Non-destructive testing system performs accurate testing as to whether lamination joining portion of different metal materials is in strong joining state by secure metal joining. The system sets a lamination joining portion of different metal materials of a work to a certain position and angle. Laser light in certain waveform is applied to lamination joining portion surface to capture images by infrared camera, and data processing device obtains infrared images. Based on infrared images, Fourier transform is performed on each pixel of infrared images, and phase image is created by console device. Based on created phase image, effectiveness/defectiveness of joining is determined. In this non-destructive testing, whether reflection by vertical wall in vicinity is significant is determined, based on intensity of infrared images obtained immediately after irradiation with laser and angle between laser light optical axis and testing part surface is finely adjusted to obtain infrared images with less noise.
G01N 21/35 - CouleurPropriétés spectrales, c.-à-d. comparaison de l'effet du matériau sur la lumière pour plusieurs longueurs d'ondes ou plusieurs bandes de longueurs d'ondes différentes en recherchant l'effet relatif du matériau pour les longueurs d'ondes caractéristiques d'éléments ou de molécules spécifiques, p. ex. spectrométrie d'absorption atomique en utilisant la lumière infrarouge
The joints between the body section (12) of an automobile subframe (11) and suspension support members (13) comprise: first joints (A) at which an upper plate (14) is joined to the suspension support members (13) while the upper plate (14) is directly superposed on the suspension support members (13); and second joints (B) at which a lower plate (15) is joined to the suspension support members (13) while the lower plate (15) is directly superposed on the suspension support members (13). The first and second joints (A, B) extend in the front-rear direction of the vehicle in such a manner that each of the first joints (A) and each of the second joint (B) are not superposed on each other. The configuration enables a load applied to the suspension support members (13) from suspension arms (16) to be directly transmitted to both the upper plate (14) and the lower plate (15), and as a result, the joining strength between the body section (12) and the suspension support members (13) is increased. In addition, the upper plate (14) and the lower plate (15) are joined to the suspension support members (13) from the same side, and this eliminates the need to invert the attitude of a workpiece, improving work efficiency.
A beam member comprises: a slit section (16) formed at the axial center of a circular beam body (10) formed by rolling a flat plate-like member, the slit section (16) being formed by separating a first end section (12) and a second end section (14) of the beam body from each other, the first end section (12) and the second end section (14) facing each other in the circumferential direction of the beam body; a first welding section (18a) and a second welding section (18b), the first and second welding sections (18a, 18b) being those at which portions of the end surfaces (e, e) of the first end section and of the second end section, the portions being in contact with each other, are welded to each other while the first welding section (18a) and the second welding section (18b) sandwich the slit section in the axial direction of the beam body; and a bracket member (50) serving as a strength member, welded to the outer surface of the beam body so as to straddle the first end section and the second end section in such a manner that, between the first welding section and the second welding section in the axial direction of the beam body, the bracket member (50) covers the slit section.

An inspection unit (30) of a welding inspection device (1) comprises: a striking device having a striking member (104) for applying an impulsive force to a press-molded article made of metal, a drive mechanism (108) for applying a driving force to the striking member, and an urging member (110) for urging the striking member in the direction opposite the direction of application of the drive force of the drive mechanism; a microphone (120) into which are inputted sound waves generated from the press-molded article having been struck by the striking member; and a detection device (130) for detecting the welding state of the press-molded article in accordance with the waveform characteristics of the sound waves inputted to the microphone. In a state where the drive force from the drive mechanism is turned off and the striking member is urged by the urging member in the direction opposite the direction of application, the striking member applies the impulsive force on the press-molded article, and after having applied the impulsive force to the press-molded article, is forcibly pulled back by the urging member in the direction opposite the direction of application.
f) protruding outward from the outer circumferential surface of the elastic body to be brought into pressured contact with the internal circumferential portion of the coil spring when the elastic body is inserted into the internal circumferential portion of the coil spring.
B60G 11/52 - Suspensions élastiques caractérisées par la disposition, l'emplacement ou le type des ressorts ayant des ressorts de différents types ne comprenant pas des ressorts à lames ayant des ressorts hélicoïdaux, spirales ou en bobines et des ressorts en caoutchouc
Disclosed is a weld joint of an aluminum alloy member formed by joining one end of a wrought material (12) to one end of a cast member (11). The cast member has a chamfer (14), and an inserting portion (13) which extends from the lower end of the chamfer (14) toward the distal end of the cast member along the lower surface of the wrought material. The distance (L) from the lower end of the chamfer to the end face (12a) at one end of the wrought material is set equal to 1.0-1.7 times of the thickness (T) of the wrought material, and the chamfer is inclined so that the angle of a groove between the chamfer and the end face (12a) at one end of the wrought material is 15-45°.
