Well I ain't no Brown Dog but at least I can say these are mine. Vertical Stick This was my welding "test", I was told to fill it all up and we would cut it in half and see what's goin' on
Well ... did you pass?? couple of mine: Seat pan - Cheap homemade steering wheel install tool - oil tank ... enough ...
Good stuff Paco. And yes I passed, I just wish I didn't warp the metal so much, but filling that whole piece of angle up within the short amount of required time, it was bound to happen
Need some help with my TIG technique here. Please. Trying to butt weld small (1 1/2" and 1 1/4") .065 6061 tubing. Pretty sure the problems I'm having are either torch positioning (angle or distance or both) or movement (too fast or too slow). The only way I can get a consistent bead is to go around the tube like "spot weld, spot weld, spot weld" until it's all the way around. And I know that's not right even though it passes a pressure test (most of the time anyway). I do okay on flat butt joints, inside / outside corners, and vertical. But I'm really struggling on round tubing. The shit is killing me. Been watching weldingtipsandtricks.com on youtoob but thus far Jody hasn't done a vid specifically for tubing that I'm aware of.
The easy way to weld tube but joints is with a welding positioner (sp)...think grounded turntable. Based on the pic, it looks like the distance and tip angle are what is keeping the weld from looking uniform. Its really down to just more and more practice....aluminum is really tough with starting and stopping because its difficult to control the heat reliably with the thin section thicknesses as well. you'll get it though....what your doing now is not terrible...its just not as pretty as you'd like! best, John K.
I'll 2nd the motion on what John said. It also helps ... in my huble aluminum welding opinion, that a little preheat of the pieces don't hurt (although it's thin wall to begin with). But that just me - I like to join a lot of different thickness materials. PACO
Forget the turntable, the constant changing is what makes tubing fun! You'll get it, just keep working at it. I don't think i'd pre-heat that thin of tubing, but when you start your puddle you could move it up a half inch or so and then move back to the start to give it a little "jump start" before you start adding filler. The top weld is hot(but at least consistent), the bottom weld is too cold. I'd honestly keep practicing on flat butt joints until they are all super consistent. Then move to pipe...the only thing you're changing is the torch angle. One thing at time....

Some more of my welds.... The last pic is a clip that is part of a "jake brake" system on a Detroit...
When I opened this page only about the top quarter of that photo was visible and I thought it was a piece of braided fuel line.

Hers some of my efforts. If i can get half as good as you, id be happy..... for now ill keep practicing... Joe
Thanks guys. Here's one from this morning. No walking, this was freehand. Stainless. <a href="http://www.flickr.com/photos/browndogwelding/8258471077/" title="Freehand stainless. #sundayschool by Brown Dog Welding, on Flickr"></a>
Made this today it's the top piece of a press plate to emboss sheet metal in the hydraulic press.. Posted from the TJJ App for iPhone & iPad
jdustu......is the pic just screwin with me....or are you making the weld get more "compressed" as you go??? No matter what......keep posting welds we all should strive for, thank you.
It's just the perspective of the picture. The weld remains the same width, it's just going up and around the joint between a piece of tube or rod and a flat plate. I think it's that bright spot that screws up the focus and makes it look funky.
Yeah....it's perspective, shape, and lighting. The weld is the same profile from start to finish around the pipe.
No walking on this one either, freehand. Mild steel. Freehand weave. Sunday Morning Service. #weldology by Brown Dog Welding, on Flickr
