摘　　要：由于巴氏合金拥有过强的流动性容易导致虚焊,通过摆弧焊接技术可以控制巴氏合金焊缝的宽度和高度、分散焊接热量、改善焊缝的外观和力学性能。通过高速摄像技术可以观察不同摆弧参数和焊接速度下摆弧焊的动态行为特性、熔滴过渡的模式和焊缝的宏观形貌。研究不同熔滴过渡状态、熔滴大小、熔滴过渡频率对焊缝性能的影响,相较于非摆动焊接,摆弧焊可有效控制巴氏合金焊接时的热量分布,从而提高了焊缝的均匀性。这种精细的热量控制降低了虚焊风险,优化了焊缝的熔敷性能。Due to the strong fluidity of babbitt alloy,it is easy to cause virtual welding.By using swing arc welding technology,the width and height of babbitt alloy welds could be controlled,welding heat could be dispersed,and the appearance and mechanical properties of welds could be improved.By using high speed camera technology,the dynamic behavior characteristics,droplet transfer patterns,and macroscopic morphology of the weld seam could be observed under different swing arc parameters and welding speeds.Study the effect of different droplet transition states,droplet size,and droplet transition frequency on the performance of welds.Compared with non swing welding,swing arc welding technology effectively controlled the heat distribution during babbitt alloy welding,thereby improving the uniformity of welds.This precise heat control reduced the risk of virtual welding and optimized the fusion performance of the weld seam.
