Abstract In this paper, the influence of different pulse generators with their characteristic discharge frequencies on the process parameters of magnetic pulse welding (MPW) of aluminum EN AW-6060 tubes on steel C45 cylinders is analyzed. Experimental, numerical, and analytical investigations focus on the radial impact velocity v i , r , the time-dependent collision angle β t , and the impact pressure p i . The influence of the temporal course of the magnetic pressure p m t is discussed. It is shown that the minimum radial impact velocity required for welding with the same geometrical setup can be reduced significantly at low discharge frequencies compared to high ones. This is attributed to a different deformation behavior of the tubular flyer part and, consequently, more favorable collision angles. Geometric changes to the joining setup enable a targeted modification of β t and allow for a reduction of v i , r even at high-frequency systems. During the design of an MPW process it is essential to consider the pulse characteristics. The advanced analysis methods presented in this paper contribute to the targeted establishment of favorable collision conditions for MPW, taking the distinctive features of the applied equipment into account.

传单动力学对管子磁脉冲焊接的影响

摘要 本文分析了不同脉冲发生器及其特征放电频率对EN AW-6060铝管磁脉冲焊接(MPW)工艺参数的影响。实验、数值和分析研究集中在径向冲击速度 vi 、 r 、时间相关的碰撞角 β t 和冲击压力 pi 上。讨论了磁压 pmt 的时间进程的影响。结果表明，与高放电频率相比，在低放电频率下，具有相同几何设置的焊接所需的最小径向冲击速度可以显着降低。这归因于管状飞轮部分的不同变形行为，因此，更有利的碰撞角度。连接设置的几何变化可以有针对性地修改 β t 并允许即使在高频系统中也能降低 vi , r 。在 MPW 工艺设计期间，必须考虑脉冲特性。本文提出的先进分析方法有助于有针对性地为 MPW 建立有利的碰撞条件，同时考虑到所应用设备的显着特点。
