HOW TO MIG WELD THICK STEEL TO THIN STEEL

In this video I'm showing you a little technique I've learned for welding thicker steel to sheet metal.
I use this technique a lot when doing fabrication work on cars.
This was filmed using my canon 200d amzn.to/2DZIfgZ
Thanks Matt

[@anthonyscott16]

This is definitely going to be a gamechanger for a lot of us. Thanks for sharing your skills Bro.

[@DFEUERMAN]

Ali G got skillz!

[@lesliedickinson198]

A really helpful video as I'm in a large learning curve with my project MK 5 transit, I've done work on it already but you can never learn enough is my motto and these helpful tips give confidence to tackle more complex welding

[@shannonlawsonnashville]

I was running into this issue recently. The thought had crossed my mind to do something similar as to what you’ve demonstrated here, but I don’t have the skill that you do. Thank you for this instruction. Very helpful

[@Topper-gf8xl]

That's a great technique, thanks for sharing. I have to do floor pans on my Studebaker and will be adding seat belt anchors, so this is a perfect way to weld them in.

[@ZachMontizor]

Exactly what I needed to see for my home project! Thank you for the great vid!

[@garymucher9590]

Nice techniques and lesson. Thanks!

[@kramer26]

Yet another useful and informative video! Great content Matt, keep them coming...

[@rsbharley4766]

Great video matt, learning lots. Cheers

[@stefanm67]

Thanks so much! Exactly what I needed to know on a problem which has been causing me some grief. Excellent vid.

[@hellonwheels341]

Great idea and technique. I just completed some repairs and now I know why I had my issues with different size metals. I should have watched this.

[@thebandit4393]

Thank you for the video and explanation! Very helpful.

[@bidders77]

Just bought a sip t136 mig gas/gasless welder to fix up my mini that's been in my garage for the last 10 years and I think your channel is going to be awesome to help me out.

[@dave8599]

Thank you. You are an excellent instructor.

[@mustanglover4945]

Great lesson...I’ll put this in the ole memory bank for my upcoming restoration work. Thanks!

[@aerocam2]

Thank you, I picked up several good tips. Much appreciated.

[@timallen6025]

Very nicely explained and demo’ed , thx you 👍

[@bruceb3786]

Great tips and technique ! I too try different things, but having someone actually SHOW me a bad result AND a good result makes me feel like I am cheating !! Thanks so much.

[@Urchfab]

Happy to help, Cheers

[@trebushett2079]

Excellent tutorial.

[@eastanglianmagneteers3279]

Brilliant job again mate. Hopefully I will pick up on your talent 😊👍

[@dull_boy_274]

thank you for sharing. this will be very helpful!! nice work

[@D4VE26]

Cheers matt... religously watch the mungrel build.. am now welding in some spreader plates for a roll cage in my mini and am welding thick stuff to 1.2 and 0.8 so thought id google it.. and boom urchfabs 1st to come up, cheers again 👍

[@bonscotty67]

Perfect lesson for welding the plates I have to sit where my door handles were! Thank you!

[@leep6875]

hi mate, just found your channel and love what your doing, and picked up loads of good ideas and techniques

[@Urchfab]

Thanks, that's good to hear

[@KelseyWildstone]

Great video! This is what I was searching for ;)

[@JMo268]

Thanks man I needed exactly this.

[@timsexton8146]

Great job. I will practice that technique. Keep up your good work

[@ishimishi2353]

Wow it's useful thanks

[@jayhilliard4365]

Excellent. Thanks for sharing

[@austingupton8829]

Thank you for the video! Gonna be using this knowledge real soon🙂

[@roberty21]

Very helpful, you do by far the best welding videos on KZbin thanks for taking the time

[@joevangorder1006]

Man I really wish I saw this sooner but in my haste to get that flange on a muffler, my confidence was greater than my skill or knowledge lol. Came out okay with only one blow through that I was able to fill but I definitely would've practiced with a similar jig you used for your demo. Thanks for talking the time to show us though!

[@petemacrae5982]

You got that down.Nice looking weld. Thanks for the tip.

[@Urchfab]

Thanks

[@NialPowerCork]

Really useful video, thanks.

[@hobohacker258]

Before I got a plasma I actually used my mig to cut sheet metal ( Yes, very crudely, but it worked) Good video. Need to drop the TIG torch and go back to learning/figuring out mig

[@terencejay8845]

Nice work. I'm struggling with my first welding job; welding rear cross-member to floor pan (broken bolt that can't be removed..) with a stick welder. Not the best to start on! So far I've tried many settings but I still can't get it. Practicing welding 1mm steel plate to old brake discs, but I'm blowing holes every time, or the plate just pulls right off. So far, I'm down to 20A. I'll try this method next, thanks. ( I should have bought a mig welder.. )

[@godofawsome03]

Great lesson. Thanks

[@magwamagwa45110]

great video just the info I needed now to practice that way of dragging it back up thanks..

[@Bettinasisrg]

Awesome, totally awesome! Thanks!

[@thomasvilhar7529]

Great video. Thanks.

[@stevesmith3556]

Great video! I figured this out the hard way. The plus side.... I figured out how to weld up the holes I made too. 😋

[@1981bundy]

Great clip! Thanks!

[@endeavour2127]

Great video! Thanks!

[@justinfletcher779]

Great video, thank you.

[@jw200]

Exactly what i needed. Im gonna weld rear subframe mounting reinforcements to my BMW E36. Thats the welding i have to do. Thanks

[@nickpruno]

I have to do the same thing... On a 46

[@DD-it1th]

How did that go?

[@bfpeake933]

can't tell ya how much I appreciate this, thanks. Maybe some more on the #'s you used? Voltage, speed, and Inductance which no one ever seems to want to talk about? lol... teaching my self, so go figure

[@Kaizer357]

I've got the Lincoln 210 MP, quite the top end of the line welder but if you were to get your hands on one; the machine once set up, you can set the gauge of thicknesses and dial in the voltages and feed rate for the MIG. Thin metal like pipes and sheet metal usually take lower voltages due to the thickness but feed rate a bit higher so you don't blow through it. Been teaching myself with practice how to weld MIG and stick, on and off for 6 yrs. Hope you're getting better at it though.

[@kawshalyakarunaratne9172]

thank you for the great video !!

[@adamcrei88]

Hey man vary helpful what were the settings on the welder Max or Min and what was the feed speed of the wire for the machine to do that weld. Thanks.

[@mikebonge7206]

Damn nice work

[@TommyTen10]

Very useful, cheers.

[@Lewiseyers]

Nice vids buddy, subscribed

[@johnmacmillan627]

Very helpful. what were your settings?

[@willags]

great vids just starting to practice welding, probably a stupid question. how do you remedy if you do blow through or is it a case of just dont blow through.. cheers dude

[@jonathancolling2284]

Another top video mate and not a sausage in sight 👍🤣

[@Urchfab]

I've got another vid planned that will include a sausage

[@jonathancolling2284]

Urchfab: Good to hear 👍 😆

[@hobohacker258]

V 8 bangers and mash? :)

[@macymunson83]

really impressive!

[@MartinMcMartin]

This has really helped me to not blow holes in things.

[@Urchfab]

Awesome

[@juanrondon3519]

That was art work holy hell

[@Chad_N_Stacey_Hopson]

What settings are you using?? Great vid bro

[@thebrothers3971]

Hi Matt, would you use the same principles when wanting to weld a nut to a thin plate?

[@brentsmith5647]

Brilliant video thank u ❤️👀👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

[@slawomirlesniewski3321]

Thx mate. What if you have it up side down? Sometimes on the cars you need to weld in thick material uder the thin panel, gravity is against you. What would be your advice?

[@Mahtt]

How would you go about with an overhead? Same technique? Welding in reinforcement plates for the subframe of my rear end of an E46 upside down on jacks lol. Dealing with 18 gauge sheet metal welding on 14 gauge plates.

[@DD-it1th]

Brilliant 👍🏿

[@rusosure7]

Damn. You did that freehand? I'm really jealous!

[@dave8599]

Also I might add that weld thru primer is oft desirable when metal is doubled. The type of weld thru primer and its thickness can make a difference in welding parameters. it has to be done right

[@shorttime6264]

GRRREAT! Thxs!

[@beznich]

Very helpful information, thank you for sharing and taking the time to teach others! I had a question about technique. At 2:30 you talk about how to aim the wire at the top corner and let the puddle fall to the sheet metal to weld. How would you weld it, if the metals were reserved (meaning the sheet metal was above the thicker metal). For example I replaced torque boxes in a Mustang with an adjustable set made with 1/8” (.125 or 11 gauge) and 1/4” (.250 or 3 gauge) steel and I need to weld part of the floor which is thin sheet metal, to some of the top edges of the 1/8” plate. I essentially need to do what you are showing but I somehow need to push the puddle up which is beyond my skill set and knowledge, lol. Any tips or tricks you can share with me on that?

[@randylarson3823]

[@yourlocalalexis4578]

i was wondering what the trick was...thank you for the tip.

[@wearegame777]

Cool! What if your thicker piece is on the bottom?

[@endurolife7898]

Any considerations come to mind regarding applying this technique with Flux-Core?

[@johncooper7242]

very helpful thank you. I would love to see someone weld some thin to thick car panels together that are covered in rust and dirt and in a confined space.......as they are in the real World like the seat belt mounting points on a Ford Focus . They usually look like they have been rusting at the bottom of the ocean for 50 years

[@Impulse_Guy]

The best way to deal with that sort of situation is to make it less of a confined space. Don't be scared of chopping good metal out to gain more access to clean up/remove rusty metal. It can actually be easier to make up a few more sections to weld in that you've cut out for access then it is to struggle and do a shit job because you can't get access. The end of the inner sill near the axle mount on older ford's is a prime Example. It's easier to cut out the outer sill section and repair it from there than to struggle trying to repair it from the back, you won't be having to do it again the following year that way either because you can get rid of all the rust first time.

[@kik0013]

So many questions , was this a gas or gas less mig , what wire size did he use , and what speed , ....

[@haregeorge7172]

Are you able to put the camera through a Mask in a demonstration like this to see what your seeing when your welding? These are awesome videos by the way

[@Shakerhood69]

Awesome

[@trun6415]

How would you do do this vertically on an inside corner? Need to weld a 3mm box into the corner of car Interior

[@chetankumar2405]

What is the welding thickness required for 3mm plate in MIG welding........?

[@RaulAdams]

what was your wire speed and voltage?

[@ozwylde1]

Thanks.

[@Rsenior1981]

Beautiful welds! What welder are you using and what settings?

[@JereYaps]

I think he is using the right settings for the thicker metal.

[@earlwagner5940]

@@JereYaps He must be, I've tried setting for the thinner metal and that doesn't work.

[@williamhall2386]

is the welder set for the larger plate or the thinner sheet metal? I scrubbed back through the video, but can't really find it mentioned

[@Urchfab]

Set for the thicker material.

[@dalltex]

Excellent info. What about something that isn’t 4 times the thickness. What about 2 mm welded to 4 mm? Same? There is definitely a learning curve for me. Thanks for the vid.

[@Urchfab]

Same deal, Cheers

[@castintime6245]

7 people that disliked this video are dead inside......great video! Very helpful :)

[@MartinMcMartin]

What I am curious about, is welding thin panel onto thicker steel, but not on an edge but in the middle of the plate, if that makes sense?

[@Urchfab]

Yeh I think i know what your saying bud, just use the same technique keeping the puddle directed on the thicker then moving it onto the thinner, you should have much less of a problem doing it that way round with the thicker underneath.

[@bobm2637]

The video is informative. Thank you. But maybe picking up the pace is a good idea.

[@JOEGGGJOE]

Good video. Rubber coated gloves for welding, interesting. Ha

[@Urchfab]

I swap them out for some furry ones when things get hot. Cheers

[@NATUREPRABA]

how to increase the thickness of metal pipe

[@utahlakewaterfowlassociati996]

Why not turn down your voltage and wire speed?

[@brandonblake9540]

Back it up with a heat sink when possible

[@AnonYmous-qg4ph]

Just turn the welder down, after all , it's only as stong as the base plate.

[@kena658]

You're a very good welder but wtf with those rubber gloves😆

[@richardhalsey6049]

Cursive e's are a lot easier

[@whitefox9]

Its nice talking when you can afford the best of every tool A good welding machine is expensive and it does a perfect job without much fuss

[@niemdan]

We really need to separate the UK’s KZbin and the U.S.

[@robbs96]

Why? I mean thank god its not. I have got so much great information over the years from guys from Ireland, England, and even outside of the UK.

[@brandonheselton3569]

You have GOT TO STOP rubbing, scratching, tapping and clapping your hands. All that crap is so annoying I can't stand to watch the full video.

[@davidrichards3605]

It may be worth to say that these techniques are ok for welding cars but would not be correct for critical structural welds. Also please, please get the terminology right for welding steels, it is MAG welding not MIG - we are not Americans who don't seem to know any better.

[@Urchfab]

I use this technique for welding roll cages into race cars which is 100% a critical application, I have never had the need to use this method on anything structural as 1mm sheet metal isn't generally used. I'm interested to know what technique you would use for welding 3mm to 1mm sheet metal in a critical structural application. As for calling it mag welding although its correct all that will do is get me loads of questions asking what the difference is between the two, which is essentially nothing other than calling it mag to point out that Co2 is not Inert. Also 90% of my views come from America. Cheers Matt

[@davidrichards3605]

I agree that in the material range of 1 to 3 mm that technique is not so critical as you will get sufficient fusion and penetration almost no matter what you do - after all you only need 1 mm of fusion to match the thinner section. When you go to thicker sections and greater weld quality requirements then a using solid wire then for instance you would not drag the weld for good technical reasons. As for the terminology, I agree the stupid and ignorant can call something anything what they want but when it gets to technical matters in any engineering discipline knowingly using the incorrect name is beyond my comprehension, its like saying its Pneumatic instead of Hydraulic! If it gets you lots of questions, good, be different, educate them.
