  • Berg Steel Pipe: Multiple-Wire Welding Creates High Productivity and Quality
    , Berg planes the plates to the precise required width and bevels the plate edges for longitudinal seam welding. This beveling operation prepares plate edges with a double V groove joint design for the upcoming welding operations. After plate edge preparation, the plate is formed into a rough tubular

  • Advances in Hand-Held Ultrasonic Thickness Gages with Live Color Waveforms (A-Scan) (.pdf)
    Ultrasonic thickness gages have progressed a long way since their early development in the 1960's. The first thickness gages were large and bulky although they used the same conventional longitudinal (compressional wave) techniques still in use today. Thickness gages are used in a wide variety
  • Ultrasonic Technique and Device for Residual Stress Measurement
    on the mechanical stress [3-6]. The relationships between the changes of the veloci-. ties of longitudinal ultrasonic waves and shear waves of orthogonal polarization under the action of tensile and compressive. external loads in steel and aluminum alloys are presented in Figure 1. As can be seen from Fig. 1
