I used to do a lot of heavy cast iron brazing with 1/4 low fuming bronze rod. When you get sick, it feels like the flu. A doctor at the time told me that the zinc will disapate from your body, and should not cause long term problems. I later started wearing a respirator. If you are welding thin zinc plating such as electrical conduit, tig it with silicon bronze. You will love it. It is strong with a good appearance and you won't lose as much of the protection of the plating.😊
@@aswervio7852 am now welding a greenhouse from 50x50 mm 1.5 and 1.2 mm galvanized square tubing . Nothing so far but i got issues welding it with a stick as it doesn't stick well sometimes and if i push harder or up the Amperage i make a hole . Damn awful! İ go slow dub dub first pass then full weld zigzag but mostly need third to fill in cold welds as it doesn't stick well.
You’re 100% correct and I’ve told many of my helpers (when I’ve rarely had one), “ if you ain’t seeing sparks, you’re not done yet”. I typically find that welding it with hard wire and 75/25 works pretty good but you need to turn your gas up and use a push travel ONLY! This way when the arc burns through it, your gas can blow it away before the puddle gets there.
Great info Chris, when the video popped up I'm like don't breath it, hold your breath!! Respirator for sure. And Neil, I'll have to try the wd40 on the wheel as that solvent works for a lot of things.
Trying very hard to learn how to weld properly when I was young which was very many years ago in the farming Community where I was raised the farmers were given the option to keep high-tension high-voltage towers that were taken down to re be replaced with bigger ones I cut a lot of that metal up for one of the farmers and like you said you will get super sick and feel like you're going to die so please be careful if you're cutting it burning it in any way shape or form welding with it if you do anything to it that makes it turn red wear masks or do it outside and well phenolate area
My dad worked vessel shops for years. Never wore respirator. But he would drink at least a gallon of whole milk a day. His doc told him milk helps remove the zink from your body.
You realize the vaccums filter doesn’t have the chemicals inside it to turn the zinc smoke back into a solid right? Yano the whole thing those 3500$ respirators do ? Your essentially sucking it into a very poor ( virtually ineffective ) filter and then blowing it maybe 5-10 feet away from you since shop vacs blow exhaust backwards.
Thanks! I'm gonna try that because I need to weld a frame from galvanised 1" box section. Here in the Philippines I can only lay my hands on galvanised or stainless, and stainless is well expensive here.
My buddy Darrell got heavy metal poisoning from welding so much he did it from the time he got back from Vietnam to a few years ago now he gets treatments weekly and can’t hardly walk from it all no shame in a little ppe especially when you are messing with galvanized we didn’t really know better back in the day but the cats out so take a few precautions and let the sparks roll off the starch
The zinc coating which is galvanisation is what gets you sick, if you weld and burn it, it will be in the air, and if you grind it, it'll also be in small fragments in the air but probably not as bad. You can remove zinc with certain acids and other treatments without causing fragments or aerosol, or you can just wear an aerosol/particle mask.
Be super careful cutting it with a plasma cutter, it vaporizes so much of it so fast you just about have to run away from the cloud......ask me how I know
@@TaylorWelding An operator came over to the maintenance shop with a piece of dust collection ducting that was thin galvanized sheet metal and asked me to trim some off, knowing the plasma would slice right through it I said sure. Marked it out and cut it in about 20 seconds before I knew what had happened I was standing in a yellow cloud.......I took off out of the shop and around the outside to open a bay door.
Another YT welder suggested using muriatic acid 1:1 ratio with water. It works. Completely dissolves the galvanize away. However, the challenge is submerging the welded parts. It only takes a few minutes (3-5). I am replacing my gutters with 18 ga galvanize. Sheetmetal shop just did the bends and cut the end pieces for me. I dipped the ends of the gutters in about 1/2" of the acid and water. It looked like a bathtub ring where the galvanize was removed. I submerged the end pieces also. No grinding. The other thing too, when done welding, you need to paint it. It can flash rust fairly quickly.
Just be aware that this produces hydrogen gas so not for confined spaces, also steels with a tensile strength >150ksi can absorb hydrogen if stripped or pickled in an acid bath leading to embrittlement
I welded a trunk floor in a car once with a white N90 particle mask, It was almost black within 10 minutes and I was SICK! Do as this man says. Find a respirator to fit under your helmet. You will thank yourself down the road.
Well known that you do not weld galvanized. Fumes will cause metal fume fever. Grind off the galvanized coating before welding. Same for Chromium plated or dipped metal. I would be wearing a powered air supply respirator.
In the tropics we get a lot of galvanized welding jobs. Tough stuff. But anytime you weld, whatever was on that material either from the manufacturing process or from whatever Farmer John sprayed on it to make it last forever, it's a toxic soup best to be avoided with some good respiratory protection. Loved this episode. I really learned some things I can apply tomorrow!
I wish I'd seen this last week. I had my first experience with galvanized last week at work, and it's absolutely miserable to weld. I figured out some things that worked, and produced barely acceptable results (by my standards - the other guys working on it had much worse looking welds, which the company also considered acceptable), but I knew there's got to be better ways.
This video came at a great time Chris. Working with some galvanized on a muffler repair for a customer. Literally hate galvanized and the smoke that comes with it. Using Fluxcore E71T-11 21B Fabshield on the mig welder to weld the muffler.
Gonna share a trick my welding instructor taught me years ago. Douse that galvanized in white vinegar, it’ll knock down that nasty poison cloud that cooks up off when you’re welding. Try it and see what you think. Thanks for all the videos brother!
Awesome video iv used the tortch at times to try to burn it off when I couldn't get a grinder in a tight spot does work but definitely stay out of the smoke
My pal got the green smoke in him once. I know from his experience that it is to be avoided. I also know another guy who almost killed himself by inadvertently making a nerve gas while TIG welding--something to do with residual brake cleaner in an unseen pit, which with heat and Argon turned into some super deadly stuff. He was hospitalized for a few days and took months to recover. He wrote about it way back. Had he not used brake clean, or been on smooth metal, or used a different shielding gas--nothing would have happened. He said he saw the tiny puff of smoke when the chemical in the pit combined with the Ar. His suffering started soon thereafter. The event is still descrbed on his site if you want to look it up. He is Steve Garn at Brew Bikes. I'd give a link but you know the AI will delete it-so I quit trying to share links.
What’s the best way to get a job stick welding. I work in a shop welding mig but eventually I want to do stick and tig and want to know the best way to get into it. Thanks love the videos keep it up
Get a big box of 6010 or 7018 and burn a fat fist full every night after work. Be super picky about making each weld perfect. Or community college if you have the opportunity.
Get a single tig rod and tig glove. Left hand if you are right hand. Watch a movie and inchworm that rod through your left fingers until it's first nature.
I would go anywhere that stick welding was going on and talk to them. I would also look for shut downs or a.k.a. turn around and see if I can get a job as a structural welder, and eventually move into pipe.
I was stick welding galvanized last week to shipping container wall steel. Problem is controlling the pool. Overheadhorizontal is hard on the shoulders and fairly difficult. With lower amperage and good filler control, beautiful welds with gorgeous penetration are only a millisecond away from holey sheet or holy pass. I like your videos so far. Keep up the positive content man!
When I was young worked for a dairy supply dealer. We were sent to install and weld with arc/stick galvanized herringbone stantions in a parlor. I would weld one weld and go outside and puke for a bit while my partner did his weld and we both were very sick the entire time. I wish we had been warned.
Hey man thanks for all the advice. Could you please link that video for welding through paint with 7018 please I can't seem to find it. I started working for a small ironworking outfit just under 3 months ago straight out of community college classes and the biggest change I've had to learn is how to weld through galvanized and paint on material. We're welding through galvanized and paint all with straight 7018 it's definitely made me have to incorporate different techniques to my welding but I'm starting to get the hang of it.
definately have a fan and preferably respirator but if u start getting the neck ache and stomach cramps all you can do is drink milk in my experience. i get sick almost everytime i mess with it drom carlessness
I've had a job welding this stuff in an apartment building for the last 2 weeks I'll tell you the first day I didn't wear a mask my teeth hurt 2 days later and I felt like it was poisoned pretty damn stupid. I've heard that there's discs for grinding aluminum and they work better and don't get contaminated.
I've heard that several times through life and multiple times in the comments. All I know is you can't drink milk all day long when it's 100 degrees outside. I'm gonna say just stay away from it. or use a Respirator
lets say your working an project and have alot of galvanied tubes and you,grind,weld them(with mask ofc and outside) and in condition were there is alot of humidity when its built . what would use to cover the welds? (beside zinc paint spray which only last some months) ? the same paint primer the use to paint ships with?
Try not to breath. One of the guys told that to boss. The hood will usually keep the stuff away from your face but be aware that it not only falls but floats upward. Protect yourself best you can people. Meet a welder that looks younger than his age.
When we were welding galvanized posts in the army, we were told we could weld for a half hour, then drink a quart of milk wait an hour then cycle of over
@@TaylorWelding PAPR systems are battery powered forced filtered air respirator systems built into an enclosed welding hood. they seem to run 1-2k$. you dont have to wear the facemask for smoke filtration. ARCone welding works in the UK and they are kinda mandatory over there. Powered Air Prefiltered Respirator?
If welders are in the practice of fabrication, why are there 50 tutorials about making your own papr? I've never gotten zinc sick because I won't weld zinc. People I know say they been zinc sick so many times.
I learnt after I breathed a little bit ..outside in a wind...yep...I got a lung fulll and although I didnt have breathing issues it took all my energy and gave me a headache like you cant imagine ...just don't breath it..and be really careful if you forge and try burning it off metal. It will get you at some point. Thanks for sharing , those are some pretty neat, tidy welds considering what you were working with
I run flux core & tend to ignore whether the steel is galvanised or not. Flux core barely cares. "Crud" floats up in the flux - zinc counts as crud in this case.
I agree with you sometimes we can grind it sometimes we can't but we can't listen to the armchair welders all the time if you'd hear some of the dumbass things some people say they do when welding galvanized steel you'd roll over laughing
