Weldability

Weldability refers to the ability of a material to form a permanent bond with the same or another material through welding processes. This property is significantly influenced by factors such as chemical composition, thermal conductivity and oxidation behaviour. Stainless steel containing at least 12 to 14% chromium is characterised by high weldability. The chromium content enables the formation of a passive chromium oxide layer that protects the material from corrosion. When welding stainless steel, it is important to use suitable shielding gases such as argon or helium to prevent oxidation and ensure the quality of the weld seam. Thermal conductivity should also be taken into account, as it influences the choice of welding parameters. Overall, the weldability of stainless steel depends on carefully matching the welding technique to the specific material properties.
