Butt welding of DP600 steel to 5754 aluminum alloy using electron beam welding is performed using an oscillating beam by changing its diameter at a fixed frequency. The performance of the welding joint is evaluated using electron backscatter diffraction (EBSD) texture, energy dispersive spectroscopy (EDS), and residual stresses measurement. Beam oscillation at optimum diameter produced more deformable texture fiber components than that obtained without oscillation joints. The oscillating beam demonstrated 70 pct higher elongation and almost double impact toughness than those reported by its non-oscillating counterpart. Oscillation diameter beyond an optimum value revealed a tendency to form weaker joints with deteriorated elongation and impact strength.

使用电子束焊接将DP600钢与5754铝合金进行对接焊接，是通过使用振荡束以固定频率改变其直径来进行的。使用电子背散射衍射（EBSD）纹理，能量色散谱（EDS）和残余应力测量来评估焊接接头的性能。与没有振荡接头的情况相比，在最佳直径下的光束振荡产生的变形纤维成分更多。与非摆动梁相比，摆动梁显示出70％的伸长率和几乎两倍的冲击韧性。振荡直径超过最佳值时，显示出趋于形成较弱的接头的趋势，并降低了延伸率和冲击强度。
