Chrome moly vs dom

I have heard that aircraft manufacturers mig weld it too but it isn't done by Boo Boo with his 110 buzz box. Tig welding lets you back the heat off on outside areas and put more to inside joints. You've got a lot more control over it. All pro level 4130 drag cars are tig welded without exception. Whatever works though.

wow, how did you know my name was boo boo? how ever i use a millermatic 200 with a flow meter to control my 75/25 argon. i have used tig and mig and if your joint, and not the one your smoking, is properly fitted , i prefer the mig, but if all you know how to do is braze, then tig would be better

Nobody said that you were the Boo Boo, but... As long as the person welding the car up is also driving it have at it. If you're building chassis for other people to drive and they're putting their lives in your hands you have an obligation to do it right. Mig is a whole lot easier and faster and works fine on mild steel. Tig is much more difficult on a chassis because you're welding overhead and out of position a lot of the time but if you're actually qualified to be building chassis it's the way to go with 4130. Yes, I can do both. Educate yourself. Good luck.

where do you get this so called qualification your talking about, is it some sort of certificate or some thing? ive been in some of the biggest and well known shops around and ive yet to see any

I guarantee you that you've never been in a shop building pro drag cars and mig welding 4130. A simple call to NHRA would let you know that you can't do it and certify the chassis. My info is firsthand. As far as working in pro level shops, you truly have no idea. Again, educate yourself and then post on the subject. No hard feelings, if you don't know you don't know.

90% of people on here ,including you, have probably never held a mig or a tig, and as for your dragracing statement , thats why i quit fooling with that BS a long time ago, ive welded nearly every thing known to man over the last 30 yrs, but you dont have to believe me thats your right, no hard feelings here either, have a good day

Like I said, make the call. I could make you look real ignorant right now but I'm not into whizzing contests. Pride and stupidity are found together, and you're hurling personal insults at someone you know nothing about. I have the credentials but I'm not interested in putting a resume on the internet.

i could make the same reference to you, and like the famous forest gumps mama said " stupid is as stupid does" take it any way you want, the end.......

Everything I said was 100% accurate and can be confirmed with even minimal effort. The type of rod, shielding gas, and procedure is what is used in pro chassis shops. NHRA, SFI, and now circle track chassis builders agree that it should be tig welded. You however are more brilliant than than the people who have been building hundreds of cars, structural engineers, and the people doing the testing because you have a Millermatic and a Flow Meter. Big deal who doesn't have one. If you look at your super duper spool it's probably ER70-S2 wire, maybe ER70-S6. You just can't control the heat as easily. Go back to beating tubes with a hammer for testing. I don't know where some of you people come from, but I've never seen a forum like this where people don't want correct information.

How does Rocket weld their moly cars? i know it is mig welded, but do they stress relieve it?

Oh. I'm a fool. This comes from a guy that quotes Forrest Gump, can't spell or use correct grammar, and has contributed nothing constructive to the thread. I provided information about filler rod, shielding gas, and how it's done in a pro level chassis shop. The smarter people on here have already checked it out and confirmed it so it'll just be natural selection from here. You haven't even mentioned what magic wire you use so you're just making noise.

LETS GET READY TO RUMBLE.... and the gloves come off...

[twisterf5]

this is why i stopped posting / i could post my magic wire LOL but you can get it at any welding supply store ( but most do not stock it but will order it for about 15 bucks a pound. but here's a fun fact have 287 wins 9 champion ships all in our own chassis so i guess i will stay with that works. now guys that my stats that you can google my name to confirm LOL richard clew . now you guys play nice

Why not post it? If it's a good way to do it maybe it'll keep people from getting hurt.
