lesson on welding thin steel,

[davemiii]

Restolad, wtf happened? I watched this vid like 2 and a half years ago back when i was starting to teach myself welding, and now it's got 128K views? Nice job dude! (And I dig the background music, screw it, and did that Brit aero engineer never look up wtf 6061 is?) (Mech Eng here, 20 years experience).

[krssnoop]

thanks for the tips mate

[therigger66]

Much appreciated, heat sink worked a treat!

[deuce217]

Thanks for sharing!

[SpringCityMotorsport]

Thanks for the great tip. 

[omarks]

Thanks, very clear and useful

[gekkomaster1]

exelent video,especially because you kept it short and simple :)

the best thing to have when welding really thin materials is a fully adjustable mig welder, so you can adjust the voltage and wire-feed independently.

[justjooniin]

Thanks for the tip, haven't thought of that before.

[75bAdam75b]

6 people tryed this and this and weilded the copper to there work lol

[xXBuckOFiveXx]

Great tip!!

[walshop100]

great tip thanks. also wondering what size wire you would use for a panel like that?

[restolad]

@walshop100 i use .6 solid mig wire and CO2 gas Restolad

[Mantas840]

@restolad I am in NZ and was wondering where u buy CO2 for mig? My argoshield is nearly finished and it's bloody expensive.

[markschellhaas]

I make my spots tiny like a tap on the trigger makes them easy to grind . the quicker on the trigger the better the grind. I tend to forget my copper paddle though. if you practice it you can make them as small as a pin top. aka air soft bb or smaller. they also keep the heat down. I weld them on the side that shows because the finished product tends to be smother for finish. If you like check out little river hot rods .com and see our work

[robotmotor]

hello please tell answer me did this machine need bottle of gas and if i dont found it and what type of gas she need thanks

[DesertDigger1]

The back ground music is distracting.

[BuickDoc]

My problem with mig welding is that the weld bead is so hard that it is difficult to grind without overheating the panel. Do you have any suggestions? Is it the wire?

[restolad]

@BuickDoc your right mig is hard to grind - I use a 3m or blue corps flexable grinding wheel

watch my surface rust removal video i am using them there. they are the best and make short work of of a mig weld.

[lynel1985]

@restolad i agree those blue coloured overlapping flap wheel looking things work wonders

[TheMartinto]

awesome i learned something new man thanks keep it comming!

[SportSuperBigblock]

Very good tip for a beguiner like me. Guys like you, who share their knowledge, make a lot of difference in a pretty harsh and selfish world. Thanks a lot from Brazil.

[Metalunique]

Thanx for sharing. I'm a new welder and I've been pretty much teaching myself through trial and error using all kinds of scrap metal. I going to try this technique because I'm always having trouble with thin materials.

[fleshDevice]

Hey Bazza Some good you tube dude not as many hits as 2 girls 1 cup but lots more than me TFC

[kuhlka]

A skilled welder could also oxy-acetylene weld that seam without much filler. Steel is cake compared to similar gauge aluminum. For low-budget DIY people, this is a great video, but GMAW (MIG/wire) heats and cools the metal too quickly for it to be ideal for high-end thin bodywork. Oxy is ideal, especially on aluminum. GTAW/Tig is a close second. At least that's what I was taught by Ron Fournier up in Detroit.

[ekfinn]

Restolad: Can I make a suggestion? Good call on the heat sink, but for such a thin material, and a thin crack, you could have maintained a constant and faster travel down the crack after you got your initial tack. This would have made the bead much flatter, reducing the amount of sanding you had to do.

Also, a crack that small, if you get a TIG setup going, you can take small hair fractures like that and weld them without filler, or very little filler.

[restolad]

@ekfinn Your feed back lets me know, that seasoned trades people are waching my videos also . like you I am tig crazy it my first choice for panel steel - this demo like all my lesson is targeted for the folks in there garages at home, it more likely they have a mig rather than tig thanks for watching my stuff Restolad.

[ekfinn]

@restolad Glad to see others are spreading the good word of skilled trades. Keep up the good fight... the more people we get to pick up a set of hand tools, the greater chance our species has.

Oh yeah, if you ever need to make your way over here to the states, let me know. I'll welcome and introduce you to some real football, mate. Cheers.

[restolad]

ekfinn ouch me 5" 8 and 75Kg a game of grid iron, would crush every bone in my body, would love to be at the super bowl one day - let you know if i make the journey, Restolad

[asleeperj]

@restolad what kind of welder do you have? I know it is a mig, but what brand, and type.

[restolad]

@asleeperj it is a c i g weld 130 amp . it is powered by primary & secondary windings - this is old school .

one day i will up grade to inverter powered mig welder Restolad

[Bartezz12345]

@restolad Thanx for your vids! All I can get my hands on is a MIG setup. Never taken any welding courses so vids like yours really help!

[125pob]

really can nobody weld on you tube?ill upload a video soon.everything from 0.3mm to 50mm gauge,how to fill gaps and how to rework bad welds with welds

[cwlewis123]

@125pob

1 week later...still no vids

[cigarcaptain]

I always look forward to your videos. , I am building a hot rod and you have been a blessing . really great videos. You really have talent, thanks for sharing.

[HDXFH]

Great advice, Your technique is very professional

[chrisrudy1969]

Thanks for the info!

[lonebiker23]

excellent video. thanks for taking the time to show us that secret trick. i never thought of that.

[nqtraderman]

Very useful video, thanks for demonstrating, I will definitely use that trick

[WarlDogg]

I like you guys from NZ your very logical and descriptive and I love the work you guys do on your cars :)

[smallenginemods]

thanks man! ive been searching on here on how to weld sheet metal without burnin through, favorited and i sub! good job and keep up the great work

[steveforfuntimes]

good video nice tip on how to weld thin sheet using a heat sink, Ive never used a heat sink but will in the future many thanks for your good info... Steve

[thisoldtoolshed1]

Never thought about using a heat sink. Thanks a bunch for the lesson.

thisoldtoolshed

[berylak47]

Nice vid, but you need to kill the music. It is sort of distracting.

[wezmac]

good work, cheers

[Bintumani88]

Restolad, Thanks for the tip. I'm happy to have come across it as I prepare to weld some new body parts on a Vanagon I'm restoring. I have a little tig welder, 80 amp. How does one decide the size of welder to use?

[FREEHANDILLUSTRATOR]

thanks mate

[Em1nenceFr0nt]

Bad Ass advice. I have some old 65 VW Fenders that have a split in them, this was an excellent tip. I will put this to use immediately.

[layin22s]

It would of been a good video but you really needed to turn down the radio. I could barely hear you. Also personally for a small crack like that I would of used a tig.

[lbccwelderman]

I like the video thanks for the advice. I hope you make more .

[hitman00007]

Thanks for the tip, you helped me a lot, nothing like buying an expensive welder and not knowing how to weld.

[07fercho]

to what aton said... i dont care if is alloy or not as longes it does the job its fine to me Resto thanks for all the tips ur a great guy;). and u remind me to the transporter haha later bro and good luck. adios amigo.

[bunning63]

Great vids mate, takes a Kiwi to do it. As you say once copper is no longer pure the following applies,

"Copper alloys are metal alloys that have copper as their principal component"

Quess you up 'Taranaki'?, cheers.

[antonyaiken]

not to make a fool out of you or anything. but copper and aluminium are not alloys.... steel is the alloy.

copper is an element. as is aluminium. steel is not on the periodic table, its an amalgomation of Iron and carbon.

[restolad]

anton !!!! do you have a serious brain injury, ? your comments on other peoples videos and mine are harsh, copper and aluminum refined for industrial use,are not pure there fore they are alloys,

your knowledge of things mechanical, has made you socially retarded, and leave you looking very foolish.

time to grow up buddy .

Try some some positive affirmation, towards those around you , then i will guarantee your circle of friends will increase, and people might like to be around you .

[antonyaiken]

@restolad my knowledge of things mechanical?... i am an aeronautical engineer for the royal air force and have 9 years of previous mechanical background to boot. what i have said in my previous post is 100% accurate.

it wasnt meant to be harsh but i wanted to make a correction to you saying copper is an alloy. when clearly, it isnt.

i appologise for sounding that way,i couldnt give a rats arse what people in cyber space think of me though..

[EMFinduction]

@antonyaiken must be why the brits have so many maintenance issues with their birds. You'd be hard pressed to find pure elemental copper or aluminum for purchase. There is nothing structural on your typhoons that are not an alloy of one type or another. Most copper available to consumers today is an alloy of copper and zinc of varying degrees from brass 70Cu/30Zn clear up to 99.9% copper for construction and electrical work and that's mostly annealed... not 100%... so still an alloy.

[molotov3x3]

@restolad antonyaiken reallllllllllllllllly should stick to his cake decorations lol

[knightriderutube]

@restolad

"socially retarded" ????

Not cool in your response restolad, just not cool ....

[3habaneros]

@antonyaiken the only one that looks like a fool is you dude

[spacepine]

@antonyaiken You are correct, copper and aluminium are not alloys, they are alloying elements. However, as restolad pointed out in his comment, copper and aluminium from an industrial standpoint are mainly alloys. There are some applications where the metals would not be an alloy, like 99.9999% pure oxygen-free copper (OFC) wire, used for speaker cables. The only fault is in the semantics. Alloyed metals instead of alloyed steels is what he should have said. His heat sinks are alloyed metals.

[DeepSeaTadpole]

Cool trick. Thanks! That also ensures that your pieces are in-line accurately.

[seasonedtoker]

so when you grind or file that weld flush with the panel, how do you avoid breaking the weld? what would be the difference if you put a bead on the back side and let it penetrate so that it fills all the gaps on the front side? is there any difference? thanks!

[malkooth]

Excellent video. Quite the skilled craftsman there.

[jimm187]

bro i was jst wondering wats ur setup on tha welding machine

[devilsbox]

Very helpful, man. Thanks!

[ImRamro]

Thanks for the tip!

[divyajnana]

Resto, thank for the great tip and a very nice vid too.

What was the wire thickness you were using?

Right now I have .035 and think it might be a bit too hefty.

[Mooseboy240]

accents make your welds badass

[GookStomper]

why did nt u weld it from the other side the hidden side.

[Norcalbowhunter]

@GookStomper He is going to grind it down and paint it. In the end it won't make much of a difference how he did it. I do get what you are saying though, if he did it the other way he would of had much less work hiding it. But in the end, you wont be able to notice it if you give it the proper touch up.

[Jaket2000]

When I got to use the MIG welder for the first time in welding shop I allmost had toomuch fun using it.

[dr230]

Thanks for uploading this demo, restolad! I managed to make a small repair to thin metal with no problems at all!

Your vids are always very helpful!

[courtneyhook]

Hey Resto, what type of mig welder are you using, and is it gas or flux core? I have a little Miller 120volt setup that uses either gas or flux core wire. What size wire? Thanks!

[restolad]

@courtneyhook this welder is a cigweld 135. i am useing Co2 gas and .6 solid wire

[diesalweasel]

@restolad hay resto i'm very new to all this i'm only ever tacked a few nuts on to steel that about all lol

what mig wire would you recamen for someone like me as a beginner the thickness i like the tip about the copper plate. the same method is used in soldering to get the heat away from the circuit board lol i'm quite good at soldering. but fancy something new to try regards james from uk

[artifact2008]

Good tip! Thank you keep up the good work

[live4muslc]

no music and less cam movement please!!!

[pansimon]

Thank you soooo much :) I sometimes get cracks on steelpans when making them. Normally I solder with silver with small ones but will try this tip soon!

[benrevs]

@tbirdpimp07... He isn't British you douche.

[keyko555]

Excellent presentation, thanks for posting.

[breezebro]

Very good info. This is the type of welding tip that is hard to find on YouTube.

[tbirdpimp07]

british people music sounds like 80s music to me yuck lol

[Visionarydave444]

Very informative, thank you very much for posting this.

[KrisKustomPaint]

@restolad Its hammer welding check out how ferrari, and other coach built bodies are made. there are no good videos on you tube. I have some some welding to do on my '49 ford I'll make a video. Basically you hot plannish the weld as you go to cancel the shrinkage due to welding. And being a red hot gas weld its so butter soft you wouldn't believe it 5 light smacks per inch, give or take, and the weld is flat, smoth, and even with the surrounding metal. Its sorta like magic. but nothing special.

[restolad]

Yes i first learnt to weld with oxy , your first description to me of this was vague, - i still recommend tig or mig because unlike old Ferraris, manufactures started using high carbon steel from about 1968 on, and gas welding burns out the carbon, leaving the repair structurally unsound. and a lot of restoration now days is on these unibody type cars - if i restored a Dino then gas weld and brazing would be the correct method .

[jcbrowns]

Thanks buddy.

Your videos are really informative, I appreciate them. Keep 'em coming!

[ProcessRacing29]

Thanks! I got a 2" patch I got to do on rear fender. Got to get me some copper or brass!

[surf403]

Thank you restolad!! I really learn from your videos and appreciate your taking the time to help people you dont even know!

[snakeoil24]

Restolad thanks alot I still learn alot never tried the aluminum.

[ScottysDetailing]

i always wondered how to weld thin metal thanks.

[hitcb]

i dunno if it matter on thin stuff but you should drill a hole at the end of the crack as to keep it from spreading later

[miinipilduja]

Like to watch youre videos, learning new useful stuff :D

[jacobhuns]

Thank you for your video! Very informative. I am trying to learn as much as I can so that I can restore a car I own. Many of the people I know doing restoration, prefer OXY welding so they can hammer and dolly the weld. MIG, they say, is brittle and cracks. I have heard you can anneal a MIG weld. Is that so? Which method do you use for larger welds? How do you make the weld flat? Thanks again!

[restolad]

You ask questions that cant be answered with a short reply, Older tradesmen perfer Oxy welding , but you get lots of distortion, i replaced my oxy set with a tig welder !! (skip welding on long butt welds) This demonstration with mig, was metal finished ,(hammered and filed smooth) i have never had problems with cracking and brittleness,with mig: Welds are made flat, by dressing with a hammer and dolly, a skill that takes lots of practice, and a understanding of how metal behaves.

[KrisKustomPaint]

@restolad Mig welding causes way more distortion than Oxy welding, Oxy has a larger heat affect zone but in the end thats what helps you. tig has a large HAZ than mig and also causes less distortion than mig. If you try all three you will see why the seasoned welders prefer oxy welding for sheet metal, you can planish the weld absolutely flat with very little hammering, and can weld continuously with out having to wait for the metal to cool.

[Trendyrapslut]

i understand the whole backing plate as heat absorption, but since copper is really good, why would you use the thick steel if it's not good?
