Materials
Can you stick welding galvanised steel?
Quick answer
Yes — good tolerance, more fume. Stick on galvanised steel: match technique to the material; filler same as mild steel; silicon-rich wires handle zinc slightly better.
The verdict and why
Good tolerance, more fume. Zinc fume causes metal fume fever ('welders' flu') — ventilation or a fresh-air mask is non-negotiable under AS 1674
Watch-outs
- grind the gal off the weld zone where you can — it's faster than fighting porosity
