How to TIG Weld Stainless Steel Exhaust Pipe | Everlast Welders 

Tell us what videos you want to see on the channel here 👇

There are so many hack welding videos on this site that it's super refreshing to see one like this where it's done right and also demonstrates what happens when it's done wrong.

To take the back purge a step further, I'd suggest sealing the end plugs tight with ductape (you could even dispense with the balled up foil and just use ductape to close off the ends) then put a pinhole in the end opposite the gas inlet side and adjust the inlet gas flow for a steady gentle outward flow at the outlet side, which would insure a steady gentle outflow at the weld gap as well. If you use the balled up foil for a plug you could still wedge a small piece of 3/16" brake tubing etc in the opposite end, the idea is to have a controlled and verifiable end-to-end gas flow, not just random leakage at both plugs, the inlet side should be completely sealed and the outlet side should have controlled outflow, insuring the center weld zone is covered with gas. Give it a couple minutes of flow time to purge, then weld while flow is steady.

Super simple and informative! Would like to see more demos like this in the future! Weldgreen!

“Weld mean weld green” I have always wanted an Everlast welder, would look awesome in my garage!

I bought an Everlast 210EXT maybe a month ago and I love it thanks guys. Up next will be a water cooler. I'm glad to see you're putting out new content maybe soon I'll be good enough to do some videos for you.

Weld tube sent me. Looks vary informitive, ready to learn something new. And I did. Foil ingenious. Thank you

Great clear to the point lesson with excellent demo. Thank you

I bought one of what might have been one of your earliest multi-function machines (TIG/Stick/Plasma) about a dozen or more years ago! Still have it - still love it. :)

Awesome video! Thanks Unobtainium & Everlast 🤘

"Reynolds Caps" Should be a trade name. Saved the bacon many times! Nice video!

Weld mean weld green. My everlast welder was stolen and I’m out of work from the covid pandemic. Hoping to save enough from side work to buy another. Everlast last welder are the best there is period. This company has helped me feed my family for years!

Really great video. Thank you so much for making it!

Very nice. Been a fan of you for a while now.

Weld mean weld green! Great vid. Keep it up!

I bought the Everlast 256i.... nice machine, good service from techs.

Weld mean weld green. My husband would absolutely LOVE this.

Can’t wait to try out this beast 🤞🏽🤞🏽🤞🏽

I own Wheat State welding LLC. I have been using an Everlast I mig 205, 60 amp plasma cutter and a 250 amp AC DC TIG machine from Everlast for The last 5 years the only failure I've had was a low voltage power supply in the MIG welder that tech support told me was a common problem because the fans fail and take out the power supply. I sent them information from my own troubleshooting and they sent me a new power supply that arrived within a couple of days. Everything came with instructions and worked out wonderfully. after 5 years of hard use I had to clean and adjust the points on the tig machine yesterday. That was a super simple job and now I have an HF arc start again. these two things are literally the only problem I've had from all three of these machines using them daily for The last 5 years. Once a year I open up all three machines and blow them out thoroughly. But that is the only maintenance I do to themI have been blown away by the quality and performance of the Everlast machines and we'll put them up against a Lincoln or Miller any day of the week. I love my Everlast equipment and would suggest taking a close look at it for anybody who's trying to find get equipment on a decent budget for their shop.

Awesome vid. Love my everlast 185!!

Weld mean weld green! I've heard alot of great things about everlast!

Weld mean weld green!!! Love me some Everlast!

Great information here!

Great video, hoping to build myself an exhaust system over the winter - thanks for the info dude

I've had pretty good luck with *Solar Flux* type B for stainless exhaust tubing. You dissolve a small amount of the powder in methanol and paint it on the back side in lieu of Argon backup right before welding (it can fall off when dry). Only mix what you need. The residue is glassy and really hard to remove, so this is not a great choice for hygienic work like food plumbing or intake runners, but it's the cat's meow for exhaust work where a bit of debris is OK. I think it saves a lot of hassle and some money. Besides, it was a classified technology in WW-II.

Nice work, explains a lot ,thanks man

very nice vid, explaining and showing why.

Weld mean weld green! Love it

i had no idea that everlast had there own RU-vid channel awesome tons of great videos

Weld mean weld green. I'm almost done with welding school. This would help out soooo much

That’s the first time I ever seen anyone use aluminum foil to purge, not hating or anything, just first time ever seeing it be done like that, I learned using tape, one side completely closed for the hose, and the other side little pin holes so it flows out, and keep tape where the welds are going to be done. Great job!

Wow, finally a Everlast video! I really enjoy my water cooled 210EXT ! How about some vids on 18ga or 16ga lap and fillet welds - Aluminum ; with and without pulse And the settings you use (d). Tacking 18ga Aluminum would be helpful also. Thanks for the Video Chris.

Just watched weld tubes video on the giveaway. Those guys are get definitely awesome your guys unit look awesome. I'm a new welder maybe 12 hours in. but seen a recent video video of purging the inside of the tube with gas. Finnagins garage. If you don't load the tube with gas on an engines exhaust or turbo set up it will pull the crystals that form on the back of the welds and could ruin a turbo. Great video showing both with and with out gas.

Fairly short and to the point. Good comparison.

Thanks so much for your video

EVERLAST 🍀

It would be advantageous to move the tin foil plugs in closer to the area being welded so as to reduce purge time and make a more perfect inert atmosphere inside the pipe.

great information

Weld mean, weld green! Trying to get a start on my welding career and fix some body work on my truck.

Awesome video so informative

“Weld mean weld green” been needing a welder would love it to be free lol

Weld mean, weld green. 🔥

Weld mean, weld green Really need this to start my career off on the right foot

Weld mean weld green! 🤘

Weld mean, weld green. 🤘🏼🤘🏼🤘🏼

Subscribed!

Good job sharing

Great example and explanation!

Weld mean, weld green Perfect for the shop

This reminds me of silver soldering in HVAC&R. Purging nitrogen inside the copper pipe at the proper rate so you don't blow out your silver solder and making pin holes. The purge in silver soldering removes the oxidation of the braze and the copper and doesn't allow carbon build-up. Basically the same thing I believe, only now we're welding. the next step above silver soldering, and we want a strong weld so this adds to the process. YAY - Argon!!!

Man I would love an Everlast welder

Hey brotha love the videos! Just curious (Now this maybe an overtly dumb question since I'm basically a layman in terms of welding knowledge) but I'm a very diy guy whose instinct is to always get something done on the spot without buying the proper and necessary tools for the job so my question is, what if I don't have an extra argon tank laying around? Is there any other easily obtainable gas' that I can use as a replacement?

The Myth the Man the Legend, awesome Chris.

For other people on SI units: a CFH is cubic feet per hour. 1 CFH is approximately 470 cc/min.

Clearly worth it.

The legend

“Weld mean weld green” would love a dedicated tig machine!

Nice. Thanks 👍👍

If you want the purge to come out better you need to diffuse it somehow. The way that a lot of us achieve this in the field is by folding a piece of masking tape about four times and then taping over the purge hose end to act as a splitter for the argon to hit.

Weld mean, weld green! 👍🏻

"Weld mean weld green" I have one of your plasma cutters. Would like to see a vid about nozzle types and sizes.

Muito bom o vídeo

Weld mean weld green 🤘🏻

Would love to learn this skills

weld mean weld green... Good vid!

Extremely happy I watched this. Thank you. So, picture this. Building a curve with multiple angles. So if building a curve and everything is butting up lovely. Once tacked up. Will it be just as good with the purge? You had two open ends and you had one joint. I'm talking two open ends and let's say 6 or 7 joints. Is this the same set up?

I saw the title and thumbnail and said out loud: "oh hell yeah"

I'm gonna learn on a budget mild & aluminized steel build, will have thick stainless collector flanges... what filler and what else changes?

I know it’s all argon, but can flow from the purge blowing through the seam disrupt the gas coverage from your cup? Do you need to use a higher CFH through your cup when you’re welding pipe with a purge than you would typically use with the same size cup welding plate?

It's only exhaust tube so does it really matter? I get your point though for other projects

OK, so TIG-welding stainless tubes requires this procedure with gas on the inside?

What wall thickness is recommended for exhaust and turbo manifold?

Weld mean weld green. 👍👍👍👍

weld mean weld green ✊🏽

What shielding gas would be best for welding sch 10 304 ss to mild steel? Plan on making turbo manifold for my cruze since the factory one's nothing but issue's & expensive to replace for something so small! TIA

I like your videos , not many do ss steel thin

is it going to crack or leak without the argon gas? or is it an ok but not perfect job?

can you use single argon bottle with a dual flow valve? one too the welder the other to purge. thanks

Should the purge cfh be equal to the torch cfh?

This machine is a beast #weldmeanweldgreen it's the only machine that gets in between

Do we have to purge when welding slip joints?

Why do we ensure the opposite side of the weld is shielded for pipe (this video), but not for other welds?

Weld Mean Weld Green ... Looking to replace an antique Miller Syncrowave 300 and a VERY Old Tri Arc 180 MIG

How come you add filler rod? I’ve always done stainless tubing with straight purge no filler autogenous sanitary tubing mainly

Sir itu hose masuk dalam pipe. Itu argon bukan ? So itu macane las tig tidak ada argon kah ?🤝🇮🇩my from indonesia

what is the thickness of the exhaust tubing? And what volts/amps did you use? thx

Love to see 316 marine rail tubing. 7/8”, 1”

Have you guys tried using solarflux B before?

Love it !

Forget about Happy ever after this “weld mean weld green” machine is the “happy everlaster” the only machine that gets in between!!

Amo soldar alumínio

It might night looks as nice but wouldn’t it be stronger wirhout the gas?

Stoked everlast is putting out some content. I bought a 200DX a few months ago.

Weld mean, weld green!!

Can I weld with Rahin but back purge with c25?

UK...watching as ever. So many don't understand prosperity UK here wanting to explain the basics of this..but being blocked guy's. Hopefully your understand everyone..

Weld mean weld green !

Hope I win the giveaway would love to have this welder

Weld mean, weld green!
