Griduct 96P2, E 9016-G
AWS/SFA 5.5: E9016–G
A basic type hydrogen controlled electrode specially designed for welding of high strength steels type WB-36 or equivalent. Striking and re-striking properties are good with little spatter and easy to remove slag. Deposited weld metal is tough, crack free and is of radiographic quality. The low hydrogen nature of the flux coating makes the electrode especially suited for joining crack–sensitive high strength pipes.
