System for multi-signal collecting of welding process and movement control of welding platform

Abstract

The invention discloses a system for multi-signal collecting of welding process and movement control of a welding platform. The system is characterized in that a welding electric signal sensing device is used for collecting welding current and voltage, converting a collected electric signal into a voltage signal, and transmitting the voltage signal to a PC (personal computer); an electric arc sound collecting system is used for converting a collected sound signal into a voltage signal, and transmitting the voltage signal to the PC; a high-speed camera device is used for transmitting a shooting droplet transfer image signal to the PC through an industrial Ethernet bus; the serial communication is performed between a servo motor movement device and the PC through an RS-232 bus; the PC is used for receiving the data sent by the welding electric signal sensing device, the electric arc sound collecting device and the high-speed camera device, and storing the data into a local; the PC is used for controlling the movement of the servo motor movement device according to an instruction inputted by a user. The system has the advantages that the PC is used for remotely controlling the welding platform; multiple signals can be collected, so a good analysis platform is provided for the optimizing of welding technology and the studying of welding electric arc mechanism.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a multi-signal acquisition and welding platform motion control system in the welding process. Background technique [0002] With the increasing exploitation of offshore oil resources in recent years, more and more offshore oil drilling platforms and offshore pipelines need to be built, assembled and repaired, and the importance of welding technology has become increasingly prominent. As the depth of offshore oil exploitation increases, the welding environment becomes harsher, and pressure has a greater impact on welding quality, which puts forward higher requirements and challenges for welding, especially underwater welding technology. [0003] In order to obtain better weld quality and higher welding efficiency, it is necessary to develop new underwater welding techniques and improve existing welding techniques to solve a series of problems in the current underwater welding pro...
