Default For you Welder Types: Welding 4130

I've been looking all over the net and haven't found a satisfactory answer.

Some say this crap has to be TIG welded.

Others say MIG is fine.

Both sides say you must have the proper filler wire.

Which is it? Just TIG, or Both?

4130 is pure steel (cromo) It will weld super nicer than anything you have ever welded before! The favorable method is TIG because of the heating/case hardening associated with other welding methods. Mig will be fine! You will want to do everything in 4130 after working with it but your wallet will keep you under control! There is a great place between Lafeyette and I-25 to get it. The place is called Aircraft Steel. Snoop it out and call first as the guy sells it out of his barn. He even has it in streamlined tube....very cool! You can buy it by the foot from him.

I'm just designing, cutting and notching

I am hoping to get you to do the welding there partner.

I am getting a second (or is it third) start on my steering. This time for real though.

Second question:

I just read that you can use mild steel filler wire for 4130. Is this true? Or should i get cromo wire?

Third question: Okay to weld cromo to mild steel? My heims are mild (i think), as are the tube inserts for the replacement TRE's.

You can weld it with the same equipment you have been welding with! I'll grab you a couple scraps Friday to play with. It really is just very clean steel in the way it welds. Cromo's biggest asset is it's memory! It's perfect for tie rods/sleeves and other things that can get hit as it bounces right back to its original shape (within' boundaries of course)!

most wire is 80kpsi compared to mild steel at 40kpsi. the main problem is the heat, and the haf. Tig is great if you have the machine. There is some specific heat treating that you should do to do it right. pre-heat and cool down to be specific. Check lincoln's site or miller/hobart's boards for articles.

If it's for a cage, do it right and heat it/cool it.

UB's right, it is very cool to work with.

Awesome Ian. That would be great too. I'll be in contact when stuff is ready to go, and see if we can fit it in sometime. No worries though, if it doesn't work out, as I'll just buy some wire for Drew's welder, and see if I can get him to do it.

Now, you like Sam Adams Cherry Wheat, right?

Here is the deal:

I've got a center link and tie rods that will be cromo. I have the whole thing designed and am working on a jig to hold everything in place during welding.

I have rod inserts for the tierods which are mild steel, so that I don't have to try and tap out the rods themselves.

Hopefully I won't be breaking my stupid steering anymore.

If you are still IFS (don't recall), your weak link will be the idler arm. You *should* be able to fab up a mighty strong replacement for it with a spare pitman and some backyard engineering!

Speaking with Hank of Hanksville Hot Rods (VERY cool NHRA certified cromo roll cages and etc.), he is of the 'TIG it!' school with cromo. YMMV.

The idler is what is going most of the time. It is getting replaced.

The trick there is getting it to clear the frame.

I haven't figured that part out yet. If I can't, I will just buy the bulletproof one from TC.
