ESAB Atom Arc 7018-1 Electrode - 3/32" X 14" - 50 lb HS - 255013344
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.
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.
