Steel - Welding 4130 Steel Tubing - Tig Welding Chromoly Up in Here Good morning. Now, I found out about Steel - Welding 4130 Steel Tubing - Tig Welding Chromoly Up in Here. Which is very helpful to me so you.

4130 Chromoly tubing is used for all kinds of applications, but 2 of the main ones are for airplanes and for racing just about whatever from motorcycles, to mountain bikes, to go-carts. What I said. It just isn't in conclusion that the real about Steel. You read this article for info on that wish to know is Steel. Steel Aisi 4130 tubing is strong. It's real strong. So the reckon it is so beloved among race car and airplane builders can use thinner tubing and that translates into speed and less weight. Welding 4130 steel tubing is not that hard. There seems to be some mystique colse to it but it actually welds good than plain carbon steel. So then whats all the fuss about?  Well there is one thing. If it cools too quickly, 4130 chromoly tubing will be hard and fragile in the heat affected zone of the weld. Thats the main thing to be implicated about. So how do you preclude the weld area from cooling too quickly? Make sure the ambient temperature is above 60 degrees F. Use a small propane torch to preheat weld area to about 100-150 F. 300 degrees F if room air is below 60 degrees. Weld a dinky bit slower than you would for plain carbon steel. Dont use 4130 tig welding rods. Use E70S2. Never speed cool anything. Some often asked questions about tig welding 4130 steel tubing are: Q. Do I need to heat treat the weld when I am done welding? A. No, the term heat treat is often misused. What is commonly meant when it comes to welding chromoly is "stress relief". A stress relief can be done with an oxyfuel torch and a 900 degree F temp stick or a digital pyrometer. But it is commonly unnecessary unless the thickness exceeds one eighth inch. Q. Do I need to back purge my Chromoly welds with argon gas? A. It always helps, but think about how many oxy acetylene welds there are out there doing fine that were done with no purge. Q. What about using 308 stainless for welding chromoly? A. There is a bunch of seminar on Baja Racing forums on this subject. I can tell you that lots of welders are using er308 tig welding rod with success, but for airplanes, E70S2 is the way to go.  One thing that might not occur to you that you should consider is that if you ever needed to weld repair something and all you had was a gas welding torch, the E70s2 would be actually welded over with an oxyfuel rig.  The 308 stainless welds? Not so much. I hope you receive new knowledge about Steel. Where you can put to use within your evryday life. And just remember, your reaction is passed about Steel. Read more..
