It shields the work materials from the outside atmosphere. The flux is intended to improve the accuracy and quality of your welds. Shielded metal arc welding (SMAW) involves using a filler rod containing flux. Stick welding is preferred when you need to weld overhead or outdoors, as you don’t need to use a separate shielding gas. You hold a filler rod, similar to using an oxy-acetylene torch to weld. TIG welding is used when you require greater precision or need to fuse thin sheets of galvanized metal. MIG welding is the preferred welding method when working on large pieces of galvanized steel or when you don’t need to worry about making precise, clean lines. The wire is continuously fed through the welding gun. MIG welding involves the use of a filler wire that doubles as the electrode. Arc welders can reach temperatures of 10,000 degrees Fahrenheit.Ĭommon arc welding methods include MIG, TIG, and stick welding. The shielding gases help create a barrier between the galvanized metal and the surrounding atmosphere.Īn oxy-acetylene torch produces a maximum temperature of 6,300 degrees Fahrenheit at the hottest point in the flame. Potential options include:Īrc welding is preferred due to its higher temperature and shielding gases.
Types of Welding Suitable for Galvanized MetalĪfter removing the zinc coating, you can use a wide range of welding methods to weld galvanized steel. It also increases the risk of exposure to zinc and lead oxide fumes. The zinc coating limits the weldability of the material. The metal is dipped in molten zinc at a temperature of about 842 degrees Fahrenheit. It’s typically added using a hot-dipping process. The zinc coating protects the underlying metal from exposure to acid rain and moisture. Galvanized pipe is a common choice for situations where metal is exposed to moisture, such as: It’s made from zinc and helps prevent rust. Galvanizing is a process used to apply a protective coating to iron or steel. You can weld galvanized metal using the same process used for welding ungalvanized materials.
