First T Joint on Aluminum

admin

It has been awhile since I introduced myself. I signed up for a TIG class at the local Community College.The instructors were nice enough to let me sign up for the course and basically gave me an independent study option. Since I am doing this to work on my old cars and some general light fab work I have been welding chrome molly tube, and carbon steel tube. I passed my code inspection and bend tests on those last week and I finally got to some aluminum today. Let me know what you think.

Reply:Not that bad. The area circled in green looks real close to what I'd be looking for. The area in red needed more filler. The beginning has a lot of consistency issues that need to be worked on.I can't tell in that pict if you brushed the material or not. I see a lot of black in the weld that usually comes from contamination. My 1st thoughts would either be poor material prep, or a dirty tungsten.It also helps if you list material and filler size, machine you are using and amps etc so we have all the pertinent info. The material looks thick in the pict, but I'm guessing that's an optical illusion..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
