Avesta 2205 description: AVESTA 2205 is a Cr-Ni-Mo alloyed duplex electrode for welding duplex steels such as 2205. For light to moderate thickness material, welding should be carried out as for ordinary austenitic stainless steel. However, the somewhat lower penetration and fluidity of the weld should be considered. Very high quench rates and excessive times at red heat or above should be avoided to prevent excessive ferrite or formation of intermetallic phases.
