FIELD: physics. ^ SUBSTANCE: method for automated contactless and nondestructive inspection of joints of materials (4), where the operational threshold value (Wop) is varied in a range between a minimum threshold value (Wmin) and a maximum threshold value (Wmax), and where the same regions (B) are determined, which include values of the behaviour of heat flux (W) passing through the joint of materials (4), which exceed the operational threshold value (Wop). These regions (B) of the behaviour of heat flux are analysed for abrupt change in their perimetre. Such an abrupt change in their perimeter occurs when there is crossing of the boundary (7) between the fused zone (5) and the unfused zone (6), in which interfaced parts are still attached to each other. ^ EFFECT: improved method. ^ 10 cl, 5 dwg |
