Low Hydrogen Electrodes - Premier 7018-1

Characteristics :
PREMIER 7018-1 is a heavy coated, all position, low hydrogen type electrode which gives extremely smooth arc, medium penetration, least spatter with an easily removable slag. Deposition efficiency is about 115%. Electrode is specially designed for high impact values at sub-zero temperatures. It can also be used on mild steel applications where the structures have to withstand sub-zero temperatures. It is recommended to use minimum possible heat input while welding.

Applications :
Structural steels, Low alloy steels, Low temperature steels, High carbon steels, Rails, Wagons, Bridges, Boilers, Pressure vessels, Tanks, Ship-building, Cranes, Machine building, for joining seals, speed rings and spiral casings of turbines, joining alloy steels such as Si-Mn, heat treated steels containing Ni upto 1.0%. For heavy joints under restraint and subject to dynamic loading.
