    摘要： An object is to provide a laser beam welding diagnosis apparatus and a laser beam welding diagnosis method, which enable diagnosis of a laser beam welding state by detection of whether or not a penetrated welding state is maintained in a laser beam welded portion. A configuration therefor is a laser beam welding diagnosis apparatus that performs diagnosis of a laser beam welded portion 5 of a welded pipe welded by butting both edges of a steel strip 1 against each other and irradiating a butted portion with a laser beam 7, and the configuration includes an imaging unit 8, which continuously captures images of a laser beam welding penetration side of the laser beam welded portion 5, a feature amount calculating unit 11, which calculates, from an image captured by the imaging unit 8, a feature amount of a jetted portion accompanying laser beam welding penetration, a welding diagnosis unit 12, which determines that a welding defect in the laser beam welded portion 5 has occurred when values of the feature amounts in a predetermined area of the images continuously obtained become equal to or less than a predetermined value for a predetermined duration or longer, and a display unit 13, which displays and outputs a welding quality state including the occurrence of the welding defect.

    摘要： According to the present invention, penetrators can be adequately determined as flaws. In particular, a welded zone 2 of a pipe 1 is subjected to ultrasonic flaw detection at least in a pipe axial direction, and the quality of the pipe is evaluated using observed values in units of a predetermined area in a pipe thickness direction and the pipe axial direction. The length of one side of the predetermined area is an ultrasound beam width or more and a pipe thickness or less. The quality of the pipe can be evaluated while shifting the predetermined area in the pipe axial direction by using an average value of the observed values within the predetermined area. The length of one side of the predetermined area can be made an ultrasound beam width or more and a pipe thickness or less.

    摘要： An ultrasonic flaw detection is performed to a welded portion 2 of a pipe body 1 in at least a pipe axis direction, a defect detection threshold value is determined based on the signal intensity difference between the total area of the defects existing in the region of an ultrasonic beam on a welded surface and an artificial defect, and a quality control of the pipe body is performed based on the defect detection threshold value. An equivalent defect diameter is determined from the defect density, which is determined from a desired quality level, on the welded surface of the welded portion of the pipe body in a pipe axis direction and the area of the ultrasonic beam on the welded surface based on the total area of the defects existing in the region of the ultrasonic beam, and the defect detection threshold value is determined based on the equivalent defect diameter and the signal intensity difference of the artificial defect.
