摘要: A welding system has: a mechanism, reception laser light source, optical an interferometer, data recording/ analysis mechanism and mechanism. The source generates so as to irradiate the object be welded with for purpose of detecting reflected ultrasonic wave obtained result reflection transmission wave. transmits, during or after operation, generated from surface irradiation while moving, together relative collects scattered at welded.
