AWS A5.1 / ASME SFA5.1 E7018
JIS Z3212 D5016
l Applications
S-7018.G can be used for highly efficient-welding of 7,300 lbs/in2(50kgf/mm2 ) class high tensile steel, such as bridges, buildings, rolling stock and machines.
l Characteristics on Usage
S-7018.G is an iron powder low hydrogen type electrode of high efficiency used for welding 7,300 lbs/in2(50kgf/mm2 ) class high tensile steel.
l Notes on Usage
a) Dry the electrodes at 350~400℃ (662~752℉) for 60 minutes before use.
b) Keep the arc as short as possible.
c) Use wind screen against strong wind.
