Whoa, whoa, a video without a clickbait title, where the host gives us the 'TL;DR' answer to the video's central question in the first thirty seconds?!? Unheard of! That earned you an instant subscription. And since I'm another non-pro (about $40/hr according to your video! ;D ) who also wants (like half the other commenters) to do GMAW as cheaply as I can and still get acceptable penetration + cosmetics, this piece was crucial for me! I literally just now came looking for this before trying to do a weld on a part I'd rather not replace...

Most people have no concept of class in this country anymore. Love your videos; they’ve been a tremendous help.

Don't listen to the garbage people love to talk crap online that they know better or do better but couldn't your a great welder who I have learnt alot from watching you over the years

Don't ever apologize for being you.. Comments are just opinions usually given by people who have zero experience other than what they make up... I came here because I'm a novice with my welding skills and needed to weld up my stainless exhaust... Your excellent video just gave me the information I need to at least know its possible and now I will go do a bunch of practice welds on the old stainless pipes... Prep is key...

This weld was not ever meant to come out pretty just meant to come out functional. He gets one comment that asked why a weld was peaked and his day was ruined. Thanks for all the great video some day i hope to be able to weld as good as you.

Very good information. I'm a novice welder, and I get into a lot of different weld projects. This information is really good to know and helps. Thank you for your videos, I really enjoy them and find them useful.

You all do great videos and informative topics. Many of us appreciate your instructions .

Thanks for such an informative video. You saved me from having to ask those who think they know, but really don’t

Your ss mig videos have reassured me after I was given lots of stainless work to do an it made me feel like I couldn't set my machine, but it turns out I can haha. Thanks very much

Always the keyboard experts with the nit picking comments. Every forum. Every video. Thanks for the video. Recently picked up a Miller and am teaching myself to weld with your help. Gonna try and modify my Harley handlebars soon. They are stainless. All I have is Ar/CO2. I doubt I will do that much stainless in the future so this video is spot on helpful.

Great video. I was wondering about c25 and stainless. You're doing great work. Thanks!

I think the videos you show us are very educational. As far as people commenting, let's see some pictures of some of their welds. We're not welding dollhouses together. Spatter is sometimes impossible to control. That;s why God made spatter spray and grinders. Keep up the great work Bob. Thank you for all your knowledge.

Very well articulated. This is exactly this information I was searching for. Thank you for sharing your knowledge 🫡

Great video showing us weekend warriors how to get by with the things we have on hand, I love these types of videos. I had this exact same question as I have a roll of stainless wire but only C25 gas.

I like how you include the welding sound in your videos. It seems to be an important part of the learning and improvement process with welding. I'd love to see a video that focuses on the sounds - eg how to recognise when a weld sounds good or bad in given conditions...

I love this channel but Bob is my favorite guy to watch old school guy with a lot of knowledge great dude!!!

Thanks for another great video Bob. Good info to have.

I had to weld some ss to cs at my old job and we used 90/10. It was a 1” block of ss that gets machined so I just cranked it to 25/500. Using 309 , man it looked beautiful. Super easy. Thanks for video again.

Don't worry about the negative comments mate, everyone reckons their welds are better than the next guys on the internet lol. Great channel with some awesome information and a lot of effort into each video, cheers for helping me learn :)

Great video,I learn something every monday.

Great video!! I’m going to grab a roll of stainless wire just for doing little repairs like you mentioned. It’s nice to know that my C25 can get the job done in a pinch. Honestly had no idea you could make it look that good with C25 for a fast far repair or a small little job to keep things up and running this would be great!

Very intresting! There are a lot of "world Champions" making coments. There is always something to learn! Thanks for good videos! Greatings from Sweden.

Knowing how to weld and making videos have nothing to do with each other. I’ve been doing this since 1973, and I dare say that I know what I’m doing, but I’m not interested in making money off KZread, so I don’t make videos. Sometimes I learn something from the videos I watch, sometimes I can contribute to them, and sometimes I disagree with something I see. Nothing wrong with that. It’s how you say it.

Thank you!

I have adjustable crater fill on my oxford imig pulsed mig plant, it's really good for building up the end of the weld..

Hi Bob-another great video! 3 questions-1)The steel looks "as received" don't you clean the edges of the metal with abrasive or solvent? 2) I see one comment from part 1 where the question is "doesn't the weld get less stainless because of carbon pick-up from the C25 " but doesn't the trimix do the same? 3) Doesn't the helium increase the arc voltage and that is why the bead profile is different ? Hope you make sense of these questions.Best regards, Steve.

Amazing video Bob. Do you cut the coupons to check for penetration and impurities

Great videos! Just came across your series. Any tips or considerations for MIG welding 316 SST? I plan on using TriMix and 0.035" 316 wire....lots of 11 ga. square tubing. Thanks!

Thanks for this, I live in New Zealand and we cant get Tri Mi here, this will get me out of trouble with a stainless 304 exhaust im working on

Like most hobbyists 99% of my welding is carbon steel but I might want to use stainless for small jobs on my boat. Buying a bottle of tri-mix just for occasional jobs is not an option. Who cares if I have to spend more time on cleaning? Thanks for the video.

I heard that mig stainless with c-25 gas partially changes the stainless properties, ? and that tri- blend is not only better looking weld but doesn't change the stainless properties? Great Video thanks William Orange county, ca

THANK YOU SO MUCH FOR THIS. I was looking for an example of this for a while. I've also heard C25 can be used to get better results with flux core SS wire? I see in autoplay you have a video already for SS FCAW, so perhaps you address it there

Hey Mr Bob. I watch led your segment on Stainless MiG. Most Manufacturers say to use TRI MIX gas. I found a .30 stainless wire from US Forge 308L and they recommend using C25 (75%Arg/25%co2) is it just this particular wire or is all wire the same??

You're my idol mate

After you weld the other side, cross section, polish and etch the two welds to show penetration. I'm interested to see the difference.

Excellent information. Exactly what I needed to know. Will the world end if I used C25 on stainless.. probs not :)

Can you mig weld stainless with 100% argon? If i had only 100argon and 75/25 mix what would you suggest?

I don’t have a clue how you got the puddle to wet that well. I’ve been trying to get this setup to work for the past few hours with nothing but failure.

Hello Bob, thanks for showing me that I can do stainless with C25 gas. This is the only gas I have currently because I mainly do carbon steel welding. My machine is a Hobart Handler 190 with 240 AC input. Obviously I’m limited with this smaller machine to only short circuit method, and from what I understand C25 can’t do spray transfer even if I had the heat. Question: are there any other metals besides carbon steel and stainless that C25 can weld ok? Also, why do you pull back at end of your weld to fill the crater instead of letting off the trigger & zapping it again to fill the crater? Have I been terminating my welds incorrectly all these years? Thank you sir 😎👍

I found at my last job we had some welds get eaten out by chemical in washers. This could have been from the c25 on one of the welders I found, or maybe one of the guys used regular steel wire. I remember reading the the carbon from the gas bonds with the metal and is then not as chemical resistant. Any thoughts on that? I'm looking into this for welding SS at home.

I think those kinds of questions are super important and you shouldn't take it personally. Knowing that that's a normal feature could prevent someone from wasting time trying to get their welds to lay flat the way they do with mild steel. I believe it's more of a characteristic of stainless, stainless is a austenitic steel so it's crystalline like a hardened steel, and may take more heat input and react to it differently

I wasn't aware that you should use a try blend for stainless steel MIG. Well that made me wonder if stainless steel flux core would sound the same as mild steel flux core.

FCAW stainless with C 25 welds AWESOME!!!!!

Hi everybody, for my experience what you did is good for a strictly welding point but is not for a metallurgy one. Welding stainless with CO2 mix gasses make the joint good and strong but it will got corrosion issues, especially pitting rust will come out soon. Stainless steel, especially the 316, has got chromium and molybdenum that need to make a pure thin layer in order to protect the inner metal from corrosion. Using an oxidating gas mix like the C25 the alloy is not able to make that layer and so you will obtain a joint without the most needed feature of stainless: the corrosion resistance.

Good video. I was wondering if you could make a 6g vid, uphill and one downhill? Like you did with 5g, that also shows your body positioning. I know that's a lot to ask. Thank you

The carbon from the CO2 will get in the weld and it will grab the chrome molecules and that area will lose the stainless properties.

Hi Bob, aside from the difference in appearance of the welds between the 2 gas options: is Tri-Blend superior structurally to C25? My application in mind is stainless steel exhaust piping which sees massive vibrations, flexing and temperature fluctuations. Thanks!

Damn! I just went and got a tiny bottle of trimix for $400 just to weld 5” of stainless when I have C25 at home. It’s for a restaurant so I figured I might as well do it right in case a year from now it rusts and I have to do it again.

If you have to... C25 or flux core for stainless. I know there are not the best options... But what would you choose and why? Greetings from Chile.

hi Bob I did some repair in MacDonald restaurant as you know everything in the kitchen is stainless steel I were told that I could weld with the 25/75 gas but it may get rust because of a it so I bought a trimix gas by the way is very expensive but it did an excellent job I notice that spark a lot and it make a weird noise while I was welding I believe is OK to use 25/75 gas but is recommend to use a trimix gas to do the job well done beside I want to be call again when they need me I make 450 DLS in less than 3 hours please make a comment thanks

Short circuit stainless will always have some type of peak. If you want it flat then you need to get into spray mode.

How about a 75-25 gas with a flux core shielded stainless wire ? How would that work ? I went to purchase tri mix and almost passed out when they told me the cost (i guess there’s a helium shortage ?)

Is C25 gas works on Pulse Mig too? instead of using C10 gas?

I'm told by other mechanics at my work to just use regular wire on stainless, mostly 304, and I know it's not a good idea. Besides losing the stainless properties what happens to the structure of the weld?

@kmccurdy21

birdfighter0307 when you say regular wire I assume you mean carbon steel. If you weld stainless with carbon steel wire the weld will be brittle due to the drop of chromium content in where the two different metals meet. The chromium and nickel content drop into the hardenable range.

At one time I worked for Crane Freuhauf trailers they used 5% co2 on all mild steel and stainless steel mig welding. The gas was piped around the factory so they did not want multiple mix's so it was just 95/5 and 100% argon available.

@YouloveTj

7 жыл бұрын

Yes, this is a very common gas mixture in both the U.K. and Australia. The oxygen content causes the weld pool to have less surface tension, causing it to "wet out" more, creating a flatter profile. Generally oxygen consists of 2-5% of the gas mixture with varying amounts of CO2 and argon; with a higher CO2 percentage for thicker sections. This produces x-ray quality welds on mild and carbon steels but does, however, leave a heavy surface oxide on stainless steels, similar to the one shown in this video - which requires an extensive amount of pickling paste in order to achieve a bright shiny finish.
