One common approach to reduce porosity is by reducing the welding speed which leads to a lower productivity. Safety Concern In addition to the weld-related issues stated above porosity cracks lack of fusion and spatter there is a higher than. 2 7 CO2 Spot Welding 30 Section 6 Shielded Metal-Arc Welding 33 General 33 Galvanized Steel 34 Metallized Steel 46 Zinc-rich Painted Steel 47 Section 7 Automatic Welding.

This results from the variation in boiling points between zinc lower and steel.

Zinc coating thickness due to the generation of the zinc induced external and internal porosities in the weld deposit requiring rework time. This is a viable alternative but not the only way. Zinc will not produce sparks when grinding and it is hard to tell the zinc from the metal sometimes after grinding. When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area.
