Railway vehicle welding intelligent control system and method

Abstract

The invention discloses a railway vehicle welding intelligent control system and method. The railway vehicle welding intelligent control system comprises an input unit, a parameter acquisition unit, a parameter output unit and a control unit, wherein the input unit, the parameter acquisition unit and the parameter output unit are respectively connected with the control unit; the control unit comprises a welding rod type diameter determination module, a welding current determination module, an arc voltage determination module, a welding speed determination module and a real-time correction module, by optimizing and correcting the current, the arc voltage and the welding speed, the influence of subjective factors of welding workers is avoided, and the reliability of the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent welding, in particular to an intelligent welding control system and method applied to the rail vehicle industry. Background technique [0002] In order to meet the needs of social and economic development, since the beginning of the 21st century, in order to reduce the quality of the rail vehicle body itself, stainless steel is usually commonly used. The rail vehicle body made of stainless steel is mainly composed of four parts: the underframe, the roof, the side wall and the end wall. Usually, low-alloy high-strength steel and weather-resistant structural steel are generally used in key parts of the chassis. Most of the parts such as the side walls, roof and underframe of the stainless steel car body are welded by hand. There can be as many as 7000-8000 solder joints in one car body, and most of the solder joints are welded by manual calibration. [0003] There are many factors that affect...
