Mild Steel·490~550MPa High Tensile Strength Steel / CO2 Flux Cored Wire SX-55

Characteristics

SX-55 is seamless flux cored arc welding wire filled mainly with metallic powder and is used with CO2 shield gas. The arc is softer and the fume is less and the weld metal in holizontal position (2G) is bringed better than solid wires with CO2. And the penetration is gave as depth as solid wires with CO2. The continuous multi-layer welding like solid wires is possible due to the small amount of slag.
The wire is fed straight and easily since it has no seam and, therefore, is suitable for high current and high efficiency automatic welding including robots.
In case of welding for 490MPa high tensile strength steel, it can be applyed a administrative limited welding conditions (H/I: 40kJ/cm-Inter-Pass/Temp.: 350°C) on JASS6 of Arcitectual institute of Japan.

Applications

Welding of mild steel and 490 to 550MPa high tensile strength steel for construction of steel structural.
