Title: Weld examination for steel pipe
Inventor: KAWAMURA KOUJI
IPC: B23K31/00
Filed: 1980-04-18
Abstract: PURPOSE:To obtain an accurate weld examination by a method inwhich ultrasonic wave is projected perpendicularly on the pipe surface and multiple reflected wave forms from the inside surface of the pipe are checked. CONSTITUTION:An ultrasonic probe is scanned along a line crossing the weld line of welded steel pipe. Ultrasonic wave is projected perpendicularly on the surface of the pipe to get multiple waves reflected back from the inside surface of pipe. As the welded part is formed in such a shape as the ultrasonic wave projected perpendicularly on the pipe surface is scattered, there are differences in wave forms reflected from the inside surface of pipe between for the matrix material of pipe and for the welded part of pipe. The integrated value of echoes from the inside surface within a preset duration, grand sum of echo waves or attenuation characters of multireflected waves and so on are recorded and thereby these values are compared with each reference value or the characteristic curve previously designated to discriminate whether they are from the matrix material or from the welded part.

Filed: 1985-03-14
Abstract: PURPOSE:To plot an accident point at high accuracy by using a radio transmitter when a discharging pulse orienting to a remote terminal from the accident point is transmitted to a measuring terminal. CONSTITUTION:A calibrating pulse is impressed on the remote terminal of an accidental cable line 2, and a time difference deltat between a pulse detected at a measuring point through the line 2 and a pulse, which is radio-transmitted through a radio transmitter 4 and a radio receiver 6 and detected at the measur ing terminal, is measured by a synchroscope SS 9. Then it is assumed that a high voltage is impressed on the line 2 from a terminal 3 and the discharging pulse arises at the accident point A. Said pulse is detected as the 1st propaga tion signal S1 in the measuring terminal 3 of the line 2 by means of the SS 9. Moreover the discharging pulse is detected as the 2nd propagation signal S2 at the remote terminal of the line 2, and transmitted to the receiver 6 by means of the transmitter 4. At the measuring terminal 3 the SS 9 calculates a time difference DELTAt between the signals S1 and S2. Then a distance X from the measuring terminal 3 to the accident point A is obtained with the prescribed equation where the length of the line 2 and the propagation speed of the pulse through the line 2 are L and V, respectively.
