The issues associated with welders galvanized coating

Welding as we know is a process wherein two or more metal pieces are joined together with the help of a molten solution that forms the essential bond between them upon cooling. Though it seems as simple as that, practically there are lots of shortcomings involved that you need understand well, memorize them and put them for practice while welding.

Always remove galvanized coating from the welder before welding stainless steel, especially while welding any kind of galvanized metal pieces. However, this procedure of removing the galvanized coating depends upon what you are welding and how critical is the procedure or process implied to weld the materials. And this stands true irrespective of whether you are using a TIG welder or an MIG welder.

Galvanized coating is nothing but zinc cover upon the welder. A common problem that you are most likely to come across while welding along with this galvanized coating is that cracks develop on the surface of the material you are welding, especially if you are using a welder with a high silicone content wire common as in the case of MIG welders.

Always clean the coating while you are welding galvanized materials. Or else, the zinc coating will give rise to nauseating fumes that makes it difficult to breathe and focus on the process. On extreme cases, such as huge exposure to such fumes could even cause pneumonia. And this is not the case with only zinc coatings; it is also predominant with plasma spray, paints, chrome and many other similar materials.
