Complex structure welding parameter precise management and control system and welding method

Abstract

The invention relates to a complex structure welding parameter precise management and control system comprising a man-machine interaction unit, a parameter collection unit, an alarm unit, a code scanning unit, a welding operation unit and a welding monitoring unit connected with the man-machine interaction unit, the parameter collection unit, the alarm unit, the code scanning unit and the weldingoperation unit. The man-machine interaction unit is used for inputting preset technological information. The code scanning unit is used for reading a two-dimensional code containing welded workpiece information and welder information. The parameter collection unit is configured to collect welding parameters in real time in the welding process. The welding monitoring unit is used for verifying thewelded workpiece information and the welder information read by the code scanning unit. In the welding process, the welding monitoring unit compares the welding parameters collected by the parameter collection unit with parameters in a corresponding preset technology in real time, and the alarm unit and the welding operation unit are controlled to act according to the comparison result. The invention further relates to a welding method utilizing the complex structure welding parameter precise management and control system, the welding parameters can be monitored precisely, and the automation level is increased.

Description

technical field [0001] The invention relates to the field of welding, in particular to a complex structure welding parameter precise control system and a welding method. Background technique [0002] Welding is one of the most important processes in the production of rail vehicles. The impact of welding on product quality is key. However, as a special process, welding is complex in quality control. Welding elements, especially parameters, have a prominent impact on welding quality. Existing It is difficult to realize real-time monitoring and storage of welding parameters, and realize real-time control and traceability of welding quality. The Chinese invention patent with the application number 201620437547.2 discloses a real-time welding defect online monitoring device, which is characterized in that it includes a welding operating system, a welding control system and an intelligent control system connected to each other through a welding power source, wherein the welding op...
