ES SG3 is a bare Mn-Si-alloyed G4Si1/ER70S-6 solid wire for the GMAW of non-alloyed steels, as used in general construction, automotive components, pressure vessel fabrica tion and shipbuilding.
It has a slightly higher manganese and silicon content than ES SG2 to increase the weld metal strength.
This also promotes a low sensitivity to surface impurities and contributes to smooth, sound welds.
ES SG3 taking MAG welding operations to new levels of performance and all-round efficiency, especially in robotic and mechanised welding.
Characteristic features include excellent start properties; trouble-free feeding at high wire speeds and lengthy feed distances; a very stable arc at high welding currents; extremely low levels of spatter; low fume emission; reduced contact tip wear and improved protection against corro- sion of the wire.
