View Full Version : Supercharger welding
02-18-2010, 03:21 PM
There's a huge debate on a Mustang Hot Rod forum. It's regarding a plate being welded into a supercharger on a Ford Mustang Cobra as a performance modification.
There's been a lot of debate as to the method or acceptability of the weld. I would be interested, as would thousands others, of your opinions...

It can be welded without failure. I'm not a metalurgist but I'd probably use 3003 aluminum and bow tie all my welds. If you dont know bowtie means to weld half the weld from one end to the center then other end to the center. Aluminum welds can crack when theres lack of penatration or lack of filler metal.

I read the article and i think the problem is the "sheet alum plate" thats pretty thin is flexing and breaking the weld or tearing the alum plus the exact content of the alum may not be known. If it had been thicker alum and welded all the way around i don't think there would be an issue. Even steel sheetmetal will crack if just welded with a small bead on something thats more soild. Saw it everyday in the mill with "tacked" parts. Just my thoughts...Bob

Another few points. We don't know the grade alum of the case or the sheet that was welded. We don't know the welding process or the wire type used. So without a few more what ifs the problem just may be a problem...Bob

The thread on this subject was 263 responses long. I read each and every one of them. I gave my opinion and signed it much the same as I do here only I left off my website. I was sent a PM from a Mod who told me he edited out my signature. His PM included and advertisement for the guy who's opinion I slightly differed with. Maybe they are better off in their own ignorance.
I sent the Mod a PM reply that I also put on the thread. I think I will be banned from there soon enough.

Thanks, guys. You've shed some light on this subject. I like to defer to people with experience.
