摘　　要：本文研究了双电极奥氏体不锈钢焊条单弧焊电弧的静特性、焊接电流、电弧电压、焊芯间隙对双电极焊条单弧焊的工艺性能和焊缝成形的影响;通过热电偶测试技术,对双电极焊条单弧焊焊接过程中不同部位焊芯表面温升进行了测定.研究结果表明焊芯直径为4.0mm的双电极A102焊条,其合适焊接工艺参数为：焊接电流140-160A,电弧电压45V左右,焊条两芯间隙1.2-1.5mm,焊接板厚8mm的1Cr18Ni9Ti材料,焊缝成形良好.The influence of static characteristic, welding current, arc voltage and core wires gap of single arc welding of austenite stainless steel twin electrode on technological performances and appearance of welding were investigated. The surface temperature of different locations of core wires was tested by means of thermocouple. The result shows that the technology is feasible for material of 1Cr18Ni9Ti and the good formation of weld can be obtained under the condition of diameter of the twin A102 electrode φ4. 0mm, gap of two cords 1.2 - 1.5mm, welding current 140 - 160A, arc voltage about 45V.
