and option. No, no EAA Oxy-fuel classes in Georgia, only TIG. Sorry, I'm not spending the money on TIG, there is no benefit or advantage (and don't start on me, go to
http://tinmantech.com and yell at him, I'm not listening anymore, this is a religious war I want no part of). I already have all the books and videos from EAA, Aircraft Spruce, Tony Bengelis, Tinman and everybody else. I need a human being who can watch me, tell me what I'm doing wrong and help me!
