Detection method of automatic scanner using laser positioning for welded seam detection

Abstract

The invention provides a detection method of an automatic scanner using laser positioning for welded seam detection. According to the technical scheme, a walking control mechanism is adopted to control a waling mechanism to move so that a scanning mechanism arranged on the walking mechanism can be driven to automatically move and scan, and meanwhile, a distance measuring device is matched with a positioning reference device to ensure that the walking mechanism walks straight. By the adoption of the detection method of the automatic scanner using laser positioning for the welded seam detection,automatic scanning operation can be reliably and stably conducted without building positioning rails, linear scanning can be automatically conducted after the scanner is started, overmuch human involvement is unnecessary, usage is easy and convenient, requirements for detection staff are reduced, bad effects caused by manual misoperation are avoided, the detection efficiency is greatly improved,the labor intensity, the labor cost and the requirements on staff's techniques are reduced, and the detection period is shortened; automatic detection replaces manual detection, so that detection stability and reliability are ensured, and the detection method of the automatic scanner using laser positioning for the welded seam detection can be applied to scanning work at great heights or in severeenvironments.

Description

technical field [0001] The invention relates to the field of non-destructive testing of equipment, in particular to a testing method of an automatic scanner for welding seam testing using laser positioning. Background technique [0002] Due to the mutual competition in the product market, high quality is an important factor to improve competitiveness. From the point of view of product quality, this is important. From a purely economic point of view, reliability is also necessary in order to reduce the total expenditure. Non-destructive testing has played an important role in the quality assurance system and has become an important means to control product quality and ensure the safe operation of in-service equipment; for general non-destructive testing, quality inspectors often rely on flaw detection instruments for manual testing, which makes artificial Factors have a great influence on the test results. As an advanced ultrasonic testing method, phased array testing is use...
