A monitoring method for bogie digital welding specification

Abstract

The invention discloses a bogie digital welding standard monitoring method, and belongs to the technical field of bogie welding of railway vehicles. By utilizing output port numbers of welding monitoring equipment and internal numbers of a welding robot and programming setting codes, reset codes and logic signals, welding program information which is automatically operated by the welding robot can be fed back to the welding monitoring equipment in a signal mode constantly and the parameter monitoring of the whole welding process of the product is completed. According to the bogie digital welding standard monitoring method, the technical problem of information transmission between the welding robot and the welding monitoring equipment is solved, the real-time information interaction between the welding monitoring equipment and the welding robot can be effectively realized, and the parts and welding joints of all the layers and all the passes are automatically identified according to the welding program so that the whole process of welding and monitoring can be integrated; and the bogie digital welding standard monitoring method can guarantee that in the welding production operation, the welding monitoring equipment can accurately monitor the real-time welding parameters of the welding robot, the welding joint forming quality can be improved, the labor intensity of workers can be reduced, the utilization rate of the welding robot can be improved, and the qualified rate of the product can be improved.

Description

technical field [0001] The invention belongs to the technical field of rail passenger car bogie welding, in particular to a method for monitoring digital welding specifications of a bogie. Background technique [0002] At present, most of the real-time welding parameters of the beam and side beam welding process of the bogie are not monitored. This is mainly due to the complex structure of the product and the large number of welds and 95% of the welds are multi-layer and multi-pass welding. Welding parameters, it is difficult for monitoring equipment to distinguish the sequence of weld bead and correspond to welding parameters one by one. At the same time, traditional manual MAG welding is gradually replaced by welding robots. Welding monitoring equipment cannot identify the welding program automatically run by the robot, cannot control the welding program information, and is difficult to monitor the real-time progress of the welding process. In order to ensure the forming ...

AI Technical Summary

Problems solved by technology

[0002] At present, the real-time welding parameters of the welding process of beams and side beams of most bogies are not monitored. Welding parameters, it is difficult for monitoring equipment to distinguish the sequence of welding passes and correspond to welding parameters one by one

At the same time, traditional manual MAG welding is gradually replaced by welding robots. The welding monitoring equipment cannot recognize the welding program automatically run by the robot, cannot control the welding program information, and is difficult to monitor the real-time progress of the welding process.

In order to ensure the forming quality of each weld, the operator can only observe the state of the molten pool during the welding process through the traditional visual method, and the operator cannot effectively observe the real-time changes of the welding parameters, and it is difficult to distinguish whether the welding procedure is in accordance with the WPS The welding parameters required by the document are produced, so that the welding robot cannot accurately, efficiently and continuously perform standardized welding production operations according to the process requirements
