Magnetic pulse welding (MPW) has potential applications where fusion welding is problematic, such as in dissimilar joints or where the very part integrity, as in electronic components, is likely to be impaired by hot environments. Mostly suited in lap configuration, its successful implementation hinges on multiple process parameters such as standoff distance between two parts, the discharge energy and the shape of inductor amongst others. From fundamental point, the impact angle and velocity are governing factors and remain difficult to apprehend via experimental approach. Numerical simulation is a viable tool to apprehend the effect of process parameters on impact angle and velocity and subsequently outline a physical weldability zone. On the contrary, the process weldability zone is experimentally determined for dissimilar joints made from A5754 on to DC 04 steel by varying the discharge energy and standoff distance using a straight I shape conductor. The shear strength of the joints is used as a marker to define the process weldability zone. Results suggest that weldability is reduced by increasing the discharge energy and standoff distance and a combination of two is required to optimize the outcome. The paper proposes to discuss process and physical weldability zones determined through numerical simulation and experimental tests.

电磁脉冲焊接（MPW）在有问题的熔焊中有潜在的应用，例如在异种接头中，或者在很热的环境下可能会损坏电子零件中的零件完整性。它最适合搭接配置，其成功实施取决于多个工艺参数，例如两个零件之间的间距，放电能量和电感器的形状等。从根本上讲，冲击角和速度是控制因素，仍然很难通过实验方法来理解。数值模拟是了解工艺参数对冲击角和速度的影响并随后概述物理可焊性区域的可行工具。反之，对于使用A5754与DC 04钢制成的异种接头，通过使用直I形导体改变放电能量和间隔距离，通过实验确定了工艺可焊性区域。接头的剪切强度用作确定过程可焊性区域的标记。结果表明，增加放电能量和间隔距离会降低可焊性，并且需要将两者结合以优化结果。本文提议讨论通过数值模拟和实验测试确定的工艺和物理可焊性区域。结果表明，增加放电能量和间隔距离会降低可焊性，并且需要将两者结合以优化结果。本文提议讨论通过数值模拟和实验测试确定的工艺和物理可焊性区域。结果表明，增加放电能量和间隔距离会降低可焊性，并且需要将两者结合以优化结果。本文提议讨论通过数值模拟和实验测试确定的工艺和物理可焊性区域。
