Development of nickel base alloy covered electrode enicrmo-3 for all position welding

  • 摘要: 通过合理调整药皮中碳酸盐、氟化物及氧化物的比例,控制熔敷金属合金元素的含量,研制的镍基合金ENiCrMo-3型Ni625焊条具有优良的全位置焊工艺性,与国外ENiCrMo-3焊条工艺性能相当。各项性能均满足技术要求,具有优良的抗晶间腐蚀及抗热裂纹性能。

     

    Abstract: Nickel base alloy covered electrode ENiCrMo-3 type Ni625 for all position welding was developed by reasonably adjusting ratio of carbonate, fluoride and oxide in the electrode and controlling alloying element content of deposited metal. The results showed that all performances of the developed electrode can meet the requirement and it exhibits good technological performances in all position welding, excellent intergranular corrosion resistance and hot cracking susceptibility.
