ATOM ARC 8018

Atom Arc 8018 electrodes deposit 1% Ni weld metal. It is used primarily to weld high-tensile steels, especially where notch toughness at low temperatures is required.

Features

Atom Arc 8018 electrodes deposit 1% Ni weld metal. They are used primarily to weld high-tensile steels in the 70-80 ksi (483-552 MPa) tensile strength range, especially where notch toughness at temperatures as low as -40°F (-40°C) is required.

Extra Info

Preheat should be used on hardenable steels to prevent the formation of a hard heat-affected zone. Preheat may also be required in welding heavy sections
