Welding Galvanized Steel Mig. There will be three melting points you will be dealing with. Due to its lower power needs this method could be used outside and offers a distinct advantage over MIG in this regard provided the dangers surrounding the zinc oxide by-product.
To weld a tear or split in galvanized steel start on any edge of the metal. When using MIG or flux cored welding one may have to adjust the voltage slightly to control spatter and one may have to clean the welding gun of spatter and zinc oxide deposits more frequently that when welding uncoated steel. MIG welding is one of the simplest to use for welding.
Steel on the other hand can vary a lot depending on the grade of steel being used it can move between 1425 to 1540 C.
The point is I know that you have to remove the Galvanizing if you want to weld any sort of galvanized steel But do you have to remove the plating if you want to weld Zinc plated steel. It is an arc welding process that where you feed a solid wire electrode through a welding gun. When using SMAW stick welding galvanized steel can be welded in the same manner as uncoated steel. There are a few interesting things to note here.
