yeah well this is one thing i have never done. mixing metals. well i ran into a situation yesterday with my wheel studs... the lug nut is stuck on one of them and the stud is spinning... I tried clamping it and all. The last resort I'm thinking of is to tig weld it but wasn't sure because like i said i have never mixed metals before. what do you all think. and what filler wire shall i use?.... the studs are from H&R... are they aluminum? not quite sure.. any help would greatly appreciated. welding shops are closed on weekends near me. WTF.

 

Won't work. The only thing that can weld aluminum and steel is explosion welding.

 

Your wheel studs are not aluminum.

 

^ x2. Probably plated steel or galvanized steel.

 

just tack the stud to the hub,if i'm understanding your problem correctly.the studs are steel.

u could prep the area before u do it , but how would u get to it.
oh, and don't breathe in the smoke (plating or galv).

 

I know aluminum is out of the subject now, but
adhesive bonding is another application that can join dissimilar metals
(falls under "welding" in most books;its just not arc welding).

 

thanks guys... guess i gotta get in there to prep the area first.. thanks guys. yeah the studs got a platting on them. or painted. dunno. it will most deff be a BITCH.

 

i have had this problem before i owned a shop , i had to buy a dremel and a bit used for cutting Stainless, it took for ever but i cut the nut on one side and hammered it off. now a days i just use a torch, or air hammer with a sharp bit to splitt the nut.

 

tacked it wit my mig... everything is fine.. thanks.
