SM-80G
SOLID WIRE
AWS A5.28 / ASME SFA5.28 ER80S-G
JIS Z3312 YGW21
l Applications
Butt and fillet welding of steel structures and using 550N/mm2 or 600N/mm2 tensile steels such as construction machinery, buildings and pressure vessels.
l Characteristics on Usage
SM-80G is a solid wire for flat and horizontal fillet welding position. As the deposition rate is very high, highly efficient welding can be performed. As the wire contains special elements, its bead appearance is excellent.
l Notes on Usage
a) Use welding grade CO2.
b) Flow quantity of shielding gas should be 25L /min. approximately.
c) Use wind screen against wind.
d) Keep distance between tip and base metal 6~15mm for less than 250A, and 15~25mm for more than 250A of welding current.
