is going to weld galvanized materials outdoors, was at Jula to buy a welding machine but a salesperson advised me against it due to extremely toxic gases during the welding of galvanized materials. Do you know about this? Isn't it enough to use a gas mask?
Welding galvanized steel produces particles of zinc oxide. The consequence can be that you suffer from so-called zinc chills, or metal fume fever as it is also called. Not the most pleasant, according to those who have experienced it. Milder forms of galv chills are managed by drinking a lot of milk, but as mentioned, it's nothing to play with...
When welding galvanized steel, use a powered respirator with a particle filter.

Grind off the galv where you plan to grind because the surface treatment will be ruined if you weld on it. Keep in mind that the strength can also be affected if the surface treatment is not ground off.
It's true, as Konrad and P-plats say...
As a welder myself, those who have experienced "zinkfrossa" once should stay away from such welding methods afterward. Just being in the same room is enough for the symptoms to return...
If you're careful to grind off all the zinc coating, you avoid the biggest danger, but stay away from the thick white clouds that come...
Feel free to drink a good gulp of milk afterward anyway... One can never be too sure.

Agree. Welding galvanized material is not recommended. It will also only result in pores and welding defects. Grind away and clean before.
