Have you got a Quick Tech idea? Lets hear them!
How to make a good Lemon Squash...
When or why or how to port, port-match, etc.
Different Gasket materials and where they come into play🙏😁
The Skid Factory I would love to see a build being planned / roughed out. I know you go through it when you film but would love to see the convo with the customer on where it’s going to go 😎👍
"Wastegate" external; internal; boost range; setup; maximum of each other
"If you put your ear up to the end of it, you should be able to hear the tears from internet welding purists..."
Perfect is the enemy of the good. Unless you're an internet commenter. Then perfect is only "good enough"
These videos are perfect! There are a lot of CZcams channels out there that show the best in what they do, so a welding channel is going to show their best welding technique. You however show the best balance between cost efficiency and quality for the application. You are even doing differently with each car and the level of quality the costumer wants (to pay for!).
My dad owns a car shop in The Netherlands and this is what I find as one of the most misunderstood things of customers. Some want top notch quality but don’t want to pay for it. It just doesn’t work that way. Besides this, Al has proven to be an infinite source of automotive knowledge and experience. This is why I think you are one of the best or even THE best automotive channel on CZcams. Thank you for making these video’s and keep creating awesome stuff!
Yeah, Al provides so much information, and they all based on personal experience. So it is much different, to get info from someone with years and years of experience. Or the internet moron who only knows how to do these things from reading about it online.
Grinder and paint makes me the welder I 'aint

Makes for a skookum weld
poopenmayer ha ha a nod to ave 😂😂
The amount of people I’ve said that to since I first heard AvE say it 😂
Needs to be followed by a stack of dimes makes a fabricator I aint ;-)
Very impressive getting the tape of the roll with gloves on
My thoughts exactly ..... Tape Mastery like a boss ....
I struggle getting tape off a roll without any gloves on
i kept waiting for the moment he'd just pull them off like i know i would have. Nope!
I was legit impressed lol
I would love more of these "you don't need to do this because the internet says you have to" vids to exist on the intertubes. They are properly beneficial to the people like myself who may embark on such things, and hopefully put an end to the trash that I've seen while researching what I intend to do.
More debunking please Al and Woody. You guys are real.
This is why Al hit it on the head. I work as an ASME Section VIII/XI Welding Engineer for context. He isn't dealing with a construction code. I expect a visual inspection; but no PT, tensiles, bends, ferrite, impacts, corrosion, chemical requirements. Not dealing with dangerous/lethal service, or something that needs to be built in such a way to not blow somebody up. Best practice is to not have heavy oxidation/sugaring, but otherwise in this context have fun and make it happen.
As someone who works in the stainless steel tank building industry I must say that this is a very good explanation of purge wedding.
A more budget way to purge is to use nitrogen but it means that you need another type of bottle.
You can also use a copper backing bar if you have flat things to weld (obviously no good for tube)
We use anything handy for caping the end of tubes if you have a cold end you can use cardboard or plain tape.
Also it is very important to note that it is a waste of time and money to purge weld on a lot of applications.
I'm glad this quick-tech wasn't super snappy. You didn't just explain what's what, but filled in both wider context - where purge welding is really important, and likely where the overapplied ideas come from - and more narrow context - this kind of work, and why we rarely actually need it for this. Your "blurting out what's in your head", adds valuable and materially important context, and the personal touch that turn decent content, into unique, great content.
If people understand the _why,_ not just the _how,_ the lesson tend to stick a lot better, and people become / can work more independent(ly).
Thanks for blurting whatever is in ur head I appreciate it very much
This is what makes decent content, into unique, great content :)
I'm a fan of quick tech regardless of how long it actually is.
I like long quick tech haha, would listen to Al talk about whatever for hours.
Seems to me the topic should dictate the length. I’d listen to Al talk about cooking anyway.
If you French fry when you should pizza, your going to have a bad time!
The look of disappointment on your face when you knocked the angle off the clamp the second time was classic. LOL
Finally some common sense about welding. I have a friend who is a real pro welder that does mainly dairy work and he gets a laugh out of the internet experts. When I asked him he basically taught me the same thing.
A 23 minute quick tech on purge welding is exactly how long it takes to bitch slap the silly internet experts and convey what needs to be said to give everyone else a firm grasp of the basic concepts. Perfect. Keep blurting out useful things!
Al's pipe fabrication is top notch. I shuddered thinking back about all the gaps I've welded up with MIG, TIG and Arc welders over the years, lol.
How good is Al? That bloke can find the start of a roll of tape with leather gloves on!
Impossible thanos meme
Very good explanation. I think many "people of the internet" forgett that somebody is paying to have you do the work. If you add cost not needed or not wanted by the customer. Well your not gonna have a job. Great work fellas! Great vid!
Yet another reason Turbo Yoda is just the best! Takes something like tig welding(which as he said is an internet trolls paradise) and explains it in a manner that is to the point and accurate! Cheers mates!!
Hey Skid Factory, you should do another one of these types of videos where Alan goes over some of the mistakes he has made in his custom vehicle building lifetime, stories of what didn't work are just as interesting as stories of what does work! Cheers.
There's so much stuff in Alan's head he just needs to let some of it out for a run around sometimes. Even if it means that there will be... questions.
There's something about these run throughs by Al that, even though I already know the principles and techniques that involve some of these vids, I still end up watching the whole thing and feel like I've learnt something.
seeing Yoda & woody in the same room as Nik & Rich from Bad Obsession Motorsport would break youtube
yoda and nik would make an amazing build. woody and rich are just editors
Al, your exhaust welding is top notch! Beautiful seams!
Mate you are a proper aussie legend there isn't many mechanics/engine builders or engineers etc could care less about extra cost on customer builds 👍👍
Different things require different techniques. Wisdom that can be applied to all walks of life. These videos are great and The Skid Factory is my favourite automotive show a long with MCM and it's cool to see Benny making content. Got tired of Motortrend although I still watch, DeBoss is pretty cool still. But no one else is humble and making informative vids. Who else can say that at their job they watch vids on their lunch break to get better at their job and to relax. Cheers guys!
I sometimes used gas to try to purge my missus out of the room.
Gas has been used as a purging solution for a long time, perhaps even a final one.
Thanks for another very interesting video! Everything so well explained without much usesless blabla. I'm working now almost 20 years on BMWs for a living and still I'm deeply impressed by your skills and knowledge. And sure there'll be always someone out there in this world who's even better but also almost everytime these persons just focus on one thing. I'd love to see if all these "weldinggods" also have your knowledge and skills of fabricating a wiring loom, building an engine and so on - I doubt it highly. Greetings and hats off from germany!
Perfect explanation I’m in to the dairy industry I’m a dairy tech and I do a lot of welding and your explanation it’s on point! Just the inside of the food grad it’s more clean it’s the same color as the pipe but again food grade we use more argon flow! Big 👍🏻 love to here you explaining!
For someone whose just learning to tig, many valuable lessons! Keep up the awesome work!
Al, thanks again. I am a total novice who doesn't work on cars but have a huge appreciation for craftsmanship. Your no nonsense and pragmatic approach is a breathe of fresh air in these days of overwrought and prissy want-to-bes. Keep it up sir.
Al, an excellent demonstration and explanation on the different methods of TIG welding and their different uses. I have had major fabrication work carried out on an offroad buggy constructed of chrome moly tubing by a mate who specialises in the food grade side of welding and his work is something to behold as he still chose to purge certain parts of the chassis around the engine area and this explains clearly to me why he did just that. Yes he was not cheap but the end result has other welders in amazement at the quality of the work mentioning overkill but if ever I turn this thing onto it's lid I am happy that he has made the strongest possible welds so cheap insurance in my opinion. An excellent basic tech video to anybody starting out on TIG welding I reckon.
Amazing how down to earth al is best aussie out there 👍 cheers boy’s
Hi , I was a ticketed 4703 dairy back purged welder over 25 years ago , good video for car guys , one thing i could add would be is, argon is heavier than air so think about it filling the pipe and bleeding out the hole and watch your flow rating on the purge as it will bellow out your weld making it look like you don't need any filler wire , when welding , and then internally it will be undercut outwards , hope that makes sense. Cheers Mate.
keep blurtin it out!!!! I found this super-informative for my non-welding mind to absorb.....At least now I know why my "custom stainless headers" look the way they do....a bit of slightly sloppy fab.....Anyway, thanks for another great episode!...many love, much props.....
Been welding ferrous for years, but learned something new today, excellent presentation thanks -
This video was great. It provided me with answers to questions I have had for a while. I like all of your content but when you take the time to explain something like this is is really appreciated. Thanks to Al and Woody from Canada.
I do love to listen All rant about any stuff. You are awesome mate
From what I've observed from another CZcamsr who does everything on a tight budget, metal coat hangers can be used instead of welding wire for welding. He gets some damn good results from it, so it seems to work well. He's also from my home province, Nova Scotia, Canada.
You've gotta love Al. His dry sense of humour and no nonsense approach is what makes his take on things so infectious. I should also mention that he's very good at what he does. Great channel guys.
Hey Al & woody I'm a boilermaker/welder by trade. Instead of argon gas for the purge line you can also use helium gas which works as well. It will save you some money. Keep up the good work lads 🤙
Plus I want to see a quick tech with Al talking like a chipmunk!
But Al is using his smaller tank as a back up bottle for welding... so maybe it´s reasonable for him to use argon in it too? Anyways... good info Brendan...
helium supplies are dwindling, it's probably expensive in AU also.
@@brandoncharley3070 Nitrogen is also a good option for non-critical applications.
As one of those Trained welders, I reckon you do a great Job that is "Fit for purpose" and your explanation would have been fine if you had have stopped @1:39. The Pedants don't need to be fed.
Here, here
Also his bog standard fuse weld was bloody clean
Al, You did a great job! We used C02 as a purge gas. It is liquid in the bottle then comes out as a vapor and lasts a long time. Argon gas is expensive here in the states too.
Words cannot express how badly I'd like to be your apprentice, Al. You have so much knowledge about cars and I want some of it.
And none of the workshops around here take apprentices.
Woody getting nervous and won't heart you lol :D
@@felipegacitua4451 Nah, it's cool man. Woody's a qualified mechanic as well and I have no doubt he'd be able to teach me heaps too.
Awesome job. Great to actually see the three welds compared. Always love watching you fuse weld!
Al your quick tech are fantastic. I appreciate every one of them.
I learned so much today, thanks for doing these!
The fact that Al just says all this off the top of his head without a script shows how well he knows what he's talking about, only working professionals can cover a subject like that.
Thanks Al, I enjoy watching your Tech Tips.
Good Vid guys, I know nothing about welding but found this interesting 👍
I think you meant V-Log!
Love the quick tips!
That's because Dave still has a vhs collection.....
Thanks Al & Woody, another great informational ep. Cheers boys.
Thank you for a very informative video. I had no idea on purge welding and thank you for the education.
regards Bruce
I think al is my all time hero.
I like your no nonsense explanations. Subscribed.
Always enjoy the tech episodes 👍
I need my dump pipe to be able to handle baked beans too!
Fantastic! LOL!
Thanks for the knowledge Al!
This was really informative and I appreciate y'all posting it. I wish you could have gone into more detail on what sugaring was and why it is bad/causes problems in intakes, and why it is ok to not worry about it in exhausts. Thanks for helping educate the internet!
What a great video series! I love how effective yet informative the videos are. Thank you Al for Sharing your yoda wisdom and woody for filming and injecting the odd question when needed. Keep up the good work!
And this is why he is the Yoda. What a freaking legend. Great work explaining something that is very often poorly explained on the internets. Great companion video to Mike Finnegan's Video on purge welding the plumbing on his drag boat.
Hi guys you got this to a t I work for a welding supplies in Wales Swansea we sell Lincoln miller Esab kemppi . all I can add to this is I tell people to use a gas lens body the one with the mesh so the gas is more even spread or create a vortex to push the stuff out that you don’t want in there faster when purging but I always say if it works for you why change we also supply to a bakery manufacturer who has to abide by professional standards. tig welders always want the smallest items . We are in the middle of doing a mk3 Ford Capri with a 5.7 v8 and keep watching you videos for tips Thanks
I love these little "training" sessions from Al! He is very good at explaining things. It is also good to see how comfortable he has become doing this sort of thing. Cheers!
The best part is that he reasonably kindly bitch slaps the OCD ridden internet experts it to accepting the concept of common sense!
Al is so damn good that he cannot mess up, even on purpose!
Thanks for sharing and as always keep building👍
Amazing tech as always very insightful. Never tiged before only ever mig and stick. Love all the content you guys are legends 😎👍
Love the content you guys put out & quick tech is cool.
I have worked in Oil & Gas construction for many year & the technique used out there when welding "gas lines" is to build small argon dams inside the pipe, a mixture of high temp foam & plywood sandwitches & blow up heat bags.
Only reason I comment is it can save a lot of gas as only the area at the weld needs a shield, a small foam ply combo with the purge line stainless wire connecting another ply foam combo with a hole for the purge. connect a long piece of wire & pull it down the pipe to the next weld & off you go.
Some cooling between locations may help to not melt your purge rig!
Still quite quick, condensing years of experience and knowledge into an awesome 23min video.
Love everything you guys do, so interesting and so entertaining. Legendary team, as with MCM.
Never knew more about welding than after watching this video. Always a treat watching these type of videos
This is the best automotive use purging vs not purging welding explained video on youtube!!
Let's just take a minute to appreciate all of the awesome content that's coming out of the skid factory. Love these videos keep it up Al and Woody 👍👍
Real world experience Yoda and his wisdom. Thanks Al!
Awesome quick tech guys. Just started welding for automotive projects and this will help alot.
Cheers 👌
This was a good demonstration of the different techniques. Nice work guys!
im a old school boilermaker.you explained that well for what you missed its not even worth talking about,in the aplications you do its not going to matter a hoot,i avoid foor grade these days.love your channel man,woody your looking abit rough these days that ktm giving you dramas ha just jokes keep the good content coming
G'day Alan having spent 38yrs in the trade you did rather well at explaining the old KISS Theory😉🙂
Good on you🙂👍👍
Thanks for the knowledge drop, guys.
Fantastic explanation. Thanks, Al.
great show, thanks for the in-depth welding lesson/refresher.
Good explanation, loved watching it.
Thanks for the "blurt" Al. Very informative and entertaining, as always.
Awesome video mate! Thanks for sparking my interest in welding again. Gonna pull out my Tig rig and get practicing again 😎
Another great tech tip. Now I need to get my welds up to your 'non professional' standard.
don't we all mate..lol
Man this is so informative. Never tried welding in my life but thinking I might have a crack and learn as I go! Cheers lads
Take it slow... and find as much good info as you can... bad info will make you lose interest and fast!!!! Find someone that is kick arse in welding and get them to show you... let them setup the machine and see if you have the gift, this also shows you, when you weld you are capable... if it comes up crappy later.. you need to spend more time setting up, maybe a better machine... and never... ever stop using test pieces!!! Very satisfying fusing molten metal.....
"Quick" tech is 23 minutes! You guys are the greatest! More!!!
Thank you Alan for the tips !
Thanks for a great video and a informative explanation Al.
Highly informative, thanks lads.
Excellent video Al, weld looked perfect with no filter rod. Didn't know it could be accomplished so easily that way. Thanks
G’day Al, well explained. Cheers
Peter
I've only every tried welding an exhaust twice, I straight up burnt a whole in the material I was trying to weld lol... but I was mig welding and I "fixed it", 10/10 i'd recommend mig welding if you're a noob like me and just want your car to not sound faster than it really is anymore and you're tired of the muffler falling off because the make shift clamp you "engineered" keeps coming loose because the borla muffler you got for $40 isn't for your car but it sort of kinda fit in the right place. I had cut the pipping and the bends to line up with everything perfectly and that im really proud of that, but yeah, like you said Al, too much current but the hole isn't there anymore :) (2000 forester L), really looking forward to getting better over time and not put holes in things anymore lol, thank you for the tips turbo yoda … Failure story over, I have a legacy GT wagon like the liberty in the vid and super gramps and i'd love to see one of those build reviews on it!! its my dream car and im honestly glad im able to own one! great video once again guys... side question, did you guys run out of lemon squashes? haven't seen them in the last few episodes lol
finally a great explanation and rationale for and against the need to purge weld straight from Al's head! Awesome
Loving these Quick Tech videos.
Good job Al. This was a really good video.
Very descriptive and well explained. Well done.
You are a legend Al! (And woody) The not so quick tech is on point.
Thank you for these videos, I love this channel.
Epic as always AL and Woody.
Quick tech on maybe headwork if its even a thing for you guys, opening ports, purposes of making ports bigger, flows, ect maybe the people out there would like Als straight forward explanations.
Very nice. Very informative. Thank you.
Thanks for the tips m8s, great video.
Thanks for sharing the info!
Nobody got time for bacteria in your manifolds
Nope. A yeasty pipe aint no fun
Fantastically informative video, thank you!!
