My son is a union ironworker and certified welder. I taught him to solder when he was about 8 years old, stick welding at 10 and by 12 he was TiG welding. I know how to weld and am lucky enough to buy good welding equipment but I’m no way in the same league as him. His welds are a thing of beauty. They actually asked if he wanted to teach at the union training center when he finished his apprenticeship. He was 22! He told the lead instructor he’d think about it in a few years after he got real world experience under his belt. I’m so proud of my son!

[@kjm0677]

Fr, the story about his brother being on fire and saying I'm amost done had me dying.

[@alexisrivera200xable]

@@kjm0677 The thing is that while funny it's really common, you are welding and smell something burning which is kinda normal in a shop then look down its your apron or the shirt that is on fire, you put it out and keep welding unless its a big fire. Sure you freak out the first couple of times but welders on the job have set themselves on fire enough times to just know how long they have until its too much fire. (Just don't tell OSHA!) Experience can bring some complacency with it.

[@Yvolve]

His delivery is s spot on for everything. The "O, I get it, I get it, that's what sucks" on the first clip is gold. The look he gives the camera as well. The man could be a stand up comedian with a routine solely based on his experiences working on cars.

[@Hydraulic67]

My Grandpa was a welder for nearly 70 years. When he was helping teach me to weld (when I was 8) I told him that he was a really good welder, he looked at me and said “you can’t be called a GOOD welder until you’ve welded a train car full of wire”. Guess I’m just fair after 48 years, but I can live with that, it came from Grandpa. 😁

[@WhatIsSanity]

Hah! Every person I knew that welded didn't have a high estimation of their skills either. Even my father was humbled by another mans skills and that is unusual for him. Those welds were really good though, so understandable why he still at 15 years after retiring hahaha. No seriously I worked on some of the steel he welded and it was factory grade or better, which was especially impressive given the dude was so old he shook like a leaf in the wind and nearly expired after a couple of hours. Some of those joints were so clean it looked like they were bent or cast as a single piece. First time I met a master of their trade. The old man was very nice too.

[@anthonyellison8680]

I wish I was smart enough to to have asked my grandpa how to weld

[@Stop_Gooning]

Never said how big the train had to be! Lmao I have about 1,000 hours under the hood and I'd say I'm "alright"

[@poolhalljunkie9]

Nah. You want to be a good welder then weld all the train cars together and let em ride. If they stay together then you're good. 😂

"Kids, learn to inspect welds.".....wise words from our man Sandro 🤣🤣👍

[@superdoodle2]

I am a weld inspector, pipeline among other things as Sandro mentioned. The red stuff you see coming out of the weld at 10:00 is called dye penetrant, it is a specific type of oil colored with dye that draws itself into cracks and other imperfections. The surface is then cleaned and what the guy in the video is spraying is the developer, essentially aerosolised chalk, that draws the red coloring out to the surface. Also where I live, carnival rides are definitely subject to regular weld inspections, at least on load bearing areas and repairs.

[@Stop_Gooning]

When I get another 1,000 hours under the hood I want to get certified as an inspector.

I love how Sandro is their expert on everything car related.

[@CRneu]

it's cuz he does custom work. Once you get into working on old cars you need to know how to do custom metal fab. In general older cars require a lot of custom work, so you just learn to do it.

[@neruneri]

@@CRneu it's pretty clear from how he talks about it that he likes hanging out with the subcultures within the broader car community too, so he probably really has seen just about everything.

[@cespa4206]

Would love to see a season of HiLo with Sandro and Angelina but instead of a hi car and a lo car they each just have a budget to play with each episode allowing them to cheap on certain things so they can have a higher budget for a different item next episode etc. Would be interesting to see where they decide to spend up or cheap out for certain parts which can be compared overall

[@MephieStopheles]

Yes. This.

[@tommychew6544]

I watched an industrial welder do some stainless steel piping connections once and what made me stop to see the outcome was that he was making some weird looking upper body and shoulder movements with a Tig welder. It was the most perfect smooth weld I have ever seen! The flow of the weld looked like a machine had done it.

[@ponythroat1405]

a machine did do it. a tig welder is a machine.

[@Hydraulic67]

I’ve been welding for 48 years, one of the first things I learned was just because it’s aesthetic doesn’t mean it’s a good weld. The pretty part comes with experience, make sure you have your prep and penetration down first, then practice on making it better looking. Lesson 2: just because someone bought a large tool box with tools doesn’t make them a mechanic, same goes with a welder.

[@reaganharder1480]

Yep. You can make an ugly weld that penetrates and you can make a pretty weld that don't. That said, quite a few of the bad welds shown in this video pretty obviously didn't penetrate..

[@HrLBolle]

The Trades take time to grow and deepen the learned. As seen by "rechtschaffend frei/fremde Wandergesellen" on their "Walz" over here in Germany and actually throughout the entire Euro - Asian Continent if one so desires. most often they are Carpentry Journeypersons in their Journeymen years

[@randompizza220]

I learned how to MIG weld when I was on a Baja SAE team. (We had opportunities to learn TIG welding, but not enough access to a machine to get enough practice in outside of the few group classes.) At my university, we learned from people who were trained to be aircraft mechanics and they made sure your welds were ON POINT. Plus, our competition made us do weld samples for every welder who welded on the chassis, with destructive testing for one of the sample types. I found welding to be pretty fun and relaxing at times. The whole experience definitely made me start to look around a lot more at things that are welded together and at the quality of the welds.

[@dakotadennett6979]

Sandro gunning for Nolan’s job, and I support that decision 😂, but for real we love you Nolan! Bring Sandro to the donut team and just give him a shop that does real mechanics stuff let him do him but get real day to day info

[@Lady_Elva]

Sandro reminds me of my dad with how he works on cars and welds too. Though my dad was an Iron worker first and a master mechanic second. He had to wear full leathers when welding and years ago he was welding in an enclosed space for a building on a construction site and he felt this pressure and sudden heat for a moment (note: he had earplugs in so he couldn't hear anything). He was confused for a moment, finished up his weld and when he came out he found out gas had exploded down where he was. So please, for the love of all that is holy, wear the damn leathers! It WILL save your life!

[@nephicus339]

Flux core is my favorite; it's like mixing MIG and stick welding. And then a bit of TIG just to clean up the surface (if we're not grinding). I do alright; but I need way way way more practice before I'd put my welds out there. xD 11:00 - My welding instructor told me he inspects welds as much as he can see before he ever gets on a ride.

Our local carnival consists mostly of vintage rides. Very sketch welds. The last time I was there is the last time I ever go to a county fair. I was riding a spinning ride that moved you up and down in the air. One of the service doors flew open and proceeded to smack the rides being banged around so hard it was throwing sparks when it collided with the bars. The very lazy "I don't get paid enough to work here" worked, very slowly came over to the controls and decelerated the ride, rather then hitting the emergency stop button. Meanwhile the rides kept hitting the door. The door was a mangled mess (could have injured someone) and the ride operator proceeded to grab duck tape and tape the door shut. Everyone in line and on the ride noped out of there. Welds on the rides were bad but not only that, very cracked and rusted supports.

[@aaront4494]

Thank you for this. I’ve done stick, mig, tig , resistance, compression and electron beam welding. On pretty much all types of steal and aluminum. And special alloys for the different military projects. I love doing it.
