I need to weld some nuts to a steel tube. Are there any issues with using regular zinc coated nuts or are there other, plain steel nuts I should be using?

Zinc fumes are toxic so you should clean or grind it off before welding
I do this a lot at work. It’s not easy to weld galved steel, so either grind/sand off the zinc on the nut (not the easiest to do if they’re small!) or use a plain steel nut. If the tube is galved, sand the galv off that too around the area of the weld.
The fumes from zinc are toxic so wear a mask and weld in a well ventilated area.
