S-7024.F
COVERED ELECTRODES FOR CARBON STEELS
AWS A5.1 / ASME SFA5.1 E7024
JIS Z3211 D4324
l Applications
S-7024.F can be used for welding of flat and horizontal fillet welding of internal structures, inside hulls, building, machine construction.
l Characteristics on Usage
S-7024.F is a representative powder titania type electrode widely used for flat and horizontal fillet welding. this is an excellent electrode with extremely high efficiency.
l Notes on Usage
a) The optimum speed ratio is 1~1.5%.
b) Usability degrades when moistened. In case of absorbing moisture, it must be dried. [70~100℃ (158~212℉), 30~60minutes]
