A little tig welding advise needed

and if he shows up with a spool gun on a mig welder send his ass packin .

you need tig welded.

seen a guy pull a tranny and get the bellhousing welded up and 1 week later back again as the spool gun weld broke same spot. i took it up the road and had it tig welded . still going to this day as far as i know.
 
Brett may i ask why the spool gun method does not work?? I thought about a spool gun setup for my mig for doing aluminum, but i wont if its junk
 
light sheet metal or other prob fine.

but thay dont get the HEAT out like a tig for real work. and with aluminum you need lots of ASS behind the heat as it disipates it real quick so keeping the area hot takes a lot.

Its fuses the weld better with a more intense, consistant heat and can help keep the metal around it from warping. It creates a better puddle. The only thing I have ever seen a spool gun used for is aluminum irrigation pipe and even then its a mess compared to good tig welding.
 
Ok , got a nice chunk of aluminum welded onto it today, but, what are your thoughts on drilling a hole straight through the new aluminum, and just running a through bolt, with nut and washer, opposed to the drill and tap method? Would there be any benefit with tap vs a through bolt?

If you can file the back nice and flat and perpendicular to the hole, nothing wrong with that.
By the way, I should be going tomorrow, I don't know where yet, I will know in the morning, but no matter where I am going I can make the trip for you shorter so you can meet me and grab the adapter.
 
I would think that if you smoothed the back side flat like imiceman44 said, a bolt with a nut on the back side would provide more clamping force. And I never much cared for taping aluminum, most of my automatics have at least one heli-coil and the last one I rebuild I just went ahead and heli-coiled all four.
 
Whell, it turns out that,UPON FURTHER INSPECTION, there wasn't enough room for the welder to get in there and form enough metal, so it looks like, after all that,,,I'm yanking the transmission so he can get on top of it and do a proper repair. I'm thinking about changing tourqe converters and mabey some small affordable upgrading while I'm at it. Its falling deeper and deeper into the black hole lol.
