摩擦焊直接能量控制法是一种以摩擦能量为控制对象的闭环控制方法，采用先进的单片机测控技术及高精度的检测方法，直接检测驱动电机的实时输入功率以获得实时摩擦能量；并以此为闭环控制对象，对焊接过程进行控制．同以往开环控制法相比，克服了工艺参数的波动对接头质量的影响，从而大大减少了焊前工作量；同时也减少了人为因素对接头质量的影响，使焊接质量达到一个新水平。
The friction welding direct energy control method is a kind of closed-loop control method which takes the friction energy as the control object. It adopts the advanced single-chip measurement and control technology and high-accuracy detection method to directly detect the real-time input power of the driving motor to obtain real-time frictional energy. For closed-loop control of the object, the welding process control. Compared with the open-loop control method in the prior art, the influence of the fluctuation of the process parameters on the quality of the joint is overcome, thereby greatly reducing the workload before welding, and reducing the influence of human factors on the joint quality, so that the welding quality reaches a new level.
