EIL at CPCL site Chennai and at BPCL site, Mumbai. Also by LRS, ABS, BV, DNV, IRS, BIS(ISI), CHIEF INSPECTOR OF BOILERS BHEL (Trichy).
Welders friendly heavy coated basic type, hydrogen - controlled, iron powder electrode with high deposition efficiency.
Weld able in all positions (F.H.V.O). Welding technique including arc striking/restricting calls for practical experience for best result. The bead appearance is smooth and the slag is compact, thick and easily detachable. Deposition efficiency of weld metal is approx.115%.The welds are of radiographic quality.
For radiographic quality welding of highly stressed crack sensitive Joints in steel structures, ship building, heavy duty boilers and pressure vessels, bridges, storage tanks, high pressure pipelines etc. Recommended for higher carbon & higher sulphur steels, which are susceptible to hydrogen induced cracking.
REDRYING TEMPERATURE : 250° C/ 2hrs
DIFFUSIBLE HYDROGEN : Max 4ml/100g of deposited weld metal.
