Gee Limited

Identification :

GRIDUCT - 5 E 7018G

Classification :

AWS/SFA 5.5 :  E 7018G,   IS814 : EB5626H3 JX

Characteristics :

A heavy coated basic type, hydrogen - controlled, iron powder electrode with high deposition efficiency. The electrode deposits weld metal having about 0.60% nickel and is of radiographic quality and meets impact requirements at minus 50° C.

The weld deposit is tough, ductile and is highly resistant to hot or cold cracking even when subjected to high stresses, dynamic loading etc.

Typical Application :

For the welding of structural steel where resistance to brittle fracture is required under adverse operating conditions such as those found in off-shore production platforms.  Used for production of pressure vessels, bridges,pipelines Recommended for higher carbon & higher Sulphur steels, which are susceptible to hydrogen induced cracking.  For welding SAILMA 350HI steel, storage tanks, pipe line etc.
