What welding rod is used for welding corten steel?

Answer 1

COR-TEN can be welded both manually and mechanically, provided the general rules of welding practices are observed. A prerequisite for obtaining identical mechanical properties in the weld and in the base material is the application of suitable welding consumables and the choice of appropraite welding conditions. To consider are EN 10025-5 - Technical delivery conditions for structural steels with improved atmospheric corrosion resistance Recommendations for welding are also given in EN 1011 part 1 and part 2 - Welding, Recommendations for welding of metallic materials-. Lime basic electrodes, inert-gas welding wire, and wire/power combinations equivalent to the tensile strength of S355 are used as welding consumables For unprotected use care must be taken that the welded joint is also weather resistant. This is possible by using welding consumables matching the base material. If due to design or building specification stress relieving is required, it should be performed in the range temperature from about 530°C to 580°C.
