Applications
AWS A5.17 / ASME SFA5.17 F7A(P)6-EM12K Multi-layer welding of structural steels, offshore structures and thick, windmill, pressure vessels.
Notes on Usage
Characteristics on Usage
Good weldability for all range of thickness of plate. Excellent impact value and crack-resistibility of
welded metal. Inactive type flux is not affected by welding parameter, especially suitable for multilayer welding of thick plate.
① Dry the flux at 300~350°c (572~662°F ) for 60 minutes before use.
② For the first layer in groove, keep the current and speed low in the case of multi-layer welding.
