heat treating of suspension parts

[blitza]

ummmm, so here i go bursting into print,

If all you are doing is welding mild steel to mild steel, I wouldn't bother with stress relieving them, unless you distort them heaps (althou it would only cost you about $25 at heat treatments anyway)

If you are welding cromolly to, um anything then i would heat treat or it will crack. I made some braces for someone's 'track' car (it only ever ran on three...) out of cromo and mild steel, tacked everything on the car, then finished the welding on the bench, all was distorted to hell, but after 'normalizing' everything was back about where it should have been.

Suspension arms we made for a certain #1 datsun out of 4130 tube, tig'd, normalized, fitted, and then the wheelalignment guy put a mother of a load on them, and they're still fine.

If you got anything usefull out of that you're doing good. I'd just mig them.

as for normalising heat teh parts up till there cherry and then cover them in lime (i mean liek at least 100mm bigger that teh object in all directions) BTW for what you just did...mig is far better than tig...less heat issues and distortion

[Distrb]

did you get those struts from christchurch? on TM, if so i was wanting those and asked for the buynow but someone clicked b4 i did.

no he didnt

[Mr Revhead]

yeah got them local.

mig has crossed my mind due to ease of it. it maybe that using actually getting a tig in there isnt practical

tomorow is cutting and measuring day, so ill know then!

Shouldn't that be the other way round???

[Mr Revhead]

actually no, i need to cut the donor arm up to measure the donor section so i can calculate the length i cut the ke70 arm too
