Embodiment Construction
[0027] Flux-cored welding wire is processed by a welding wire forming machine. The forming machine first pulls the steel strip into a hollow welding wire, and then adds powder to the hollow welding wire to make it a flux-cored welding wire, and then coils it to take up the wire.
[0028] as attached figure 1 As shown, a method for detecting the powder percentage of flux-cored welding wire, after turning on the power of the tester, includes the following steps:
[0029] (1) Through man-machine preset limit and initial value of magnification, and input information such as I-shaped wheel number, job number, steel strip thickness and detection range, etc.,
[0030] (2) Start the operation of the welding wire forming machine;
[0031] (3) The speed V of the hollow welding wire before dosing powder is controlled by the transmission motor frequency converter 1 and the speed V of the flux-cored wire after adding powder 2 collected separately;
[0032] (4), the speed analog signal...
