About Product :

In package : 2.2 kg

L : 350mm

It has a basic character cover. It is used at the source of large mass fixed steel structures, where strong welding stresses are inevitable, thanks to the high resistance of the welding metal to cracking.

Slag is easy to lift and high quality welding seams are obtained. It provides the ability to work with high welding speed in the bottom-up welding position. Its yield is 125.

Usage Areas and Materials Welded

Developed for the source of machinery and steel constructions operating under the influence of dynamic strain. Shipbuilding, pressure vessel, tank and boiler manufacturing, pipe connections are other application areas. Suitable for root passes and difficult welding positions, AS B-248 gives stitches with high notch impact resistance at operating temperatures below 0°C. It is also suitable for the source of GALVANIZED sheets.
