Estimating the term…
There is provided a welding wire remaining amount detection and warning system which relates to the welding field. The present disclosure aims to solve the problem of inability to detect the welding wire remaining amount in the laser composite welding makeup device. In the present disclosure, in the welding wire remaining amount detection process, based on electromagnetic induction principle, the equivalent inductance of the coil decreases along with decrease of the welding wire. The change of the equivalent inductance of the coil is converted by the LC oscillator circuit into a directly-collectable frequency change signal. By detecting the value of the current frequency, the current welding wire remaining amount can be determined.
A welding wire remaining amount detection system, comprising a detection coil, a detection circuit and a controller;
