Title:
METHOD FOR PREDICTING STRENGTH OF ULTRASONIC WELD JOINT
Document Type and Number:
Japanese Patent JP2018111131
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for predicting a strength of an ultrasonic weld joint.SOLUTION: A method used for predicting a strength of an ultrasonic weld joint 22 for a wire cable 10 includes: a step at which a wire cable is provided; a step at which a total weight is measured; a step at which a contaminant is removed; a step at which a solvent is removed; a step at which a weight is measured; a step at which a percentage of a weight of the contaminant is determined; and a step at which whether or not the percentage of the weight of the contaminant is less than a threshold. Determination for the percentage of the weight of the contaminant removed from the wire cable is based on an expression of [(Mb-Ma)/Mb]×100, in which Mb represents a total weight of the wire cable and the contaminant, Ma represents a weight of the wire cable. The threshold of the percentage of the weight of the contaminant is correlated to a strength of the ultrasonic weld joint 22.SELECTED DRAWING: Figure 1B
