How to perform the welding of 2205 duplex stainless steel
Thread Content
Our unit has never used this material before, and we don’t know what welding material to use
2205 duplex stainless steel – first and foremost, it is a type of stainless steel. The welding material chosen is a stainless steel welding material, selected based on its microstructural composition, mechanical properties, corrosion resistance, and other characteristics. E309Mo-16 can be chosen as it offers good formability with acidic welding materials, while alkaline welding materials provide better mechanical properties. It depends on the requirements of your device. Just do it normally for the evaluation
ER2209 E2209-15
Well, E2209-15 has poor weldability; let’s use E2209-16 instead
