A company I've worked for would use 316 rods used in the industry for the steel to stainless mix of materials for years without any problems, in fact the company would only purchase 316 rods to ensure that these were being used for this. Makes me wonder how much of a difference it really makes, I'll have to have an experiment with different ones myself.. thanks for the video, very interesting.
Mr Tig I work as a fabricator and I use a lot of 312 to join Stellite 6 tips onto S1040 shear blade bodies. It is the one recommended by a welding supply house, and it works very well. By the way these shear blades go from normal atmospheric temperature to about 1200 degrees Centigrade in about 5 seconds, and they last for hundreds of cuts before the Stellite starts to crack.
Few things worth noting: ER309 will give the most close match chemistry and temperature resistance to the 304 when welding to Carbon steel (to up the Cr and Ni for the added dilution of the Carbon steel), and is the logical choice here. ER312 has a higher ferrite content, which provides the crack resistance, but should not be used at higher temperatures and is more expensive. I'd only use this if the Carbon steel was a free machining grade or high Carbon and prone to cracking (or if that was all I had...). I'm not sure why ER310 is on this list, it is fully austenitic and prone to cracking, and really only there for the higher temperatures, above the service temperature of 304 or Carbon steel. If ER310 is necessary, the base metals would need to be 310 as well.
Thank you, somebody else said it. Aerospace consulting for NASA is appearently on this guy's resume. I'm all for free education, but not when it's bad.
Good Video, what were the thicknesses of the two base metals? Also i am still struggling with getting a good lap joint and also tee joints. Could you do a video on these? THX
I was looking at this for a 303 stainless cold air box. I need to weld the open bottom stainless box to the mild steel fender...I don't need much strength at all, but I want the weld to look nice and I definitely need a filler that will wet out. Any suggestions? Thanks in advance!
What happens to mild steel if I'd attach (weld or clamp) stainless exhaust pipe to mild steel one? Will that mild steel rust away faster than it would on it's own because of electrochemical reaction or what should I expect? I suppose what I'm asking is: Can I attach stainless cat-back system to mild steel pipe, or will it just rust from that joint very fast?
I notice in the close ups you're pulling the rod out of the shielding gas envelope. You should keep the hot tip of that filler rod shielded, especially with stainless. Maybe you'll respond to that rather then one of your cronies.
Mr Tig I'm currently in welding school. This was an awesome video and am looking forward to more of your video's. I do have a question about a certain metal. We don't have the ability to obtain Nickle-Copper. Are there any tips or tricks of the trade for that type of material?
I learned something cool, thanks Mr.Tig. Is there a paper copy or a site I can print off that cross reference chart by chance? Thad be handy I think. One more thing if you don't mind, can you do the same (I'm assuming) with a stick electrode? As in stick welding steel to stainless? Any idea? Thanks man for the lesson keep up the good work. -Pidge
There's a link to the chart in the description. You can do the same thing with stick welding and Bob Moffatt actually just shot a video on this subject for the MIG Monday series. It will be coming out soon.
I wish you guys would always show a close up of the finished weld, way to often you show the tinted view while welding and maybe a far away view of the finished part but not a close up of the cleaned up finished part, Mr. Tig and Bob Moffatt are both guilty of this.
Hi Mr Tig, I don't mean this in a patronising comment or deffo not a keyboard warrior comment. I'd just like to know what experience you have? As you understand you don't want to believe everything you believe on the Web. ps I don't doubt your tig talent I can see that in your videos. I look forward to you letting me know what you've done to get where you are. Kind regards David Morland
Currently, Wyatt does mostly consulting, but is also one of the track side welders at the Indy 500, MotoGP, and countless Nascar races. He also consults with Lincoln Electric in the creation and testing of many of their welders. Previously he worked extensively in aerospace for NASA as a welding engineer on the Apollo missions and worked for Lockheed Martin in their missiles and fire control welding department. Thanks for your question. Hopefully that addresses some of your questions regarding his background and knowledge of the TIG welding industry.

Really would like to see the welds close up.. Also the back sides of the material / welds..
Thaks for your vídeos Mr. TIG... I learn very much whit them!! grettings from México.
After mig welding all day that was so peaceful to watch lol
Could I MIG weld a piece of stainless to mild steel ?

The link to the chart doesn't work. It says the link is outdated...fyi
You guys need to make an app for that cross reference chart. All the other suck.
How can you run 77amps on material that thin? If I run 50amps on 16g it’ll
Blow through fast if I don’t move quick

The chart is a good reference and beneficial. The rest of this not so much. Keep postin

You'll see some benefit with a 75/25 Ar/He shielding gas. 50/50 or even 100% Helium would be better, although more expensive.

say can Yall
tig stainless steel pipe that would b great n awesome
Already on the list.
+Weld.com thank u cant wait
RIP MR TIG
Why didn’t you show us your weld, you always do.
Language in Tamil teaching in tic welding pls
saying most is not ok. :) austenitic stainless steel are non magnetic

Impressive. Thanks for your reply.
