| Abstract: | New testing technologies instead of welding repairs. The present report concerning the topic “New testing technologies instead of welding repairs” describes possible solutions of testing non‐penetrated welded joints using ultrasonic testing. The types of solutions presented all have the same objective – to measure the actual magnitude of defects. Here, it should be stated that it is not true that the exact magnitude of imperfections may be measured by usual ultrasonic testing. The conventional ultrasonic measuring techniques are suitable for detecting imperfections. The determination of the actual magnitudes is not possible directly, but the comparison with artificial reflectors such as side drilled holes or disk shaped reflectors. The types of solution presented do not serve to compete with complex ultrasonic systems with sophisticated software. On the contrary – it has been tried to realise solutions suitable for practice with the least possible expenditure. |
