本文研究了焊条电弧力的测定方法。介绍了所研究的测定装置,解决了焊条电弧力测定中存在的主要困难。测定了典型焊条在正常规范下的电弧力,研究了影响因素。进而针对焊条药皮的关键成分大理石、萤石、长石等,研究了各单一成分含量变化对电弧力的影响规律。并初步探讨了手工焊条电弧力的来源。 This article studies the method of measuring the arc force of electrodes. The measuring device studied is introduced, which solves the main difficulties in the determination of the arc force of the electrode. The arc force of a typical electrode under normal conditions was measured and the influencing factors were studied. In addition, the influence of the content of each single component on the arc force was studied according to the marble, fluorite and feldspar, which are the key components of electrode coating. The origin of manual arc welding force was also discussed.
