AWS A5.18 ER70S-8 Solid wire
TEMO G4Si1, ISO14341-A-G42 3C1 4Si1
Description:
G4Si1 solid welding wire adopts advanced wire surface cleaning and electroplating coating technology, endowing the welding wire with functions of conductivity, arc stability, lubrication, and rust prevention. CO₂ or argon rich gas can be used for protection during welding, which has excellent welding process performance, beautiful weld formation, small spatter, good arc initiation performance, and less welding dust.
Diameters: Packaging:
0.6mm-4.0mm 1kg, 5kg, 15kg, 250kg, 300kg, 350kg
Applications:
Mainly used for welding carbon steel and low structural steel with a tensile strength of 500MPa, it can also be used for high-speed welding of thin plates and pipes.
