摘　　要：采用工控机实时检测系统,通过在焊接接头埋设热电偶的方法实时检测了GH4169高温合金惯性摩擦焊接过程中接头的温度变化历程,获得了接头轴向和径向的温度场分布,并结合摩擦机制分析了其变化规律。The temperature variation process in the GH4169 superalloy inertia friction welding joint is measured by means of embedding thermocouples in workpieces, using the temperature testing system based on an industry control computer. The temperature distribution in the axial direction and radial direction of weldments is obtained and the varying law of the temperature distribution is analyzed.
