In this article, it expatiated the phase lock circuit, HFW pipe circuit and the basic principle of phase-locked loop, and detailedly analyzed design, application, adjustment and maintenance of phase lock in HFW pipe production line. Practice proved that the phase-locked loop possesses functions of frequency automatic tracking and phase automatic control. For frequencies below 1 MHz, using phase-locked loop CD4046 as phase locked circuit for HFW pipe is very practical, the circuit is simple, anti-interference, reliable operation, and it is enough to guarantee the high frequency welded pipe reliable work.
