中文摘要：

将受控脉冲穿孔等离子弧焊接系统应用于中厚度板的对接焊。对接焊工艺中板间存在的缝隙会对尾焰电压测量结果和穿孔状态带来不利影响,造成控制系统对穿孔状态误判而达不到良好焊接效果,需要对系统进行改进实现良好穿孔过程。基于受控脉冲控制策略和工件合理的装配,避免等离子弧从对接工件缝隙透过而引起的系统误判。开展6 mm和8 mm厚度304不锈钢平板的对接焊控制试验,找到合理的工艺参数。设计一组变厚度不锈钢板对接试验,考察系统在对接焊条件下的控制效果。控制系统根据测量的表征穿孔状态的尾焰电压信号,实时调节焊接电流峰值及其下降沿斜率;随着板厚的减小,系统做出快速调节,一脉一孔的动态过程平稳,控制效果显著,焊缝成形质量良好。
