electrode OK48 d. 2,5mm.

DESCRIPTION
A reliable, general purpose electrode for manual metal arc welding of carbon steels, carbon manganese steels and fine-grained carbon manganese steels with elevated yield strength. OK 48.00 deposits a tough, crack-resistant weld metal. The coating is of the low moisture absorption type. High welding speed in the vertical-up position. OK 48.00 is insensitive to the composition of the base material within fairly wide limits. The electrode can be used for welding structures where difficult stress conditions cannot be avoided.

REQUIREMENTS INCLUDING:

• Reliable, low hydrogen electrodes for general applications For mild and low-alloy steels. 

They deposit a consistently tough, crack-resistant weld metal and achieve high welding speed. These electrodes are relatively insensitive to the base material composition. A general electrode performing well on a wide number of base materials, perfect for welding structures where high stress conditions cannot be avoided.

• Low hydrogen electrodes for welding at AC/DC current. 

Increases the flexibility of using all types of welding equipment. Welding high recovery electrodes in AC current increases the deposit, delivers an excellent-quality weld metal with very good mechanical properties and self-released slag.

• Exceptional, all-position electrodes. For critical applications requiring special impacts at low temperatures. 

They provide a smooth, stable arc with very low spatter. Excellent arc starting is enhanced by a special graphite tip on the electrode. Complete slag coverage provides easy removal and minimal post weld clean-up, improving productivity. Intended for a wide variety of carbon, low alloy, and hardenable steels.
