Welding quality management system

Abstract

The invention discloses a welding quality management system which comprises a welding quality management overall system server, a welding information acquisition system and a nondestructive inspection management system which are in networking connection. According to the welding quality management system disclosed by the invention, under the condition that an original welding machine is not changed, comprehensive online monitoring of actual welding parameters in the welding process is realized by adopting a non-invasive monitoring device and the reforming cost of enterprises is reduced. In addition, a non-invasive sensing acquisition module is suitable for welding machines with different model numbers and parameters and has higher generality; meanwhile, the troublesome of wiring is omitted, and thus the system is convenient to maintain; the welding quality management system has strong ant-jamming capability in a serious industrial field environment; and a user can realize comprehensive sensing of the welding process at lower cost and obtain important process data which cannot be monitored by a traditional mode or technology online.

Description

technical field [0001] The invention relates to the technical field of welding quality management, in particular to a welding quality management system based on Internet of Things technology. Background technique [0002] Welded structures (pieces) have been widely used in modern science and technology and production. With the continuous development of welding structures in the direction of high parameters, large-scale and heavy-duty, higher and higher requirements are put forward for welding quality. At present, the welding quality inspection process is separated from the welding process. Most of the welding operation units have been in an extensive production mode for welding production management, quality supervision and inspection. It is difficult for process and quality inspection personnel to monitor the welding operation process in real time. After the welding is completed, it can rely on methods such as ultrasonic testing or radiographic testing to check whether the...

Problems solved by technology

Although these systems can monitor welding parameters and equipment operating status in real time, and effectively track quality problems, since each monitoring point is combined with the welding machine, the layout of the monitoring points is inconvenient, cannot be moved at will, and has low flexibility; communication methods : Shandong Aotai uses twisted pair communication, the wiring construction is more cumbersome, and the welding machine needs to be re-wired when it needs to be re-determined. The short circuit of any bus line will make the whole system unable to work normally and the fault point is complicated to find, which increases the system. Difficulty of maintenance; Jinan Sapporo uses wireless communication, but needs a base station, and the communication distance is short

Moreover, the existing system can accommodate limited monitoring points (up to 46), and the scope of use is very limited

[0004] Chinese invention patent 200910247527.3 (publication number CN 101801115A, publication date is August 11, 2010) discloses a steel pipe welding data collection and processing system based on a wireless sensor network, although it can realize data collection, processing, Comprehensive monitoring of quality, but the use of barcodes to track welding quality has the following shortcomings: (1) Scanning equipment can only receive barcodes within the field of vision; (2) Barcodes are easily polluted and scratched in harsh factory environments, resulting in unrecognizable scanning equipment
