根据全位置立向下焊接的特点和要求，在对现有各类焊条渣系进行物理性能及工艺性能试验分析的基础上，通过大量的试验，确定了具有短渣特性的高氧化钛渣系及高发气量的微晶纤维作为电焊条的基本配方，并加入适量的铁砂，利用其在焊接时冶金化学反应中的放热反应，提高电焊条的熔敷效率。新研制的纤维素型电焊条，基本上满足了在全位置立向下焊时熔池及焊缝成型的控制；高的电弧吹力，大的熔深，打底时可以保证单面焊双面成型；高的熔敷速度以及良好的工艺性能和物理化学冶金性能的基本要求，比较性试验结果表明，新研制的纤维素型全位置立向下焊电焊条，其工艺性能已接近国外同类电焊条，并且其焊缝的内在性能，特别是韧性指标，已超过国外同类电焊条。
Based on the characteristics and requirements of all-position vertical welding, based on the analysis of the physical properties and process performance of various existing slag slag lines, through a large number of experiments, the high titanium oxide slag with short slag characteristics was determined And the high gas content of the microcrystalline fiber as the basic formula for welding electrodes, and adding the right amount of iron sand, the use of its metallurgical chemical reaction in the weld exothermic reaction to improve the welding electrode deposition efficiency. The newly developed cellulose-based welding electrodes basically meet the control of forming the weld pool and weld pool when the welding rod is positioned downwards in all positions. The high arc blowing force and large penetration depth ensure single-sided welding double Surface forming; high deposition rate and good process performance and physical and chemical properties of the basic requirements of metallurgy, comparative test results show that the newly developed Cellulose-based full-position down welding electrode, its process performance close to foreign similar Welding electrodes, and the inherent properties of the weld, especially the toughness index, has surpassed similar foreign welding electrodes.
