Applicable Steel Grades: Low carbon steel and 490MPa high-strength steel
Welding Method: FCAW-G
Wire Type: Titania type
Shielding Gas: Carbon dioxide
Filler Metal Form: Flux-cored wire
Polarity: DC reverse (DCEP)
Welding Position: All-position
Application: Suitable for welding low carbon steel and 490MPa high-strength steel, widely used in shipbuilding, bridges, construction, storage tanks, steel structures, etc.
Characteristics: All-position welding wire, suitable for both 100% carbon dioxide and 80% argon + 20% carbon dioxide as shielding gases. The diffused hydrogen content of the deposited metal is low, less than or equal to 5ml/100g, ensuring high crack resistance of the weld. It adapts to high-heat-input welding conditions and exhibits excellent mechanical properties when used with a ceramic backing for high-heat-input welding.
