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...
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...
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.
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.
It was so nice to actually have a final answer with C25. My shop does a ton of stainless, and TIG is usually overkill and takes forever - had a job for a radar mount and it took weeks for TIG, it was a miserable experience... Always have C25 around though for the general work, and tons of 316 filler wire (Cheapest TIG filler rod you'll ever find, is MIG wire ;) ) Time = Money! But Trimix is hard to come by in my area.
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
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.
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.
id love to have this guy as my instructor!! he seems easy to talk to and seems very knowledgeable very hard to find an instructor with both those qualities
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 :)
Always great videos. I've learned a lot about MIG welding. I have been a TIG welder for many years but not much MIG. Thanks again. I would like to see spray welding sometime.
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.
Very intresting! There are a lot of "world Champions" making coments. There is always something to learn! Thanks for good videos! Greatings from Sweden.
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'd really enjoy seeing a strength or ductility test of this vs with trimix, as well as corrosion (just leave them outside next to each other for a month or something).
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.
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
Dont you ever ask the teacher any questions if you are unsure about something? I would ask him how the weld turns out (or if it even works) if i use X gas vs Y gas. So yeah, i feel i have a legitimate question even if you think its stupid because you know more than the teacher and never need to ask a question.
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 UA-cam, 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.
I always watch any videos that I feel can be informative. sometimes just watching arc shots before a test can calm me down. I would like to see a video on backfeeding tig on pipe. that's something I need help with for sure. or a stainless to carbon tig video
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
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
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.
G'day Bob , Great video mate i always learn something from you guys over there knowledge is priceless !! Congrats on the boys giving you a shout on the WT & T podcast . Thanks mate. Cheers Troy
Hey Bob , it was episode 11 Alex Brown [ @cavemanwelder instagram ] mentions you helping out with some questions he had . Ive been checking some of his work and it is awesome.
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.
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!
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.
Great video Bob, I didn't think you could use C25 on Stainless. Other than color of the weld bead will the finished product retain the stainless properties as far as not rusting?
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?
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.
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.
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.
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 ?)
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.
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.
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
i was welding today first time steinless with mig but with another mix. 98% argon and 2% CO2. in germany this gas is name Cornigon.i cant find any video about this mix.
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
Good stuff. I’m using a 309L Si with 98/2 oxygen to overlay steel. I’m getting a dark scale on the weld. How can I eliminate or at least minimize this? Thanks
I doubt you can, you are in the axial spray transfer mode I assume....just wire brush off with a power stainless wire wheel or used a chemical made to passivate the weld....Paul from weld.com
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.
you can, but it will be very hard to do, and look terrible, and may not even bond...it needs the co2 to help wet out the puddle......Paul from weld.com
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!
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 😎👍
Armchair welders, you got them in every field, looks like a fine job to me. As long as you have strength. I believe you are certified!! Opinions are like A_ _ Holes every body got one and some talk out theirs!!

Great job Bob! Your the man!
Great video Bob, I didn't think you could use C25 on Stainless. Other than color of the weld bead will the finished product retain the stainless properties as far as not rusting?
If you don’t introduce an oxidizing component or oxidizing contamination it will just be stainless...
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.
Does it works with 100%argon??
No 👎

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 ?)
Excellent information. Exactly what I needed to know. Will the world end if I used C25 on stainless.. probs not :)
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.
I was given 90%/5%/5% (AR/CO2/O2) in place of 75%/25% (AR/CO2). Is this an acceptable substitute for 'general' steel MIG applications?
Point of shielding gas is to keep the O2 away from the weld.
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.
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.
@@megasaxonzro9451 the main purpose of the shielding gas is to keep the nitrogen away.

How's the penetration of stainless with c25 gas? Is it compromised?
it will probably be less than he/ar/co2 90-7.5-2.5 due to the heat of the he. Paul from weld.com

Does it work with 100% CO2?
No. Welds gonna be brittle and lose all of its corrosion resistance.
