OK 48.15
SMAW
Type Basic
An LMA electrode for welding mild and low-alloy steels. Unusually good welding properties in the vertical-up position. OK 48.15 gives the same good weld metal quality as OK 48.00, which makes the electrode suitable for welding structures in which high stresses cannot be avoided. It is also suitable for welding galvanized plate.
