Hi all,
According ASME section IX, in case of welders Qualification of GMAW process - short circuit transfer mode, Radiography is not applicable and we must do Mechanical tests.
Need just to know what's exactly Short circuit transfert mode and how it can defferenciate of others ! by current range ?
Regards.
