May I ask where the problem of unqualified mechanical properties in this welding procedure qualification might lie?

1. A dual pulse should result in a pulse arc transition； 2. Manganese-rich welding wires are suitable for protective gases with a higher oxidizing capacity, such as pure CO2; if the gas is not changed, manganese-medium welding wires should be used ； 3. It states that the mechanical properties are unqualified, but it doesn’t clarify whether it’s a failure in bending or in impact resistance
