Property analysis of submerged arc and self-shield fluxed-cored welding wires sufacing metal with ultralow carbon and nitrogen solid solution processing

According to the formulas of the ultralow carbon 00Cr13NiMoN series with nitrogen substitute for carbon submerged arc and self-shielded flux-cored welding wires,the transition form of nitrogen in the two wires was introduced.With the same surfacing parameters,the metallographic structure,hardness,resistance to tempering and abrasive resistance of the deposited metal were compared and analyzed.The results show that self-shielded flux-cored welding wires have better mechanical properties and wider applied scope than submerged arc welding wires in repairing the continue cast rollers.
