| 摘 要： | 利用建立的铝合金脉冲MIG焊熔池CCD视觉传感系统,通过焊接工艺试验研究了脉冲电流模式、熔滴过渡形式、焊丝伸出长度、焊枪位置和焊接电压等焊接参数对熔池视觉传感效果的影响规律.结果表明,熔滴过渡形式对视觉传感效果影响最大,在合适的脉冲电流模式下,通过调整焊接工艺参数使熔滴过渡为小颗粒自由过渡,配合短弧焊接既可得到良好的焊缝质量和成形,又可保证视觉传感效果.

| Abstract: | The influence of the pulsed MIG(metal inert gas) welding parameters on visual sensing effects in aluminum alloy welding process was investigated by using designed CCD visual sensing system.By altering the welding parameters,the influence of welding current mode,metal droplet transfer mode and arc length on visual sensing effects were studied.The results show that the metal droplet transfer mode has great influence on the visual sensing effects and other parameters also have important influence on the visual sensing effects.Under the suitable welding current mode and small drop transfer mode,good weld appearance and satisfying visual sensing effects are realized with the short arc. |
