[@jed3219]

As a welder fabricator, I'd love to see a follow up on how the exhaust holds up over time, instead of back purging too you can use solar flux next time for when you don't want to use the extra argon, the welds become more brittle when you don't back purge too it's not just about the aesthetic and its tendency for rusting quicker, it's worth doing at least a backing plate or something, love what you guys are doing! Killing it for how fresh you guys are, keep at it :)

[@GoPaintman]

Should’ve mentioned that cleaning your parts with brake parts cleaner can be extremely dangerous. If your brake cleaner contains tetrachloroethylene, you can expose yourself to an extremely poisonous gas when welding. A lot of the “50 state” brake parts cleaner no longer contains this chemical, they use acetone instead. But always check, and it’s honestly safer to use acetone by itself.

[@rodanone4895]

one hundred and ten percent!!! acetone. and be careful with the acetone. some have oils and grease remnants emulsified when you buy it. apparently there is reagent grade acetone where this ingredient is controlled. but i can't find it. i start with acetone. then scrub again with a dry cloth. the danger them becomes lint... shop vac. then weld. tom eager from MIT has an amazing series on KZbin for welding metallurgy, fusion welding etc .. but, the algorithm is unlikely to recommend it. he talks often of welding cleanliness even with low carbon steel.

[@constantproject1450]

I was literally just about to say the same thing when I saw him using brake cleaner. No bueno

[@FleetTech97]

It creates mustard gas right? I know when I was working in the mines I got told about a welder who cleaned up a bunch of oil with brake clean then welded in the area and ended up dying because of it

[@rodanone4895]

@@FleetTech97 phosgene i believe can be created. but chlorine gas by itself also happens and will cause immediate acid products straight on the lung walls. mustard gas has sulfer, where the yellow comes from, and sulfer occurs in steel so it is probably also a byproduct. keep chlorine away for so so many reasons. it corrodes stainless.... as you say: no bueno. word.

Agreed as a tig welder myself, aluminum so it’s a lot different, but I’d say more gas and weld kinda in segments like a inch worms body, you’ll get good dimes like that even without back purge 👍🏼

[@nickthelebo]

@@CandidKiller but the insides of the pipe will crystallise and will not have proper fusion with out purge on stainless and with heat and vibration the join is the weak point so it normally cracks (edit .. when welding stainless I'm talking aluminium there is no need to purge )

[@fatpad00]

@@nickthelebo What is the actual purpose of the argon? I assume, because it is inert, that it basically blows away atmospheric gasses that would react with the molten fresh weld? Is that what the crystallization you mentioned is?

[@CandidKiller]

@@nickthelebo Did not know about the necessary back purge for stainless, glad you informed me. I’ve only been professionally welding for almost 3 years and started with mig then went to tig and do aluminum now at work and we do a little mild steel so nothing we do requires back purge

[@CandidKiller]

@@fatpad00 Argon in short is what you use to weld, it’s a gas, and it allows for the weld to lay cleanly, without argon it’s a bubbly mess and you’ll never get a weld down, we use 75% argon and 25% helium for aluminum at work but all metals can use 100% argon, don’t quote me, but like steel can’t have the helium, they make another mixture for that.

First off, if that was your first time welding…amazing job! Second, check out stainless autogenous pulse tig, it has totally changed how I weld stainless exhaust. I understand this is a beater but it was my understanding that you shouldn’t stiff weld the exhaust to the chassis as the vibrations will cause some points of it to crack (hopefully not near the headers. The hanger needs bushings. Also, what a lovely head of hair.

[@crisnmaryfam7344]

The filler is helpful for extra strength I would think, autogenous welds are nice because you use only the material you're welding, but it can leave the material a bit weaker than a good filler bead with back purging. This is just my experience though so if I'm incorrect I apologize lol

[@paytonlee2896]

Very underrated comment. To a newer welder, they may not notice. But if you do the different grinds back to back, you can really see the difference. It’s why you want a large angle (60* point) for thin metal, vs a shallow angle (15* point) for thicker metals. The large angle allows you to have a more focused arc, where the heat affected zone isn’t trying to melt a larger area of the metal.

WHAT EXPECTATIONS ? I HAVE NONE ANY MORE.

[@ivanstepanovic1327]

I remember that back in the day, my exhaust on my old VW got rusted. So my friends recommended me a guy that does everything on his own... Decided to give it a go... And really, literally, the guy did it from 0 right before my eyes! He just had a bunch of steel pipes he was bending according to measures! As for mufflers (I believe that is how you call them), he just had a bunch of flat tin sheet. And he did the same; measured them up, cut them, bent them and welded as well as putting some isolator material or whatever inside! Then put it all together, welded it and installed... And it worked just fine! That was 6-7 years ago in a 1991 VW Polo! 2-3 years ago I sold the car. The dude who bought it is still driving it with the same exhaust! My current car is a 2004 Citroen C2 and it has chrome lined exhaust in very good condition, so I hope it will last a bit longer...

i love my damn car. idk why. ive had it for 10 years, on its 2nd motor, and still sitting on jack stands since 2020. you guys motivated me to get my exhaust system together this weekend. i have all the tubing and what not, just lazy. thank you donut

[@sanchitachatterjee1402]

[@activemanishere]

Some advice for the future. Take the entire length of tubing, measure to the first bend, cut your 4°, weld it back together, measure to the next spot and repeat. Then at each bend, you only Weld one seam rather then 3.

[@CJONE764]

Thank fudge someone actually said this! This is how we do it at work. It's proabably 70% faster, your putting less heat heat into the material, your not making multiple cuts so there's less room for error. Also why have it on foot pedal why not just have an auto push button start on the torch? You're reducing variables which makes the job cleaner again.

[@deathanddismembermen]

Good job getting used to the TIG. Learning how far you can choke up on it and the distance for you arc was the best part for me. And when you get a good rainbow pattern and it looks like you have laid down a row dimes you can’t help but smile.

[@NevaSmoove]

Tell the soundengineer this episode was a masterpiece!

[@thelethalmoo]

god damnit i've got that 'give it the beans' song stuck in my head for the day again

[@sleazymeezy]

Get ready for Suck. Squeeze. Bang. Blow

[@chrisroemer1129]

Am in the middle of making my own custom dual exhaust on my Audi B5. Seeing this video goes to show how badly I need an angle finder, lol. I had to cut the straight pipe that a previous owner had slapped on, and replaced both cats with a pair of amazon units, got 2 sections of straight pipe, a portaband, and I've had a flux core welder for 2 years almost. It's coming along pretty well, I think. I didn't believe that butt welding would be as tricky as it is, but I've made do. The .035" wire seems to fill the oddball gaps, and it's all very solid. I'd like to do a TIG welded exhaust with all the back purging, but I don't have that kind of money right now. I'm making this exhaust for roughly $225. It's been a pleasant experience, and I find I enjoy doing all the prep work that goes into it. It's all been quite therapeutic and peaceful, minus dropping bits of dirt and road grime in my eyes while under the car, lol. Thanks again for the informative watch, your bimmer sounds sweet asf

[@WarriorsPhoto]

I admire your desire to learn Zack. That is admirable and it makes this show fun to watch. See you in the next episode.

[@Mr3truman]

This is an awesome series and a great video, keep up the good work Donut!

[@SuperWaterskiboy]

hey Jobe! i work in new product development for Miller. Awesome to see yall have Miller in the shop! as far as your curiosity goes.. I did a lot of drumming when i was younger and can say that i am naturally better at tig than any other form of welding.

[@killroy2993]

Stainless tech tip...tac it, continue this way. Then make a controlled leak of argon inside the pipe... Stainless makes crystals. Then can break. So sealing one end with argon supply to then making a very small leak on the otherside will did the pipe, stop crystals. And maybe save your turbo if your fabbing the induction.... Behind the downpipe it's not as critical, but it's good practice

[@ernestocastellanos6446]

He already mentioned purging the inside. What he didnt mention is getting a gas lens lol

[@JaredConnell]

18:55 So I guess the real gains were the friends we made along the way.

[@northernkushreviews7335]

I love that you guys do a great job with the closed captioning because when I'm too high I need to read them!

[@samguy7587]

I'm a drummer, I picked up tig welding faster than my classmates that had the same experience as me because of my coordination. However, tig welding is a much different movement. patterns however, like a verticle v pattern I picked up really fast due to my inherent rhythmic ability

[@KeRowKi]

Love this show, thanks for the content... shout out to your editor for being awesome!

[@theinfofoxgotgears3782]

Not gona lie I looked up on Google to how to make rally car but no one has done one but now I found out u guys bin doing those so now u are first people on internet to show veido how to make rally car custom

[@sketchycloudgaming3581]

seriously the stuff these guys do is exactly the stuff i would love to do eveyday any application?🤔😂

[@B.Colby107]

I have to say I absolutely love the Warhol inspired shirt

[@michaellemmon7748]

where can we get it

[@MarioPescaru]

Zack the type pf guy who says he did it bad but still very impressive

[@cinnamonrollypoly]

"I'm just gonna plow, er, peddle into it." Yeah, I caught that.

[@rosskuemmel6434]

It’s next Wednesday, Jobe. Where’s my new money pit episode??!

[@anattempttomakecontent776]

Ikrrrrr

[@ImDying2Live]

Came back here to see if other were complaining.

[@chrisbear562chris9]

Zach is my favorite Donut guy, I could watch him for hours. LOL I think I already have with all the videos

[@garrettweaver9450]

Oh man missed Zach and Money Pit! So happy to watch this, this is one of the coolest videos. Zach going full ECS on that exhaust sounds soooo good though!

[@jacobjanssen2959]

this made me miss welding, dam it looks fun!

[@robertlane367]

...so for "new" tig welders...u can lay a bead with some filler rod. Hit it with a wire brush after it cools. Then "wash" it by going over it again with the tig torch. Make sure if ur doing stainless steel to use a stainless brush...if not it will embed mild steel and leave rust spots

[@jimtravels]

"...kinda late, we got neighbours, so we're going to leave it to tomorrow" How can I give more thumbs up haha

[@DilRyeMaster]

101.9 from stock exhaust? I thought CA was supposed to have a 95 dBA limit? 😆

[@TheQuilava96]

Shhhhh 🤫

[@grey5626]

@Superluminal: You are correct! "The sale and installation of an aftermarket exhaust system remains legal in California so long as it does not exceed a sound level of 95-decibels when tested under SAE J1492 and complies with all other exhaust and safety laws and regulations." In other words, the stock exhaust was already illegal and this aftermarket mod is unequivocally law breaking territory.

[@vladivosdog]

Shhhhh 🤫

[@Doctor_MX]

Tip for tig welding stainless, you dont need it, but using a gas lense will shorten your tip and cover your metal better with gas, makes working with pipe alot easier

[@gradientO]

Honestly, it sounds like the car now farts loudly 😂
