Welding the Dreaded Galvanized Steel

Welding galvanized steel with .030 ER70S-6 with C-25 gas. This process is safe to do, it has been proven that zinc is not a carcinogen.
Welding galvanized affects everyone differently, you can experience mild nausea after welding for a prolonged time.
The process is done around the world and done on a mass scale.
Zinc is less noble than carbon steel, this means that the zinc will act as a sacrificial layer and will corrode before the carbon steel creating a long lasting corrosion barrier. Zinc is much less expensive than aluminum and stainless steel.

We weld galvanized steel every day non prepped. It's an art to get good welds. We do waterproof welds on it too.

started welding at 12 and never new about the evil's of galvanized until I was like 20 so I think it helped me like a suplement.

Thanks Bro. I've been welding for over 17 years, on the ship yards, Fab Shops, Mig, Stick flux core etc.., Just can't remember all the parameters for every process. To brush up before a Weld test, I 'll definitely tune in. You got a new subscriber here! Thanks again Bro, keep it going.

Zinc will not remain a vapor in the atmosphere.
Zinc vaporizes at 1600* F which occurs as soon as I pull the trigger. When vaporized Zinc comes in contact with oxygen it turns into Zinc Oxide which is a fine white powder. The fine white powder is present on the perimeter of all my welds. Been welding galvanized tubing for 2 decades.

I had zinc poisoning once, was laid out for a week with a bad cough, migraine etc

eating something and smoking it are two different things one goes in the lungs and one in the stomach you would not smoke that potato wouldya...

I welded galv pipe, or was in close proximity to welding almost daily for maybe 5 years just fine until one day I got so sick I almost called 911. 15 years later, I’ve had it maybe a dozen more times like that. My sensitivity to it has become increasingly noticeable. Can weld raw steel all day no problem. But have to limit myself to 2hr sessions or it’ll kick in. Not sure what it’s all about, I just know it’s a real thing. Now I always weld with shop doors open, and am way better at holding my breath. The milk thing doesn’t seem to have an effect.

If you have to tack a few inches of galv. sheet the fumes aren't likely to cause much annoyance, but you wouldn't catch me doing any serious repair on galvanized steel parts without either having it cleaned off from both sides of the joint or a half-mask respirator to keep the junk out of my lungs.

I did fairly-regular repairs on galvanized traffic lighting, hot-dipped galv on metal ranging from 11-ga up through half-inch plus, and there's a noticeable difference on how you feel the day after if you don't wear your ppe.

One should always wear a good welding respirator with 3m filters preferred when welding, grinding or cutting other than when your only making small tacks!

You telling me I haven't been galvanized poisoned? Hilarious

[donaldviszneki]

That green thing at 1:23 looks to me like it's been anodized, not galvanized or any kind of zinc coating.

How or can you weld galvanize plate on body of car???

[harrygilbert]

If I spend time can I wire brush the sheet and get a decent outcome

[bennyhill]

Thank you sooo much for that info.
I'm 56 and I've never heard anyone say that it won't hurt you..😇🖒

[rosstituteuk]

not all zinc is created equal. zinc in the diet is typically bound to proteins aka chelated. zinc fumes from welding are likely in the zinc oxide form, which I suspect is much less useful to the human body.

Am looking how to stick weld galv square tubes, but came to the wrong place.

[chrisp]

2:18 it might not be a carcinogen but it’ll still fuck with your lungs and how you’re breathing. Wear a N95 and you’ll be fine.

[alanmorrison]

We humans take Zinc pills but NOT Zinc oxide pills..From most all authoritative sources on this subject, Zinc oxide smoke should be avoided when welding. Otherwise in my view, your video is very informative!

[michaelengelthaler]

can you weld with 30 gauge sheet mettle

My favorite was a guy who was about to make a rack to lay meat on for his grill from galvanized material untill I asked if he was throwing a party to poison his guests? He was under the impression that it would burn away. I replied "Well then I guess your steaks will have an interesting spicy taste to them". Stupid can't be bought only born.
