APPARATUS FOR REAL-TIMELY WELD EVALUATION USING ACOUSTIC EMISSION AND THE METHOD THEREOF

摘要

The present invention relates to a device and method according to the real-time evaluation welding weld acoustic emission measurement , during the welding process and a sound wave detecting unit that is arranged adjacent to the welding portion so as to detect the sound waves emitted from the weld zone , sonic detection and filter unit to filter the sound wave signal is detected in the unit , and sound wave amplifier for amplifying the filtered signal , transmits the amplified sound wave signal based on the comparison and analysis of data received by the sound wave signal for determining a defect in the weld zone and consists of the calculation processing of the weld is determined in the arithmetic processing in a configuration that includes a sonic weld defect output for outputting a defect , the real-time quality of the welded part of the welding can be evaluated .
