$80 for a GT3 fix. I'd call that a massive win for the owner.

I'm in the Industrial Maintenance and Service and I understand completely what you mean, 2 weeks ago I had to deal with an axle that broke on the headroll of a conveyer. The axle was welded in a cage and it was broken just outside the cage due to a piece of metal that was hanging around, everybody there at the plant told me it could not be welded but they had no spare either. So I said I think I can do this besides waiting two months for a new one wasn't an option either. I stick the whole damn thing in a big lathe drilled and tapped a hole to fit a 8.8 bolt and made a bevel of around 60 degrees, did also the other side, cut a bolt's head off and screwed the two pieces together to align them then I tigged my way through and let it cool down from time to time. Filed the whole thing up and turned it flat with the lathe. Since then it is still working and a new one is ordered , so I hope it will survive that long...sometimes you got to do what you can, nothing less, nothing more.

The "I charged 80 bucks to fix that" was funny as hell

It appears your big waiver worked, no haters commenting. At that point in your life when you have to get new haters, the old ones are starting to like you.

I happen to be a youtube certified (watched a lot of videos about welding) expert welder and I call this a valid repair under the circumstances provided. Let the haters swallow hotdogs sideways.

Fit, Form, and Function. What you did is what I would have done too. That is also what engineering is supposed to be about. Sometimes my fellow engineers forget that.

Positive Attitude , Don't worry about what other people think , you are a Trades Man and so am I , you did it the right way for this application , be happy I am , love your work Mate , all the best from Australia

Thanks for your channel my guy. I’ve been watching for years and finally got my setup going. Thanks for sharing your knowledge and helping us new folk learn a thing or two.

Great repair! It might not be a perfect new piece but its functional and most importantly its what the customer wanted!

Hehe, watching this tells me that my purge method worked when I welded Ti that one time... I just used a rubbermaid container and purged it with Argon for a while before lowering the torch into the container and fusion welding the joints. No color and no TiO2.

My old team leader used to say it best. "For what it is, it'll do"

The way you said you charged $80 for that was hilarious. Like it wasn’t even worth the headache or lowering of your fine standards. Love your work and that you are a fellow local

Sometimes gotta give the customer what they asked for. nice to see and quick video from you.

Decades ago I was down in Texas & watched a seasoned welder do the same thing. I asked him what kind of weld he called it, he said "Weld'n mud-puddles". Difference tween you-n-him, your superb quality. You dance those 'Mud Puddles' like a tap dance artist.😎👍

I'm halfway through the video and I'm so happy that I'm not alone in the practice of saying "basically, it's fubar, and it won't be correct.," I've had too many people try to deny my knowledge that it almost made me sell my shit.

Love how often you see "you didn't do this properly!" From folks who have only read about the proper methods in a book or watched a video and ignore the fact that an exhaust to is pretty much the lowest stakes part imaginable.

You really need to smack it a bit harder and say "that's not going anywhere" to make it last longer. Other then that ir seems totally legit.

So, you only charged the argon you used, that's a win for the customer in a crappy part. And I don't see any space engineers on the comments, that's a win for you. And another win for you is this comment. As fast Matt says "all hail the algorithm"

Well done! And yea I caught the “Coool wwwwwhhhhiiip” reference from Family Guy. Well played too! And forget the aero space perfection gurus. Not all repairs need to be museum quality. You took what was a very expensive ruined part and made it function again. Bravo.

Nice to see that my Prime Weld will weld titanium, even incorrectly. Bought that welder based on your review, thank you.

I have TIG welded for over 5 years with no schooling. I just taught myself. I also don't have any shielding so this is what my welds look like and when I use too much heat. If you don't have shielding using a aluminum bar will hope so much. It stops it from bleeding through on the other side.

As a customer, all I would want is it to work! Keep it simple 💪💪

> aerospace professionals I.e. engineers who have never fixed a thing in their lives

Titanium Dioxide is also found in ranch dressing to make it bright white.

Great job 👌🏻👌🏻 Apart from starting from scratch, and costing a fortune. Definitely the best approach 👍🏻

As an aerospace professional.....nah just kidding. I'm just commenting for the algorithm. Nice work.

Great job sometimes things are broken and you just fix them as best as you can

I love your common sense approach to fixes. That's one of the reasons I watch your channel. And your distinctive voice. Two thumbs up.

Thanks for another video. Your honest in what you do and explain things very well

I’m mad already and have t even see the video yet

I really enjoy the live commentary along side the voice over.

I am an Aerospace professional and certified aircraft welder. I would have done the same repair. It's about function. That thing has no structural requirements. Those that complain can't do better cause they don't have the knowledge.

If you can please some of the people all of the time and all of the people some of the time you'll be ok. Great video.

Haha, the "german intro" confused me (as a German) more than it should. For a short time I was wondering about clicking the wrong video instead of the TFS video I wanted to click. I really had to smile, when I got it. 🙈 By the way: great repair job, it's about helping the costumer and not about doing it the 1000% right industrial NASA way.

Your vroom vroom bit.. funny. I always say when I fix something “it’s not a fkin rocket ship dude it’ll be fine”

Nothing to say, just commenting for the algorithm, Keep it up man, i love watching your vids about literally anything.

Military aircraft are known to have this problem especially in their engines and engine compartments. I'll also say that you might be able to have a solution by baking the entire part in a zero oxygen environment and keeping it there while you use a titanium welding techniques to help the bonding. I'm also going to tell you that it's fairly likely that you don't have the proper heating oven and even then it probably won't be much if any better.

I was a little confused at the German in the beginning not that bad actually Greetings from a fabricator from Germany

These are just the exhaust tips, right? All they have to do is look like they are important. JB Weld and send it. As an "aerospace professional," Titanium Dioxide is no joke. Every mission-critical Titanium part in an aircraft has a pedigree, inspection interval, and a service life.

Thanks for the reality check

so I'm a noob and trying to learn this stuff. I can definitely see similarities between the back side penetration of this titanium and some stainless pieces that I've been practicing on. I've been thinking about how stainless gets all nasty and oxidized if it's not back purged of shielded. I have welded some stainless exhaust tubing with solaflux on the inside with pretty decent results. Maybe this Ti weld would have been better if the original welder used some solaflux on the outside? Anyway, one thing I haven't ever seen any videos addressing is shielding of thin, flat stainless plate/sheet when TIG'd together. I have butt and lap welded on some 18ga and some .030" sheet. Strong penetration on the thin stuff is imminent and will crystalize unless I put some solaflux on it. I see loads of yt videos of people welding stainless, and if it's a tube or pipe, shielding the backside is always addressed, either by back purging or solaflux. However, when it's a video of welding flat stainless, the issue of the back is completely ignored. How are you more experienced welders treating the back of sheet stainless? tia

This is a perfect demonstration of why you pay for the job. You are not buying the welding, any fool can do that, as the first job amply demonstrates; the money you pay buys the knowledge, skills and abilities of the tradesman to provide you honest appraisal of the job and completion in accordance with the appraisal.

Beter to have a true Fabricator repair that part than some so-called "aerospace professional."

titanium dioxide is also in candy, food, and soaps in the US. There is a push to ban it in those items like other countries have done

will hold untill the next time it doesnt hold. basically the life of weld repairs

Come on Porsche. Such shoddy work.

I’d be super happy with that entire transaction! Not only did he get his part fixed, he got a video of it being done, all for $80! I’m right this moment trying to figure out if there are any unitized welding tasks for my project car that I can send your way. Nice work!

Always keep inswool around. Stuff the tubing full up to your weld joint to create a wall to contain more of the gas.

you did that all wrong... it'll never fly! 😂🤣😂🤣 whhipp! thanks for the video. this was super helpful.

Some coarse brown Scotchbrite pad on a random orbital sander (cut into the appropriate circular shape) and sprayed with regular PB Blaster will get that welding table top looking like new.

Unless I misunderstood the problem, you could just chemically etch the titanium dioxide layer away using a combination of hydrofluoric acid and hydrogen peroxide. This won't harm the underlying titanium but will completely dissolve the oxide layer. I could not fully understand though, maybe he believes there is a bunch of oxide mixed into the base material itself? Even if that was the case, couldn't striking an initial arc after the surface layer was treated bring all the oxide to the surface? Just speculating, as this could have been an easy solution to the problem.

That's good for your business, the guy will probably be back every 6 months or so until you say it's too cooked and need to be replaced 😂

dude you made my day (tryin‘) speaking german 😂😂😂👌🏼

great camera work and very informative cheers

well, to be honest, this is exactly what i would expect from you,...i have seen you how you load trailers..... O:) ;) seriously tho, this is a wonderful insight and information that technically may be "incorrect", "wrong", or otherwise, when it comes to "proper technique", and those that would attempt to point this sort of "incorrect information" simply are ignoring that this most likely would not have happened if the manufacturer had actually done it "correctly" in the first place, no?? so good for you for sharing, and explaining the process and reasoning behind your repair. i am certain the customer was quite pleased with the results. and krud kutter it the best!!

lol the amount of aerospace engineers that told me 0.0005" was out of spec i just laugh when they couldnt even figure out that the material was 0.007" out of spec in thickness before i even got the part at the job. im sorry but i have not heard of issue that was caused by half a thousanths of a inch when it came to a "cover plate" for a power supply box become "unsable".

Thanks

wonderful Justin....

question: does the oxidation go all the way through the metal? I'm not familiar with titanium. Could you brush the oxidation off somehow and then weld the other side of the weld? I get that this is basically a cosmetic piece and the single side is probably strong enough, but I'm curious.

Im no pro, priceless knowledge in this video, thank for making it man!

i'm only here for the "aerospace professionals" 😆

I have followed this channel and this man for a long time. Very much useful information and he is very smart. But I've never seen him use a respirator. Not with aluminum, not when he's welding stainless. How can this be?

love your vids mate keep up the good work

This is the welding equivalent of WhistlinDiesel, LOL.

Nice and practical 👍👍

As a non proffessional I would of thrown that in the scrap pile and built a thicker material one. It's bound to crack and break again with the high vibrations. That's like those flimsy heat shields that crack and with the heat and vibrations then start rattling at the worst possible time like lunchtime at the drive thru.

Makes perfect sense. When you're welding a capsule on a spacecraft that supports human life, you can demand 0% oxidised titanium. When you're repairing a crack on a cosmetic exhaust tip, quality requirements aren't as strict.

Al Gore's rhythm has got me movin

I don't understand how having some contamination justifies inducing more contaminants. I do understand how that part is purely aesthetic and can keep cracking to kingdom come though.

im here to learn not bitch about how you did something. thank you for sharing your Knowledge and expertise.

80 box for may be 4000 box part. The client most be very happy

The oxide can be dissolved off the surface using a relatively safe product called Multi-etch - Or Nitric+Hydrofluoric acid, which is great but wants to eat your bones. It's really only long exposure to high temperature that the oxygen gets deep into the metal and messes it up. (semi educated opinion)

The engineer that designed this part and most other parts today needs kicked in the nuts. They don't have the sense to build most stuff right the first time. Building it right usually means with $0.05 more material cost in the design to build a better part for the consumer vs a less expensive part for the manufacturer.

Just found your channel and I'm currently bingeing on your videos, and I would've done the exact same thing.

And it bolts on!!! I guess maybe the German workers did not have z torque @ z proper specification on z fasteners. They will be cleaning toilets for a very long time, or they are eliminated from the production line..... Anyway just found your channel and love your sense of humor. Subscribed. God bless and have a great day!!!

how I help it to do some shielding without making a huge deal of it, we have another regulator and a small hose, on the end a metal tube slightly squisshed . And while I am welding another person, follows me with this hose slightly after my point where I weld. It cools the material down and works great on those shity pieces you can make a purge. I know you said the material was compromised but it can be better , this way you get no more oxiditation or even the old one gets better...

Seems like they could have made a pretty cheap purge rig when it was first made, and it would probably never broke in the first place, and looked way better. Nice going Germany!

Even the coloring would compromise welded titanium as micro fractures might start do develop in the oxidation.

Wondering, is the titanium totally destroyed or destroyed in that area close to the original welds only? (If the customer wanted) could you have cut them off and just shortened the tips a bit then shielded and re-welded? (Wouldn’t fix the base of the part though which may be why this wasn’t an option?)

I think you should retitle this to either I pick this up and I put it down. A lot! Or, I charged 80 bucks to fix that. Btw you did that entirely correctly. You do what you have to. Sometimes that means as little as possible.

😎👍 The algorithm says that was totally something. That's a exhaust tip. Cosmetic. As long as it doesn't fall off, it's good. Still, it's algorithmic something 🤨

"This part goes on the road, it goes vroom vroom - not pshew pshew"

$ 80 bucks such a deal, no judgement here....

Wait, you don't have a magic wand?! 😁✌️

cant please all of the people all of the time ,,, go for it.

It looks like it could have been welded in a sand blast incubator filled with argon.

Good deal

Giveing the customer what they want.

I would off done the same thing, there's not much you can do but start from scratch, good job mate

I think you did great. Just a question out of curiosity: what about cutting away a quarter of an inch (the damaged section) from the pipes and weld them back to the plate? A little bit shorter doesn't seem to affect the proper functioning of the part 🤷‍♂️

Hard to shield, that crap. Especially considering the damage already done. Would have solar flux worked?

If it works 👍

I was thinking that you were going to do the other side also?

My buddy keeps paying crap-tons of money for European cars because they are "better quality". Imagine paying $224,000+ for a car where they couldn't even weld the exhaust tip correctly...

"Hwhite? Cool hwhip?" Thanks for the Family Guy reference 😀 Anyway, thanks for the insight again and what you did makes absolute sense. Can't F it more if it's already F-ed. 😀

Uhm.. So I understood the German? I mean, not word for word but I knew what you were saying. Context is incredibly powerful lol

What about setting up an old sand blasting cabinet into a argon cabinet for welding in a inert atmosphere

The only people that are going to get technical about how it's being fixed are people who just want to "one up" you.. in the real world this is exactly how it would be fixed...🤘

Keep up the great work bud
