Example Embodiment

[0037] The joining quality control method according to the present embodiment is performed on a friction welding member obtained by cutting off burrs generated on the outer peripheral side of the joining portion.

[0038] In the following embodiments, a case where the frictional welding member is a hanger rod which is one type of hanger member is shown as an example, but it is not intended to limit the application of the frictional welding member.

[0039] First, the structure of the frictional welding member will be briefly described.

[0040] like figure 1 As shown in (a), the friction welding member A to be inspected is formed by friction welding the end members A2 and A2 at both ends of the tubular member A1. Both the tubular member A1 and the terminal member A2 are obtained by processing extruded profiles made of aluminum alloy. There are no particular restrictions on the type of aluminum alloy, but in the case of using the friction welding member A as the suspension frame

Abstract

Provided is a joining quality management apparatus which allows for simple and speedy inspection of a joining state of a joint of a friction welded component obtained by cutting off a burr on the peripheral side of the joint occurring in friction welding. The joining quality management apparatus is provided with an imaging means (3) which images the peripheral surface of the joint (a) of the friction welded component (A), an extracting means (4) which extracts dark pixels having luminance values not higher than a reference luminance value from image data captured by the imaging means (3), a number-of-pixels summing means (5) which sums the number (N) of the dark pixels extracted by the extracting means (4), and a determination means (6) which determines whether a joining quality satisfies a management reference. The determination means (6) determines that the management reference is satisfied when the number (N) of the dark pixels is not larger than the reference number (N0) of pixels, but determines that the management reference is not satisfied when the number (N) is larger than the reference number (N0) of pixels.
