Avesta 2205 description: AVESTA 2205 is primarily designed for welding the duplex grade Outokumpu 2205 and similar but it can also be used for 2304 type of steels. AVESTA 2205 provides a ferritic-austenitic weldment that combines many of the good properties of both ferritic and austenitic stainless steels. The welding can be performed using short, spray or pulsed arc. Welding using pulsed arc provides good results in both horizontal and vertical-up positions. The best flexibility is achieved by using pulsed arc and 1.20 mm wire.
