Gentlemen,
I am trying to weld FH36 with flux core K81-T (Kiswel with 1% Ni) and test it at -60 degree C, 34J but it is always fail (20 J).
The setting is:
Setting 1: current 240 (A), Voltage 24 (V), interpass temperature: max 60 degree C.
Setting 2: current 220 (A), Voltage 24 (V), interpass temperature: max 60 degree C.
The result for both setting are same (20J).
Could anyone tell me how to improve this impact value?
Thanks very much,
Trung
