前言在大规模的年产几十万、上百万的各类阴极射线管的流水线作业中,电子枪组装点焊机的电极性能将直接影响着生产线的工作质量和工作效率。在大批量的流水作业中,每班次的作业定额和焊接质量一般都要求较高,因而要求在作业中,尽量不用修整和打磨电极,不用调整电压和频率。这就对焊接电极的性能提出了很高的要求。 Preface In the large-scale production line with annual output of hundreds of thousands and millions of cathode ray tubes, the electrode performance of the spot welding machine with the electron gun assembly will directly affect the work quality and work efficiency of the production line. In high-volume assembly line work, the job quota and welding quality of the shift are generally higher, requiring the operation, try not to trim and polish the electrode, do not adjust the voltage and frequency. This places a high demand on the performance of the welding electrode.
