How to weld with Galvanized Steel

In this informative video, we delve into the chemistry of galvanized steel and the complex welding process it requires. Understand zinc's vital role as an anti-corrosive layer and how it's chemically bonded to mild steel for durability and strength.

Max takes a deep dive into the essential precautions when welding galvanized steel. The video demystifies the risks and safety measures needed to avoid zinc fumes and potential zinc poisoning, an essential consideration for all welders.

We then take you step-by-step through preparing and welding galvanized plates, discussing the importance of cleaning both sides of the material, and even providing a handy tip about identifying mild steel by the colour of the spark!
See the consequences of welding dirty galvanized plates in real-time, as Max welds without any prior cleaning, leading to many issues, such as unwanted porosity and the formation of white residue - evidence of remaining zinc.

This video also showcases how proper preparation and removal of the zinc layer can result in cleaner, safer welds, highlighting the stark difference in the final result.

Remember, even with proper preparation, safety should always be paramount. Max emphasizes the importance of employing protective gear, like respirators and fresh air units.
Finally, we address post-welding considerations, such as the need for additional protective layers to prevent oxidation and corrosion, given that the galvanized layer is compromised during welding.

Very helpful. Learned a few things. Music is distracting, though.

Very useful content, but the background music is not necessary.

Does anybody make welding wire or rods that can weld over the galvanized coating?
