welding galvinised material

[davidjohnperry]

hey guys I didn't post this in the mig or arc forum as I'm not sure what process I will be using but I dont fancy having galvanised flue again how is the best way to do this as i may have two or three small jobs to do I may be able to borrow my adflo from work if need be last time i did this I was un aware of the health risks it most probably be mig but as I'm unsure where it will be done ones a cage for gas bottles and one is a sign that needs to rotate for a show man friend I'm only doing this to win potential more work thanks in advance dave

I've welded galvanised without ever having a problem but you could use a carbon filter mask if your welding mask alliows

Grind the galv off, wear an Adflo. Job done.

 

[davidjohnperry]

ok ill do that is one process better then the other I know the zinc causes issues with the weld process I don't fancy doing the job more then once

 

[Welderpaul]

Stick weld it if it isn't a lot of welding. Stick is a bit more forgiving than MIG if the metal isn't the cleanest.

Well I've welded galve quite a bit and never had any problem , most of the light steel box I buy here is galve it welds up loverly with my mig .. now and again I repair something that has been galve dipped , it does not weld too badly if you flap disc it gently ... as for the so called galve flue thing I've never had any after fx from welding galvanised steel....jeff...

It is always worth the extra time grinding the galvanise back, even if you can get away with burning back with mma. Watch the metal colours to tell you when you're down to steel, some dipped stuff can be crazy thick.

But there are always bits in corners or inside box section that can't be removed.

If you have to do it indoors, try to get some through flow of air in the shop. Wait until you have a windy day if it helps pull air through your workspace. Or outside, especially if doing it with arc.

Rigging up some local extraction will help masses indoors.

If indoors, I use, doors open, extraction and mask. Outdoors, I'd try to get the best side of the wind and use a mask as backup. It's horrible stuff.

like I said I'm unsure where the work will be yet and I can borrow the 3m adflo system from work most probs like I said I only had it once and never put much thought about it till much later on and I kinda wanna try to avoid it if possible or minimise the risk as possible. I've got flap disks and grinding wheels so ill clean it to as best I can ill try and get some carbon filters for my 3m half mask for the grinding

 

[davidjohnperry]

unless some one knows of a better mask

 

[Mr shiney]

I use a 3M mask that fits nicely under my welding mask. I will see if I can find the part number.

I've lekky welded scaffy tubes up no bother and there heavily coated . it soon burns off . just take big breaths and get on with it

 

[ronan]

I was tricked into welding galv steel as an apprentice, never again, felt crap after it and the stink off it was horrible. Never again.

 

[davidjohnperry]

this is the half mask I use when welding

 

[outofthefire]

I have to weld it regularly, dipped is the worst but its the spitting that gets me more than fume fever usually. Its a big space with plenty of ventilation grind as much off as you can and go for it.

 

[davidjohnperry]

the little job for dad looks diped so might borrow the adflo from work

 

[outofthefire]

If it's a well ventilated place i'd just weld it (grind it off first) I get burnt far more than I get sick, but if it's a small space like a garage either do it outside or in the doorway and use the airfed if you can. If you've got any antispatter use that and tip dip as well.

 

[davidjohnperry]

I can grab some bits from work maybe it will be outside most probs the cage i might just stick weld but the sign that I might be involved with might have to be mig so ill take all this in to consideration thanks to all ill post some photos when i get sorted

 

[Welderpaul]

You know how to do it, just crack on with it mate. The best way to learn is to have a go rather than everyone debating the finer points of everything to the far end of a fart.

[davidjohnperry]

I fully agree @Welderpaul I just wanted some safety advice think I got it plus a few tips ill probably do the cage Friday afternoon photos will probs follow and thanks to all who replyed with advice and ideals
