CLASSIFICATION：
GB ER50-G/ISO 14341-B-G11/ AWS ER70S-G/JIS YGW11
DESCRIPTION：
Compared with the ER70S-6, ER 70S-G welding current is greatly increased and the welding efficiency is improved.Because the grain of deposited metal is refined, its tensile strength and yield strength are all close to the upper limit of 500N/mm2 tensile strength grade, and the impact absorption work is obviously improved as well.
FEATURES：
High capability on oiled and oxide parent metal, low stometal sensitivities. Forming well, less welding spatter, Stable arcing, arcing 99% under low current welding with 0.8 wire. For base metal of 500N/mm2 tensile grade high speed welding.
