Re: welders ? on galvanized
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.
