Development of stainless steel welding wire for galvanized steel sheets.

Stainless steel and galvanized materials often are found together in the industry with applications such as galvanized fasteners stainless steel pressure vessels and roof and siding panels. Galvanneal is the process of taking hot dipped galvanized steel and passing it through a furnace to anneal the coating. When galvanized sheets are welded zinc near a weld molten pool evaporates. As a result the corrosion resistance is deteriorated and repair coating treatment is required after welding.

The use of austenitic stainless steel welding materials with suitable ductility and high corrosion resistance appears to be beneficial. This process causes the iron and zinc layers to diffuse into one another causing the formation of zinc iron alloy layers at the surface. The presence of two dissimilar metals in an assembly is not always a sign of trouble but it could be a problem. Welding of stainless steels 1 0 introduction stainless steels are defined as iron base alloys which contain at least 10 5 chromium.

Similar to galvanized steel is galvanneal steel. For galvanized steel plates with a strength level above 500mpa e5001 e5003 welding rods should be used. There are five types of stainless steels depending on the other.
