I am having 3 approved WPSs for P91 material.These 3 WPS are using 3
different electrodes.
1)9018-B9 -Iron powder & Low hydrogen potassium coated
2)9016-B9 -Low hydrogen potassium flux coated
3)9015-B9 - Low hydrogen sodium flux coated
My doubts are
1)How we can justify which electrode is better for my use?
2)Any where in code it mentioned the suitable flux coating for
electrode?
