METHOD FOR EVALUATING A WELDED JOINT AND WELDED-JOINT EVALUATION DEVICE

摘要

A method for evaluating a welded between a first component and a second component comprises the steps of: bringing a first electrical pole into contact with the first component and bringing a second electrical pole into contact with the second component with the welded joint in between the first and the second pole; applying a first electrical quantity to the welded joint such that an electrical current (i) flows through the welded joint; measuring a second electrical quantity at the first and the second pole; comparing a measured value (Ω_F; U_F) of the second electrical quantity with a reference value (Ω₀; U₀); and evaluating the welded joint on the basis of the comparison step.
