Welding duplex / superduplex stainless steel to carbon ...Duplex and superduplex stainless steels may be welded to carbon steels using one of a range of consumable types. When selecting the most appropriate consumable, the need to have weld metal strength overmatching with respect to the lower strength of the two parent steels should be considered. The highest weld metal strength probably will be achieved with the use of a superduplex consumable.
Welding-duplex stainless steel is made easier by the current commercial grades that are low in carbon (less than 0.03 %C). These are free from the risk of sensitization and of intergranular corrosion due to carbide precipitation. Solidification hot cracking risk is reduced by the adequate presence of ferrite.Welding technology and application of 2205 duplex welding duplex superduplex stainless steel to carbonThe biggest characteristic of duplex stainless steel welding is the influence of welding thermal cycle on the microstructure of joint. Therefore, multi-layer and multi pass welding is beneficial, and the subsequent weld bead has heat treatment effect on the front weld bead, which can significantly improve the microstructure and properties of the whole welded joint.Welding parameters for duplex stainless steelsalloyed duplex stainless steel weld llers are suitable for welding the lower alloyed duplex stainless steel products.
