Title:
CONTROLLER, AND METHOD AND DEVICE FOR DETECTING FILLING RATE OF FLUX-CORED WELDING WIRE
Document Type and Number:
WIPO Patent Application WO/2021/237583
Kind Code:
A1
Abstract:
A controller (16), and a method and device (1) for detecting a filling rate of a flux-cored welding wire. The method for detecting a filling rate of a flux-cored welding wire comprises: acquiring the actual deflection when a bendable part (21) of a flux-cored welding wire (2) is bent to reach a preset curvature (S500); comparing the actual deflection with a preset deflection range (S501); and determining, according to a comparison result, whether an actual filling rate of the bendable part (21) is within a preset range (S502). By means of the method for detecting a filling rate of a flux-cored welding wire, whether a filling rate of a flux-cored welding wire (2) is within a preset range can be detected without peeling off the flux-cored welding wire (2), such that the production efficiency can be effectively improved, and the wastage of materials is also reduced.
