I like to ask if high Manganese on the welding wire could effect the weld finish and how.
I'm working with A572/65 materials Manganese max should be 1.35 but my welding wire manganese content is 1.6 - 2.1
I'm experiencing cracking at the toe of the welds at the heat effected zone.
I'm also using 90% Ar / 10% CO2 for shielding gas and the Tensil Strength is up to 106,500 PSI when I know that A572/65 Min-Max Tensil strength is 80,000-105,000 PSI
Should I change to a different filler metal?
Your response will be appreciated
Best regards,
