摘要：
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 φ 4.0 mm, gap of two cords 1.2-1.5 mm, welding current 140-160 A, arc voltage about 45V.
