I'll need an aluminum BOV flange welded to a 2.5" 2mm thick piece of intercooler piping, after I get to the point of test fitting everything in the next few weeks. Would anyone know of a shop or individual somewhere in the NW burbs or intown who is comfortable welding aluminum and that would do this for a reasonable rate?
There is a shop called Mckellco in Alpharetta. The guy there Steve is amazing. He has done plenty of aluminum bov flanges. Talk cash. Probably about $35-45 bucks Mckellco Inc 735a Branch Dr Ste A Alpharetta, GA 30004-7719 (770) 475-0421
nicad doesn't have a machine at home to weld aluminum :unamused: here's two things I welded up for ped recently: his intercooler charge pipe meth hole and wideband o2 bung in his downpipe http://www.justingarrison.net/images/subaru/pedschargepipe.jpg http://www.justingarrison.net/images/subaru/pedsdownpipe.jpg edit: I will be selling my miller welder (Basically the best company in the world for welding) sometime soon if anyone is interested
Brandon at Battleground does a great job with a tig. Buy Nicad's welder, Miller Maxstar 200. Matt, can do it also.
yah. does DC TIG, pulsed TIG, stick welding, high frequency starts, pulse controls, pre/post flow adjustments. weighs 37lbs, and can be run from single phase 120V. it's a badass welder
If I didn't have my AC/DC, I'd buy in a heartbeat. I'll check with some pipefitters here, they might be interested. Send me an asking price for it.
Thanks Matt! I may also need more welds on the IC piping. I'll know more in a few weeks after I get the engine back in the car.
That's good to hear. My friend and mentor who's working with me on the Legacy fabricates steel roll-cages and suspension stuff for rock crawlers like a madman, but he isn't set up to do aluminum. Is transitioning to from steel to aluminum difficult?
Yes. Aluminum is very soft and is like water when you try to weld it. It also requires a very different type of welder than steel.
takes a little bit more current, and the weld puddle looks different. you have to wait for the puddle to form and strip the aluminum oxide layer off before adding filler (otherwise the weld will be contaminated). the process is essentially the same, however. you just have to use an AC machine (either MIG or TIG) and using a slightly different tungsten for best results.
pure tungsten for AL, 2% thoriated for steel, ceriated for both AL and Steel and is not mildly radioactive like thoriated. Walk through an airport with that in your pocket
heh. when I used to run control point watch for reactor compartment entries on a submarine , the welders would always come in with thoriated tungsten rods. it would set off the friskers and geiger-counters when they would perform their body frisk upon exit. it is mildy radioactive, somewhere in the neighborhood of 200 ccpm>background not as cool as hitting bongs of activated Argon-41 and drinking primary coolant, though
For a good AC/DC TIG, around $2K. If interested PM me as this is my primary job, "propane and propane accessories"
