A heavy coated basic type, hydrogen - controlled, electrode which deposits weld metal having about 0.60% nickel and is of radiographic quality. The deposited weld 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.
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.
REDRYING TEMPERATURE :250° C/ 2hrs
DIFFUSIBLE HYDROGEN :max 5.0ml/100g of weld metal in the weld metal
