Multi-arc and multi-wire submerged arc welding intelligent control system

Abstract

The invention discloses a multi-arc and multi-wire submerged arc welding intelligent control system. The multi-arc and multi-wire submerged arc welding intelligent control system comprises an upper computer and a programmable logic controller. The upper computer is connected with the programmable logic controller in a communicating mode. The programmable logic controller is connected to welding power source and welding executing agencies of a plurality of welding machines. According to the multi-arc and multi-wire submerged arc welding intelligent control system, an industrial tablet with a touch function is adopted to replace a traditional submerged arc welding controller, matching issue, type-in and adjustment of technological parameters are realized by a virtual keyboard on a screen, the human-computer interaction effect is good, and the idealized tool usage requirements of what you see is what you get are realized; and a DeviceNet means of communication is applied to concentrate control of a plurality of electric arcs on an interface, users are facilitated to operate to realize micro adjustment of multiple electric arc linkage, automatic matching issue of the parameters, real-time comparative analysis, process automatic recording and generation and export of a diagram are realized, and the reliability and traceability of control of the welding process are improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an intelligent control system for multi-arc and multi-wire submerged arc welding. Background technique [0002] In today's world, global competition is more and more reflected in the competition of economic and technological strength, while technological innovation is increasingly becoming the key to promoting economic growth and improving technological competitiveness. As an important part of enterprise technology strategy, technology acquisition mode is of great significance to the long-term development of enterprises. Multi-arc and multi-wire submerged arc welding is mainly used in the welding of large and thick plate structures, and these structures often have relatively high requirements for welding quality. However, most of the current submerged arc welding controllers are operated by physical buttons. It is difficult to realize authority management for the control of wel...

AI Technical Summary

Problems solved by technology

However, most of the current submerged arc welding controllers are operated by physical buttons. It is difficult to achieve authority management for the control of welding parameters, and the records of the welding process lack authenticity, which is not conducive to the control of welding quality and accident analysis.

The control system of multi-arc and multi-wire submerged arc welding is mainly separated control, that is, one controller only controls one arc, and the linkage and coordinated adjustment between multiple arcs are less effective.
