Love the video nice bead
Thank you very much for demonstrating it’s not that difficult to bond galvanized to plate steel. Cool man thank you
For galvanize metal how do you set up the welder what is the volts and amps and wire speed supposed to be. For this metal
Both welds were good. Obviously prep. if you don't it spatters and it burns you 5 x that of steel/aluminum spatter.
How can you tell when the galvanised is ground off completely ?. Does shiny bare steel look different from polished zinc ?.
Hi Brian, thanks for watching.
There’s a slight change of colour that reveals the zinc has been adequately removed.
That may not be visible on the video. 👍
From my little experience ( i am surely not a real fabricator ) when I ground off the zinc with an angle grinder, the metal starts to spark when the zinc is ground off and reveals the clean steel underneath it. Can someone confirm if my theory is correct?
I use a wire brush on my grinder and the color of the clean steel is obvious once you get the zinc off.
The spatter produced by the first weld is unpleasant.
Anti spatter spray helps too.
Can we do tig welding for root pass in GI pipe to GI pipe butt joint
You can do anything you want to Arun.
I on the other hand don’t Tig weld.
But we can have a go together if you like .
I’m learning welding and today was the first time I touched galvanized steel... somehow the back of my pants right behind the knee caught the splatter.
The instructor and a few classmates with welding experience said that welding galvanized material sucks, I completely agree with them.
Obviously experience with it will make it better, but I got a hunch that it’s gonna always suck to work with.
EDIT: now that I’m further in the video and seeing the differences, I’d like to point out I DID NOT prep. I have a feeling he didn’t have us prep intentionally to show us how much of a difference it makes. Gotta learn the hard way I suppose, wish It didn’t mean I’d have a burn hole in my back of pant legs though.
Wait till you try overhead galvanized!
Bro I just started welding galvanized too lmao I didn’t prep either I have a burn mark from the splatter on my leg and it hurts like hell🤣
You have to learn what not to do then you can get better 😂
@@JoshMate-lz4hyIt’s possible to weld galvanized without prep. It’s not easy to learn. Short stickout, higher than average voltage. And a GOOD respirator. Do it in a production shop a lot. Overhead too.
Got Milk ? 🙂
Excellent camera work but could have been greatly improved if you had explained the settings on the welder and type of flux core used!
That's not flux core, he is using a gas mig, I'd say he is using .9mm mild steel wire.
read the title GMAW stands for gas metal arc welding which needs to clean off all the zinc at the join before you weld and weld indoors but if outdoors flux core is preferable although I would use .9mm flux core anyways - gas is too expensive and flux burns away more impurities as well as any zinc - I would even use 6011 s or 6013s stick weld as the metal is quite thick looks like about 4mm in the pipe and 10mm plate steel
I never enjoy speechless teaching but nice mig gun. Ran those and liked them.
I feel like the way you learn to be safe while welding, is by learning what happens when you’re being stupid.
What made me learn to wear long sleeves was stick. Had short sleeves, got a ton of spatter covering my arm, and got a nice little uneven sunburn. Hurt for a couple days. And now I don’t do that.
Similarly, my friend learned to keep a guard on his grinder after saying “it doesn’t even do anything” and proceeded to grind down one of his fingers almost cutting off the tendon. You could see it but he didn’t cut it.
He used the guard now.
First time I ever used a welder no one told me I needed a helmet. Proceeded welding for 5 hours. After being done within half an hour I was hospitalised. Arc eye is no joke.
Needless to say that helmet is always on
@@2ndrunraidshadowlegends631 bet you won’t do that again
@@svndwich977 nope not at all
I love it. This is like a silent movie 👍 🎉
Weld quality is certainly improved when removing the zinc, but the most important reason for removing the zinc is because of the serious health risks. Since the zinc is still on the inside of the pipe where you can’t reach with the grinder I would use acid to remove the zinc instead.
Or weld outside. Been doing it for near 40 years.
Yep that works too, but them safety-sally wankers would love that one 😂
Man, get a brain. Weld outside, and use a mask. Maybe use a blower outside. Sometimes I'm wondering how humanity even came so far.
😂😂 that tickled me lol
@@somborn even if they didn't follow any of that, they'd still live plenty of years to produce offspring. thus humanity continues and we're saved
Haha. Im know what is welding non Prep and Prep zinc coated parts but with tig 🤣🤣 More time I'm spend grinding tungsten than welding time if I'm forgot clean zinc 🤣🤣
Actually I'm starting learn Stick welding.
Regards 👍👍👍
That is the funny thing about welding, it’s 90% preparation and 10% welding LOL but you can see the difference in the video.
@@stanlysawicz9317 99% Persperation 1
Thanks for the video. Really appreciate it ❤
Lol, that was just awesome! I was thinking about those people with all these welding numbers that never help a person get to the job! Wait, another angle, hey another one! That was funny! Awesome solution to videos saying galvanized can't be welded! I have some emt pipe left from electrical and I'd rather recycle if I can (unrelated to that) and not have to go to the store searching for metal!
The metal welded! Ughhhhhh people!
Great demonstration
i got ptsd from watching no prep
Metal fume fever is no fun.
God damn you can weld!

Doesn’t that grind of the galvanized coating? I just started welding galvanized sheet metal and I would like a good weld but don’t wanna mess with the properties of the metal
Are you referring to the Corrosion protective properties of the metal Eddie, that you don’t want to mess with. Or other?
don't speak, let me guess.... what the hell !
Hi Earl 👋
Are You Using GAS Argon ???
What Brand And Model
Of Wire Are You Using ???
Amén.
Thanks for the video. We need more videos for understanding the fabrication process of structural steel
I weld galvanized steel everyday mig welding but no ventilation not real sure why and we can't grind anything off because of what it goes on for door's for the mines
When you get tired of puking, milk helps. Next time you remove the zink.
How to: weld in a library.... Shhhhhhhhh....
📚🤫
Love this video
That’s what I hate about galvanized metal. The amount of splatter
Hard wire is better for the real thin pieces a lot less splatter and nothing to really have to clean up
And here endeth the Lesson.
Good vid!
I got to see a optometrist .
😵💫
Would you turn up your power a little bit?
The sides dont look like they are penetrating enough?
Also, will it crack most of rhe time?
Personal preference and whatever you’re welding needs to be taken into consideration.
Haven’t watched the video Again to answer this, but my angle may need checking. Could be favouring the plate with regards to your visual on penetrating
Have u ever had to roll steel tubes and weld plates the end of the tube 1 handed? Its really hard
No, have never done this.
Why did you have to do it that way.?
Nice
Wao 😮😮
Was that a drag motion? When I try to drag with galvanized it’s all kinds of mess
Wire speed too much.
Thanks for watching 👍
Ive had good experience with 7014 rods and galvanized material
Hi Matthew. You prefer the 7014 for galvanized welding specifically, or just your go to rod for all applications?
thank you.
Thank you Michael.
I'm watching this video because I'm trying to figure out what's the best way to weld on my school bus.
Open the door when you do so.😉 🚌
@@TheMetalFabGuy No doubt. I enjoy my IQ points.
It’s okay to talk, we won’t mind….
… Try telling that to Charlie Chaplin.
I thought u had to use flux when welding galvanized for proper bonding
Thanks for watching John. Interesting point of view. I’ll look into it. If the zinc coating is ‘removed’ I would imagine that most welding processes would be adequate.
@@TheMetalFabGuy Most of the metal in our supply store is galvanized, i use flux cause i dont have gas bottles and plus i dont weld that much. I saw it on this video: ruclips.net/video/nrMxZKDb5dI/видео.html&ab_channel=Weld.com
@@TheMetalFabGuy Ive also noticed that not all galvanized metals are made equal. Expanded metal is a bitch to weld cause the zync is much thicker that square or round tubing. Idk if thats just my supplier. But yeah removing the zync makes any weld adequate. @6:49 u can see some porosity if im not blind lol
I agree. Some are definitely worse than others. Not something that I’ve extensively done or chosen to do. But most welder/fabricators have had to at some point. Welding galv where possible, is usually not by choice.
You’re not going blind. 😄😉
Thanks John.
Thanks for the link. I’ll take a look.
You must really know what your doing if you are welding on zinc
He is just welding on zinc plated, I have a friend who repairs sculptures from the 19th century that are pure zinc, it is an art to weld them....I weld ducting that is zinc coated, some are 500 mm x 750 mm, they are also 170-S6 wire, not sure the metric size. it is very difficult as the fit up is not always good, They are being joined to different size Ducts, so there is a lot of fitting in field with odd shapes [triangles, ect.] the weld metal actually sucks in some zinc which acts to protect it.....these are for outdoor install.
Now I’m legally blind..
Sorry to hear that Jesus.
could hear mig sounds, no voice.
That’s it Wesley 👍
I put on my CPAP to watch this.
Good work Dave.
Safety first.
What’s the difference?
You see no difference?
Is this considered brazing or welding ?
Welding Matthieu
I knew it by the way. One of my colleagues at work didn't believe me and I wanted to show him. In Canada there is no regulations against welding galvanized steel in a work environment so I've been doing it almost every day for the past 15 years. They never told us to stay away from the fumes lol.
Make sure you have a mask and / or good ventilation 👍
Welded galv pipe to steel rebar, over 20 yrs ago, just stick welding with mild steel rod all over my debris trailer. Been holding up fine. Gotta go deep.
Thanks for your comments Mike.
Nice demo!
Thanks for watching Eric.
What are your settings? Thanks!

Thanks for your advice 👍
Why the need to talk? Remember, a picture is worth a thousand words! IMHO, the video tells you all you need to know 👍
Can you talk?
Hi Mike.
Thanks for taking the time to contact me with your question.
Yes I can. How can I help you?
