AC/DC. All-position welding. Because more alloying elements have been added, it has excellent plasticity and low temperature impact toughness. It has excellent welding performance, stable arc, fewer spatters, good slag detachability and higher deposition efficiency.Applications:Suitable for welding important carbon steel and low-alloy steel structures such as ships,bridges,and offshore oil platforms, ocean vessels, etc.Diffusible Hydrogen Content in Deposited metal: ≤4.0ml/100g(Glycerine Hydrogen Test)X-ray Radiographic Inspection:Degree I Chemical Composition of Deposited metal (%) Chemical Composition C Mn Si S P Ni Mo Cr V Guarantee Value ≤0.12 ≤1.60 ≤0.75 ≤0.035 ≤0.035 ≤0.30 ≤0.30 ≤0.20 ≤0.08 General Result0.0681.360.52A(%)0.0120.0170.0220.0100.0420.012 Mechanical Properties of Deposited metal Test Item R m (MPa) R eL (Mpa)A(%) KV 1(J)KV 2 (J) Guarantee Value ≥490 ≥400 ≥23 ≥47(-40ºC ) ≥27(-46ºC )General Result 520~580 ≥410 24~32 100~180 80~160 Reference Current (AC, DC+) Electrode Diameter(mm) φ2.5 φ3.2 φ4.0 φ5.0 Welding Current (A) 60~100 90~140 160~200 180~240
