Welding Galvanized Steel Outside. The steel component is first chemically cleaned and then dipped into the molten zinc which is at a temperature of about 450C. Any outdoor project can benefit from the galvanization process if steel is involved.
It is an arc welding process that where you feed a solid wire electrode through a welding gun. Do not re-circulate the air in the shop. Proper precaution is needed when handling these coated metals as their fumes can lead to serious conditions like the Metal Fume Fever.
Continuous exposure to this smoke can result in galvanize poisoning.
The zinc volatilizes and leaves the base metal adjacent to the weld. Proper precaution is needed when handling these coated metals as their fumes can lead to serious conditions like the Metal Fume Fever. This results from the variation in boiling points between zinc lower and steel. 1 I know that galvanized looks like a rough grey finish where zinc-plated is a smooth shiny silver finish.
