I wanted to practice on some .063 x 3" aluminum tube, so rather than cutting short pieces I decided to make pie cuts. After making 2 90's I went a step further and made a ram's head. Then a couple of saddle cuts into a cross, on to 3 more 90's of different radii. Then what the heck, put them all together. Man, did I learn a lot, like how to fill holes and the criticality of torch angle, and so much more.

Thanks Aren and Shaun. What I found that helped most was lowering the start amps from 50 to 25/30. I obviously need to work on my foot petal amp control.

Really looking forward to this project series. Maybe you could share a brief description of the work flow to help us understand what we will see in the next videos. Great job on the safe landing of the boat.

You are so right. I bought an Optrel about a year ago and they are a game changer. They are a little pricey, but if you can swing it I highly recommend them.

I'm doing some 1/8" 5052 & 6061 aluminum but welds and they are cracking at the beginning of the weld. I've been able to minimize the cracking, but not eliminate it. I know the cracking is caused by heat/cooling cycle, but I could use any help I can get to eliminate this problem.

Commented on 2 inch TIG Socket Weld in Tripod Vise

25 Sep 13:18

Like you in the very distant past I made a lot of these welds. I never had an issue with making the fillet full size, bringing the weld to the edge of the socket. You just have to be careful not to over heat the material. I found the biggest issue for most inspectors was the amount of expansion space at the bottom of the pipe in the socket. This space was usually defined by the design engineer or by applicable code. Lacking any definition a good rule of thumb is about an 1/8”.
