步骤一、安装模具，将相关数据(批次、规格、材质、管号等)输入140MPa水压机的软件中，将衬管***基管装配于水压机，进行装配密封，移动及装配过程中应注意不要碰伤管端；
步骤二、启动水压复合在线应变监测***，记录双金属复合管未加压时的管径，然后开始向双金属复合管内部缓慢注水加压，在加压过程中双金属复合管会发生径向变化；
步骤三、在水压复合的同时监测双金属复合管的管径，依据管径变化的大小，及时调节水压复合时设定的压力值，控制水压复合的质量和效果，可以有效保证水压复合的效果，控制和提高管材的质量。
具体包括以下步骤：
步骤一、在140MPa水压机上安装对应的模具，同时将计算得出的复合所需的压力值等数据输入控制器，将衬管***基管内部，进行装配密封，在基管开设两个排气孔，水压复合过程存在于双金属复合管内外两层金属间隙中的空气可由排气孔排出，将双金属复合管装配上水压机，移动及装配过程中应注意不要碰伤管端；
步骤二、启动水压复合在线应变检测***，使用激光位移传感器1测量此时 与双金属复合管表面的间距，将此间距设定为零点，然后启动水压机开始缓慢加压，双金属复合管随着压力产生的变形，激光位移传感器1实时监测位移信号并转换成电压信号，然后激光位移传感器1将电压信号实时传递给动态应变仪3，动态应变仪3与测试电脑5通过USB电缆4相连，工作人员可以在后端的测试电脑5上观测试件的检测数据和状态，可以实时人工观测数据或设定上限阈值，来判定试件检测结果；
步骤三、使用水压复合在线应变检测***实时激光位移传感器1和基管表面的间距变化，通过后方测试电脑5转变为双金属复合管的径向变化，依据管径变化的大小及操作***的反馈，及时调节压力值，避免产生复合管的管径超出许可限制的情况，从而控制水压复合的质量和效果。这里用户可以通过测试电脑5获取径向应变结果，自行通过操控水压复合设备7的控制器控制水压；或者测试电脑5将径向应变结果与设定的阈值比较，若超出阈值，则发送控制指令控制水压复合设备7调整水压。
本发明使用由激光位移传感器1和数据采集仪组成的水压复合在线应变监测***，数据采集仪包括动态应变仪3和测试电脑5。监测***主要用于在水压复合过程中测试复合管在加压时的管径变化。工作人员依据管径变化的大小及操作***的反馈，及时调节压力值，避免产生复合管的管径超出许可限制1.5D％的情况，从而控制水压复合的质量和效果。本发明***为非接触测量，在不改变原有工装和打断生产工序的情况下，仅需要事前安装线路和传感器，就可以测量管材轴线上的形变量，通过实时监控复合管形变值，在生产过程中可以根据形变值来调节水压复合时的应力大小和速率，从而控制和提高管材的质量。
本发明在测试前安装监测***，不需要在生产过程中操作，不会打断管材的装载、加压和卸载，不需要在管壁上贴应变片和工装，可以逐根连续实时在线测 量应变数据，根据应变及时调节水压复合的压力值，提高水压复合效果和效率，从而加强双金属复合管的质量控制，同时本发明***可以适应不同规格的管材，根据实际需求进行安装拆卸。
