OK 48.00 SMAW Type Basic
A reliable, general purpose, LMA electrode for mild and low-alloy steels. OK 48.00 deposits a tough, crack-resistant weld metal. High welding speed in the vertical-up position. OK 48.00 is insensitive to the composition of the base material within rather wide limits. The electrode can be used for welding structures where difficult stress conditions cannot be avoided. Welding current, A DC+(-)
