Ultrasonic inspecting and scanning device of welding line

Abstract

The invention discloses an ultrasonic inspecting and scanning device of a welding line, comprising a main frame, an idler wheel mechanism and a scanning mechanism, wherein the idler wheel mechanism is connected with the main frame, the scanning mechanism is arranged on the main frame and comprises a slanting scanning mechanism, and the slanting scanning mechanism is provided with a slanting scanning arm which is configured aslant relatively to a welding line to be inspected. The main frame is rectangular, and four edges of the main frame are all provided with guide rails; the slanting scanning mechanism comprises two slanting scanning brackets, a slanting guide rail and two slanting scanning arms, wherein the slanting guide rail is connected between two slanting scanning brackets, and the slanting scanning arms are arranged on the slanting guide rails; one slanting scanning bracket is straddled on two guide rails of two adjacent edges of the main frame, and the other slanting scanning bracket is straddled on two guide rails of other two adjacent edges. The ultrasonic inspecting and scanning device of a welding line, which is provided by the invention, can effectively solve the problem of missed detection of horizontal defects, enlarge defect detection range, realize overall scanning of the welding line and reduce potential safety hazard.

Description

technical field [0001] The present invention relates to a welding seam ultrasonic testing and scanning device, in particular to a welding seam ultrasonic testing and scanning device that utilizes Time Of Flight Diffraction ultrasonic testing technology (hereinafter referred to as TOFD) to detect butt welds. Background technique [0002] According to my country's current regulations, standards and common practices, in the process of mechanical equipment manufacturing, a certain amount of ultrasonic testing is generally required for the butt welds formed after welding to ensure product quality. [0003] As one of the ultrasonic testing methods, TOFD technology can obtain ultrasonic images of the internal structure of the weld in real time, and has a high defect detection rate, reliability and measurement accuracy. TOFD technology must use a certain form of scanning device to fix and clamp the probe, so that the probe can walk along the weld on the surface of the workpiece and ...
