welders ? on galvanized

Is there a way to make galvanized metal safe to weld? I have some galvanized tube that is just the right size for what I need and would save me a ton if I can make the galvanized safe to weld. If not how dangerous wouldd it be to make brief welds if done outside on a breezy day

P.S. The monkey really freaks DennyF out

You can weld it just like any other steel. I would wear a respirator just to be safe and save your lungs from the zinc oxide. Depending on your weld method you may need to adjust the voltage on the MIG. You will also need fluxcore.

I think this article has all the info you would need. http://www.nakedwhiz.com/weldinggalvanized.pdf

I'm very important. I have many leather-bound books and my apartment smells of rich mahogany.

Ventilation is the key. In this case, ventilation is as important as having clean surfaces for welding.

Depending on your process - MIG bare wire or flux - or stick - avoid the fumes from welding. Then avoid breathing in the "soot" produced.

Galvanized welds like any other steel except that the zinc is an impurity and burns off. There is some lead in the mix, but modern coatings has much less. Hot dip Galv is another thing entirely - but can still be welded.


Getting a lung full of the smoke isn't an automatic death sentence - Def not good - but isn't going to put you down. Take reasonable precautions with your project. Avoid the fumes and the soot in the weld area.

Is your position a short term gain - or a long term loss? Separate the issues.

Make sure you have a lot of ventilation, if your skin starts turning red and you feel sick, you most likely poisoned yourself.
