SM-70G
SOLID WIRE
AWS A5.18 / ASME SFA5.18 ER70S-G
JIS Z3312 YGW11
l Applications
Flat and horizontal fillet welding of construction machinery, structural steels, bridges, ships, vehicles, etc.
l Characteristics on Usage
SM-70G is a solid MIG wire for flat and horizontal fillet welding and is to be used in a high current welding with CO2 shielding gas. It benefits from a high deposition rate and excellent penetration.
As this wire contains special elements, its weldability and impact values are 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.
