Low Alloy Electrodes


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.


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.


70181 is an all-position, low hydrogen electrode that provides exceptional impact toughness at low service temperatures. 70181 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.


8018C1 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 electrodes are used for attachment welds on T-1, HY-80 and HY-90 steels and other high tensile, quenched and tempered steels.
