摘　　要：研究了钛钙型双电极焊条的两芯间距和焊接电流对单弧焊工艺的影响 .研究结果表明 ,钛钙型双电极焊条的两芯间距是控制焊接电压的最重要因素 ,焊接时调节双电极焊条与工件间距离对电弧电压影响很小 ,随双电极焊条两芯间距的增大 ,电弧电压升高 ;在两芯间距一定的条件下 ,随焊接电流增大 ,电弧电压线性升高 ;对于药皮重量系数为 45.6%的 2×Φ4mm钛钙型双电极焊条 ,在两芯间距为 1.2～ 1.7mm ,焊接电流为 180～ 2 2 0A的工艺条件下进行焊接 ,焊缝成形较好 。Investigates the influence of two cor es span and welding cur rent of lime tiannia type twin electrode on welding technology. Results show tha t the space between two cores of twin electrode is the important factor to contr ol welding voltage. Adjusting the space between twin electrode and work-piece h a s very little influence on welding voltage. Welding voltage goes up when welding current increases. Using twin electrode of 45.6% coating weight coefficient, wi th Φ4?mm, under the condition that the space between two cores is 1.2～1.7 ?mm and welding current is 180～220?A, weld that has good weld appearance and mechanics property can be gained.
