Low Alloy Electrodes
7016
7016 is a low hydrogen, all position electrode used for welding heavy duty steel structures and plates. This electrode provides excellent arc stability and produces X-ray quality weld deposits with higher crack resistance, elongation and ductility than other mild steel electrodes.
7018
The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen and usually DC current.
7018-1
7018–1 is an all-position, low hydrogen electrode that provides exceptional impact toughness at low service temperatures. 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.
8018-C1
8018–C1 electrodes deposit weld metal which contains nominal 2.33% Ni. Their principal use is in the welding of nickel-bearing steels for applications where toughness of the weld metal at low temperatures is important.
9018-B3
9018 electrodes are used for attachment welds on T-1, HY-80 and HY-90 steels and other high tensile, quenched and tempered steels.
