Welding Position

Characteristics
ER2209 provides a ferritic-austenitic weldament that combines many of the good properties of both ferritic and austenitic stainless steels.

Procedures
Welding without filler metal(i.e. TIG dressing) is not allowed since the ferrite content will increase drastically and both mechanical and corrosion properties will be negatively affected. Ar (99.95%). Ar with addition of up to 2% nitrogen (N2) is advantageous and will have a positive affecton both mechanical and corrosion properties. Gas flow rate 4-8 l/min.
