E7018-A1

AWS A5.5 Class E7018-A1 (Weld deposit also meets the requirements of AWS A5.5 Class E7015-A1 and E7016-A1

USA 7018-A1 is an iron powder, low hydro-gen electrode designed for welding low alloy, high tensile steel of
65,000 psi minimum yield strength and containing 1/2% Mo. This electrode offers the welder high deposition efficiency and produces a weld deposit with fine bead appearance, easily removable slag, low spatter and medium penetration. USA 7018- A1 weld metal solidifies rather rapidly, making this electrode suitable for out of position welding.

Applications:

USA 7018-A1 is typically used for the fabrication of carbon-molybdenum pipes, pressure vessels, boilers and tubing containing 1/2% Mo.
