    摘要： A special angle beam probe for ultrasonic testing includes at least one ultrasonic vibrator fastened in a beam probe housing on a wedge-shaped support body which may be formed of Plexiglass, using damping means. The ultrasonic beam of the vibrator strikes the surface of the test piece at an incidence angle other than 0.degree., as measured from a perpendicular at the surface of the test piece at the point where the beam strikes. The ultrasonic beam furthermore strikes the test piece surface at an oblique angle between 0.degree. and 360.degree. subtended between a principal beam probe axis and the beam, as seen in the direction perpendicular to the beam probe from above. The novelty of the invention is that the special angle beam probe includes a multiplicity of prefabricated beam probe subassemblies. The ultrasonic vibrator of each subassembly is fastened with a predetermined incidence angle within a first beam probe housing. A second beam probe housing contains the test head subassembly and the test head subassembly can be fastened at least at one predetermined oblique angle within the second housing for forming the overall special angle beam probe. In this way a multiplicity of beam probe subassemblies with the same insonification angle form special angle beam probes with different, predetermined oblique angles, by assembling the subassemblies in second test head housings in different oblique angle relationships.

    摘要翻译： 用于超声波测试的特殊角度束探头包括至少一个超声波振动器，该超声波振动器使用阻尼装置固定在可由有机玻璃形成的楔形支撑体上的束探针外壳中。 振动器的超声波束以不同于0度的入射角撞击试验片的表面，从在试样的表面处的垂直方向测量。 超声波束在主光束探针轴与光束之间以0°和360°之间的倾斜角度进一步撞击测试片表面，如从垂直于光束探头的方向看的那样。 本发明的新颖之处在于，特殊角度束探头包括多个预制的束探针组件。 每个子组件的超声波振动器以预定的入射角度紧固在第一光束探测器壳体内。 第二光束探测器壳体包含测试头子组件，并且测试头子组件可以在第二壳体内至少固定一个预定的倾斜角度，以形成整个特殊角度的光束探头。 以这种方式，通过以不同的倾斜角度关系将子组件组装在第二测试头壳体中，具有相同声子角的多个光束探测子组件形成具有不同的预定倾斜角度的特殊角度光束探头。

    摘要： A failsafe weld-free method of joining tubular elements provides for connecting a first tubular element to a second tubular element. The assembly includes an insert, with screw threads, inside of the first tube, a connector fitting for mounting to the insert within the first tube by a screw, a second tube is secured to the connector fitting with a fastener through a transverse hole through both the second tube and the connector fitting. When the connector fitting is assembled to the first tubular section and the connecting screw is tightened, a structurally rigid connection is achieved. The second tubular section is positioned over the stepped outside diameter of the connector fitting, aligning the transverse holes. A fastener is installed through the transverse hole. The fastener that secures the connector fitting to the second tubular section is positioned to not allow the screw fastening the connector fitting to the first tubular section to disengage or loosen. The resulting joint is structurally rigid in all planes without a visible fastener on the first tubular section with no distortion to the tubing due to bolt torque.
