摘　　要：针对某微波组件的电子束焊接过程,采用有限元法对焊接变形进行了模拟分析,并对焊接电流和焊接速度参数进行了优化。结果表明,理论计算值与实际测量值是完全吻合的,增加焊接电流或降低速度会加大焊接变形。该法对工程实践具有指导意义。The distortion of a microwave module in electron beam welding process is simulated by finite element method, and welding current and welding speed is optimized subsequently. The result shows that the final distortion in theory is fit to practical value. Increasing welding current or reducing welding speed can increase welding deformation. This method can be a useful guidance to engineering practice.
