ABSTRACT:
A method of connecting hollow conductors with a brazing alloy employs a measuring mechanism10for measuring a connecting state of a connecting portion after brazing hollow conductors. The measuring mechanism comprises a scanner101and a holder19, which are separated in advance, so that the mechanism can be installed in a narrow space. A display mechanism20displays measuring results as tow-dimensional patterns, and the evaluation mechanism30evaluate the connecting portions by an area of the defects and an integral length of sound portions. A judgment mechanism40evaluates relative relation of the measuring results with causes-and-defects, which are previously stored, and shows the cause of the defect.
