GB/T 10045 T49ZT11-1NA AWS A5.20 E71T-GS

Application: It is suitable for welding structural steel with a tensile strength grade of 490 MPa. It is mostly used for all-position semi-automatic welding of carbon steel base metals (mainly thin plates and galvanized sheets), and is convenient for household operation. Common application areas include construction machinery, engineering machinery, etc.

Characteristics: Self-shielded flux-cored welding wire features a soft and stable arc, low spatter and attractive weld formation. Its outstanding characteristics include low fume emission, simple operation and excellent welding performance.
