When our designers chose to make a butt fusion machine having more capability than a human operator, they knew that they must control THE WHOLE PROCESS, leaving nothing to chance. this meant combining the accepted jointing parameters with continuously monitored information and the operators input to give a system capable of responding correctly at all times.
It is particularly interesting to see how the LINEAR TRANSDUCER (continuously monitoring pipe shell movement) is able to assist us in:
1. Controlling the trimming process
2. Distinguishing between static and dynamic friction, for drag measurement. 3. Detecting for pipe slippage.
4. Controlling the speed of approach during fusion.
5. Controlling bead size.
6. Detecting early pipe removal prior to cooling.
