Low-alloyed Electrodes
ES 9010 G A5.5: E 9010-G / EN 499: E 50 3 1 Ni C25
Description
It is an easy to strike cellulose coated electrode that provide the highest impact notch toughness values among our range of cellulose coated electrodes. Due to its higher mechanical properties, it is useful for the root and deposit pass of large diameter pipe connections having high yield strength. In all positions especially for vertical down position, it enables notch-free, smooth weld beads of high penetration. Especially recommended for hot passes, filler and cap layers. Highly economical compared with vertical up welding. It enables excellent molten pool control due to easily-removable, low - volume slag.

Applications
It can be used in the site welding of pipe and pipelines made particularly from low alloyed high strength steels. Site welding of pipe steels in the 5LX60 - 5LX70 range is a good example to application areas. It is an ideal electrode for welding in vertical downwards position. It generally used pipe materials welding.
