Active portable welding joint intelligent detector

Abstract

The invention relates to an active portable welding joint intelligent detector which comprises an active heat source positioned above a welding joint position of a welding workpiece. The upper part ofthe active heat source is connected with an information detection and processing unit by a mounting bracket; a power supply module is respectively connected with the active heat source and the information detection and processing unit so as to provide a power supply to the active heat source and the information detection and processing unit; the information detection and processing unit comprisesan array-type infrared temperature detection module for detecting a temperature of a welding joint and a visible light and depth camera module for detecting luminosity of the welding joint; an information processing module is respectively connected with the array-type infrared temperature detection module and the visible light and depth camera module; and the information processing module is alsosequentially connected with a data storage module and a data transmission module. By the active portable welding joint intelligent detector disclosed by the invention, rapid evaluation on welding quality can be implemented; and compared to existing welding quality evaluation, the evaluation of the active portable welding joint intelligent detector has the advantages of light weight, convenience in carrying and low cost.

Description

technical field [0001] The invention belongs to the technical field of weld seam detection, and in particular relates to an active portable intelligent weld seam detector. Background technique [0002] As an important technical means of modern machinery manufacturing, welding technology is widely used in machinery manufacturing. During the welding process, it is inevitable that the welding direction will change due to human or non-human factors, which will lead to welding deviation; during the welding process, the change of welding parameters will directly affect the change of the shape of the weld, and then produce welding defects, seriously affecting welding quality. In the welding of important industries such as aerospace, nuclear power, chemical industry containers, high-speed rail manufacturing, and automobile ships, in addition to internal inspection requirements, strict inspections of weld appearance and surface defects are required. The quality inspection of the we...

Problems solved by technology

The X-ray method should use radiation detection, and radiation protection devices are needed to avoid radiation hazards, resulting in high cost and low safety; although magnetic flux detection does not pose a safety threat to the human body with hard rays, it has large electromagnetic pollution. There is a certain impact on the peripheral equipment and the environment; the ultrasonic flaw detection method has the advantages of high detection sensitivity and fast speed, but it needs to use ultrasonic couplant during detection, and has high technical requirements for operators. At the same time, ultrasonic transmitting and receiving devices Larger, it is difficult to realize welding of large-scale structural parts
