ATOM ARC 7018-1

Atom Arc 7018-1 is an all-position low hydrogen iron powder electrode that displays exceptional impacts at low temperatures in both the as-welded and stress-relieved conditions. Smooth metal transfer keeps spatter to a minimum, and the complete slag coverage is designed for easy removal.

Features

Atom Arc 7018-1 is an all-position, low hydrogen electrode that provides exceptional impact toughness at low service temperatures. Atom Arc 7018-1 provides smooth metal transfer, minimal spatter, and easy slag removal. Atom Arc 7018-1 is used to join a wide variety of carbon and low alloy steels. It is also an excellent choice for welding higher strength steels if undermatching welds are specified.

Extra Info

Preheat is generally not required with Atom Arc 7018-1 to prevent underbead cracking. Preheat should be used with hardenable steels to prevent the formation of hard heat-affected zones and eliminate tendencies toward quench cracking on cooling. Preheat may also be required in welding heavy sections.
