摘要

    摘要
  • 摘要: 为了实现传热、传质的解耦，提出了旁路耦合电弧焊接工艺（Arcing-wire PAW）.介绍了旁路耦合电弧焊接工艺的原理和系统组成，利用数据采集系统和高速摄像机对电信号和熔滴过渡进行同步采集，结合电信号变化和熔滴过渡行为分析不同焊接参数对熔滴过渡的影响.结果表明，送丝速度和MIG电流的变化改变了焊丝熔化的平衡位置，使得熔滴的过渡状态和频率发生了变化，焊丝垂直高度的变化使得焊丝充分利用熔池的热量实现稳定快速过渡.由于传热和传质可以分开控制且电弧形态在焊接方向被拉长，保证了高速焊接时焊接过程的稳定性.
    Abstract: To achieve the heat and mass transfer decoupling proposed bypass coupling arc welding process (Arcing-wire PAW). First introduced the bypass coupling arc welding process-Arcing-wire PAW principle and system components, data synchronize acquisition systems and the high-speed cameras were used to record the changes of droplet transfer, combined with changes in electrical signals and droplet transfer behavior of different welding parameters on droplet transfer. The results showed that the changes of MIG wire feed speed and MIG current all change the wire melting equilibrium position, so that the droplet transition state and the frequency changes, in addition, the changes in the height of the vertical wire can make full use of the heat bath to achieve stable and rapid transition. Because of heat and mass transfer can be controlled separately and arc shape is elongated in the direction of welding, ensuring high-speed welding and weld stability of the welding process.
