Wanted to show you guys/ get some input on my welds. I bought my first Tig machine (diversion 165) a week ago. Been welding for about 4 days. Check them out.

 

And heres the back side of the welds. I forgot to mention this is on .090" Aluminum. Which i think is 11 guage not sure tho.

 

You don't want burn thru. Either you're going too slow or you're using too much heat.

 

Your speed looks ok, but practice more on the heat than the look of the weld... What really helped me was the angle of the torch and pedal control. N E Way you will get better with repetition and patience LOL

 

Ok what would you set the amps on ? it's .090 thickness. I know I have got a lot to learn and practice but how do you think they look. Foe only welding 4 times

 

Im a little confused about the burn threw arent the welds suspost to penatrate threw to the back side or not with aluminum ?

 

I would suggest starting out with mild steel... can't understand why everyone who has a welder which works on AC starts with aluminium... it's much more difficult then mild steel. I would suggest get 1/8" and 3/32" mild steel plates, start out with them, when your ok, go to stainless steel, and only then aluminium. At least that how I would do it if I would have and AC welder...

Good luck

 

I agree, aluminum burns fast and is hard to practice with if you are a noob..

 

Unfortunatly I have a bunch of aluminum here that I figured I would learn on and it would get it out of my house. Kind of a win win lol. Any advise on the aluminum welds what i'm doing right or wrong for that matter

 

I started with aluminum and i think it helps to be honest. With steel you dont get a feel for heat. If you're too hot with steel it turns gray and looks poopy. If you're too hot with aluminum you burn through. So it teaches heat control really well. Lookin good.

 

The burn threw everyone talks about arent i suspot to have peneration on the back side ?

 

No. Burn thru is over penetration. You should never have it. The only thing you should see on that side of the metal is discoloring from the heat. Just turn down your heat and keep practicing.

 

Ok, thanks. I'm obviously real new to welding. I'm confused though because I've seen pictures on here and real life stuff such as manifolds, exhausts, IC piping, where if you look inside the pipe or the manifold, you can see the welds especially on a stainless manifold you can see them inside on the back side of the weld. Is that different than aluminum? Thanks again for all your help. I'm just starting out trying to learn and make sure I learn correctly

 

start with steel aluminum will follow

 

Yeah you diffidently have to much heat, but honestly for it to be 4 days worth of practice I would say it is alright. Start trying to weld joints butt welds and t joints will teach you a lot.

 

Aluminum is perfectly fine to start out on, it's all about torch time. Some weldments require 100% penetration and other do not. When your welding on a flat plate you want it to penetrate but not burn all the way through. Hope that helps.

 

ya it's only my 4th day I will turn the heat down and take some more pics. I actually welded a bunch that neverd burned threw and I thought I was wrong becuase I saw no penertration. lol I will turn the heat down and try again. I wanna start welding peices together i have to get some more aluminum. Thanks for all the help. Keep an eye out for some more pics.

 

Agreed, starting out with aluminum is fine. I did, And I also agree theres to much heat, but they look decent for only 4 days. keep it up it will come.

 

I started out on AL too. Actually had a hell of a time adjusting to steel until I figured it all out.

Do yourself a favor and start cutting all of that aluminum up and start making T joints and practice welding pieces together. You will learn a lot more about heat control this way than doing it on plate.

It's all about torch time now and trying out different things.
