Welding monitoring method

摘要: PROBLEM TO BE SOLVED: To provide a welding monitoring method for rapidly detecting the occurrence of defect and nonconformity every path by ultrasonic flaw detection even during work to easily correct conditions make repair prior shifting following path. SOLUTION: In this allowing constant on welded state weld part work, flow is carried out pair transmitting-receiving probes 7, 8 opposedly arranged surfaces base materials 9, 11 with groove be welded, held in between. case nonconformity, are corrected, part, it fed back allow welding.
