Development Of Stainless Steel Welding Wire For Galvanized Steel Sheets

The use of austenitic stainless steel welding materials with suitable ductility and high corrosion resistance appears to be beneficial.

Development of stainless steel welding wire for galvanized steel sheets.

Development of stainless steel welding wire for galvanized steel sheets article in welding in the world le soudage dans le monde 54 1 2 january 2013 with 6 reads how we measure reads. There are five types of stainless steels depending on the other. When galvanized sheets are welded zinc near a weld molten pool evaporates. Welding of stainless steels 1 0 introduction stainless steels are defined as iron base alloys which contain at least 10 5 chromium.

As a result the corrosion resistance is deteriorated and repair coating treatment is required after welding. The presence of two dissimilar metals in an assembly is not always a sign of trouble but it could be a problem. For mild steel galvanized steel sheet j421 j422 or j423 welding rods should be preferred. For galvanized steel plates with a strength of over 600mpa the welding rods of e6013 e5503 and e5513 should be selected.

The thin but dense chromium oxide film which forms on the surface of a stainless steel provides corrosion resistance and prevents further oxidation. Galvanneal is the process of taking hot dipped galvanized steel and passing it through a furnace to anneal the coating. This process causes the iron and zinc layers to diffuse into one another causing the formation of zinc iron alloy layers at the surface.
