Abstract
The invention provides rocket tank circular seam ultrasonic detection equipment and a control method. The rocket tank circular seam ultrasonic detection equipment comprises a base (100), a headstock (200), a circular seam clamp (300), a supporting bracket (400), a tailstock (500), a gantry scanning platform and a rocket tank (800). Specifically, the headstock (200) and the tailstock (500) are arranged on the base (100); the rocket tank (800) is fixedly connected with the headstock (200) and the tailstock (500); a to-be-welded circular seam area of the rocket tank (800) is fixed by the circularseam clamp (300) and an internal inner supporting mechanism; according to the invention, the in-situ one-stop nondestructive detection requirement of a friction stir welding seam of the carrier rocket tank is met, and phased array ultrasonic nondestructive detection, three-dimensional imaging and automatic defect diagnosis and evaluation functions of the welding circular seam of the carrier rocket tank are realized; and the problems of low reliability, long period, low system maturity and the like of current manual scanning detection and defect evaluation are solved.
Description
technical field [0001] The invention relates to the technical field of ultrasonic testing, in particular to an ultrasonic testing device and a control method for a circular seam of a rocket tank. Background technique [0002] Aiming at the requirement of in-situ non-destructive testing for friction stir welding (FSW) welds of launch vehicle fuel storage tanks, an array ultrasonic transducer, in-situ online automatic detection system and The imaging software realizes the in-situ automatic detection and automatic defect assessment of the friction stir welding girth of the launch vehicle fuel tank, and solves the problems of low reliability, long cycle and low system maturity of manual manual scanning detection and defect assessment. [0003] Patent document CN111089900A discloses an ultrasonic testing device for longitudinal seams of steel pipes. It includes a flaw detector body and a probe, a connecting line is arranged between the flaw detector body and the probe, and a bra...
