HellO,
I have not found for the certification process, how weld in 3G position, I mean, upwards progression or downwards progression, or doesn't it matter.
Also, I have a great doubt, I don't know if it is stupid, but I have to ask because I have not found anything.
Does any welding position apply to weld any material (I will use the groove weld test, 3G)? I will certifie the follows materials:
-Inconel 718, t=0.071"
-Ti 6AL-4V, t1=0.063", t2=0.071"
-Aluminum 6061, t1=0.063", t2=0.071"
-Stainless: 17-7PH, t1=0.063", t2=0.071"
