Hi there, all,

I'm a bit confused - I thought welding galvanised steel was a No-No!?!?  Please explain? 

John Rudd:
Galvy can be welded...just grind off the coating, use plenty ventilation avoid breathing the fumes...

awemawson:
It's the fumes that cause problems to the welder - if you get 'galv poisoning' your head starts to spin and you feel dizzy. Drink lots of milk asap.

The zinc will interfere with the integrity of the weld, so don't weld galvanised sheet for use in nuclear pressure vessels  :zap: But for every day run of the mill stuff it's not a major issue.

The galvanising can be removed physically with a grinder etc., or chemically with an acid.

Hi Pete , I have never had a problem with welding Galvanized sheet steel ,been welding it for years ,  safe as houses , yerh if you're a complete tit and breathe the fumes then you get what you deserve . As with any welding/brazing/soldering  operation the fumes are bad for you . , Over on Idiots forge iron it's a different story , it's instant death if you do .,,,,,,,,,,,,,and the sky will fall in lol .

AdeV:
All the metal I've been welding into my Jaaaag is galv, just because I happen to have a "few dozen" square feet of it that I scored a while back. It's hard to tell if the Zinc fumes are affecting me as I was already  :loco: mad before I began the project!  :lol:
