A complex structure welding parameter precise control system and welding method

Abstract

The invention relates to a precise management and control system for welding parameters of complex structures, including a human-computer interaction unit, a parameter acquisition unit, an alarm unit, a code scanning unit, a welding operation unit and a welding monitoring unit connected to the above-mentioned units; the human-computer interaction unit is used for Input preset process information; the code scanning unit is used to read the two-dimensional code containing welding workpiece information and welder information, the parameter acquisition unit is configured to collect welding parameters in real time during the welding process, and the welding monitoring unit uses In order to verify the welding workpiece information and welder information read by the scanning unit, during the welding process, the welding monitoring unit compares the welding parameters collected by the parameter acquisition unit with the parameters in the corresponding preset process in real time, and controls the alarm unit according to the comparison results And welding operation unit action. The invention also relates to a welding method using a complex structure welding parameter precise control system, which can realize precise monitoring of welding parameters and improve automation level.

Description

Precise control system and welding method for welding parameters of complex structure technical field [0001] The present invention relates to the field of welding, particularly a complex structural 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, and the impact of welding on product quality is critical. However, welding is a special process, and the quality control is complicated. Welding elements, especially parameters, have a prominent impact on welding quality. It is difficult to achieve real-time monitoring and storage of welding parameters, and to realize real-time control and traceability of welding quality. Application Number A real-time welding defect online monitoring device is disclosed for the Chinese invention patent of 201620437547.2, which is characterized by: In: including welding operating system, welding control system and int...

AI Technical Summary

Problems solved by technology

Although the patent realizes the monitoring of welding parameters, the confirmation of personnel before welding and the confirmation of workpiece information are still mainly manual, and complete automation has not been realized, and accurate monitoring cannot be achieved for multi-pass welds.
