Welding process parameter recording and welding quality analysis system

Abstract

The invention relates to a welding process parameter recording and welding quality analysis system which comprises a data acquisition board card, a data analysis processing board card, an external storage module, a communication module and a liquid crystal display module. The data acquisition board card acquires welding related data and conveys the welding related data to the data analysis processing board card to perform data processing and analysis, the analyzed data are displayed through the liquid crystal display module and stored in the external storage module, or the analyzed data is conveyed to an upper personal computer (PC) or an access gateway to be processed uniformly through the communication module. Recording of various parameters, such as current, voltage, welding speed, wire traveling speed, protective gas flow, environment temperature and preheating temperature in a welding process is achieved. Acquisition frequency is high, process analysis of the welding process can be performed, the data can be processed in off-line mode, the data do not need to be conveyed to a PC terminal to be processed, and the data can be processed uniformly through the PC or network. The data can be displayed in real time, and a welding process can be arranged. When top and bottom limitation of a preset alarm is reached, alarm operation is triggered, and welding quality is improved.

Description

technical field [0001] The invention relates to a production parameter recording system, in particular to a welding process parameter recording and welding quality analysis system. Background technique [0002] The welding industry is developing very rapidly, and the automation level in various industries has also been significantly improved. Arc welding robots, spot welding robots, robot automatic production lines, etc. have been widely used in automobile production. However, major equipment industries such as boiler factories have a low level of automation because of the characteristics of traditional technology dominance, large scale, high investment costs for transformation, maintenance of the overall situation, and difficulty in transformation. In the welding process, the key parameters related to welding quality, such as welding voltage, welding current, preheating temperature, ambient temperature, wire speed, workpiece speed, etc., basically follow the traditional me...
