Patent application number | Description | Published |
20110284508 | WELDING SYSTEM AND WELDING METHOD - A welding system has: a welding mechanism, a reception laser light source, a reception optical mechanism, an interferometer, a data recording/analysis mechanism and a data recording/analysis mechanism. The reception laser light source generates reception laser light so as to irradiate the object to be welded with the reception laser light for the purpose of detecting a reflected ultrasonic wave obtained as a result of reflection of a transmission ultrasonic wave. The reception optical mechanism transmits, during or after welding operation, the reception laser light generated from the reception laser light source to the surface of the object to be welded for irradiation while moving, together with the welding mechanism, relative to the object to be welded and collects laser light scattered/reflected at the surface of the object to be welded. | 11-24-2011 |
20110286005 | WELDING INSPECTION METHOD AND APPARATUS THEREOF - A welding inspection method has steps of: generating transmission laser light for generating an ultrasonic wave and transmitting the transmission laser light to an object to be inspected during or after welding operation for irradiation; generating reception laser light for detecting an ultrasonic wave and transmitting the reception laser light to the object to be inspected for irradiation; collecting laser light scattered and reflected at surface of the object to be inspected; performing interference measurement of the laser light and obtaining an ultrasonic signal; and analyzing the ultrasonic signal obtained by the interference measurement. At least one of the transmission laser light generated in the transmission laser light irradiation step and the reception laser light generated in the reception laser light irradiation step is irradiated onto a welded metal part or a groove side surface. | 11-24-2011 |
