Evaluation method and device for examining operation condition of welders

Abstract

The invention provides an evaluation method and an evaluation device for examining the operation condition of welders, which are used for carrying out remote supervision and control on the welders who carry out field operation so as to ensure the welding quality. Job numbers of welding machines used by all the welders who carry out operation on the field are monitored in real time; an operating welding power supply is remotely monitored; whether the gas flow, the welding current and the welding voltage meet the requirements of a welding process specification is monitored in real time; and whether the welding power supply abnormally supplies power is monitored and related data is recorded for calling. The device consists of three architectures, i.e. a console, a middle computer and a lower computer. The console communicates with the middle computer by the Ethernet. Three modes of CAN (Controller Area Network) wire communication, GSM (Global System for Mobile Communications) wireless communication and intelligent card application can be respectively adopted between the middle computer and the lower computer according to the working environments of the welding machines.

Description

technical field [0001] The invention relates to a welder assessment method, in particular to remote monitoring of welding process parameters in the welding process. Background technique [0002] The welding process is an important measure to ensure the welding quality and a set of technical regulations in the welding process. Generally, the process department formulates the welding process, including welding method, pre-weld preparation, welding material, welding equipment, welding sequence, welding operation, process parameters and post-weld heat treatment, etc. Welding machines generally provide a man-machine interface for welding personnel to set welding parameters. Welding personnel should not violate the welding process requirements and set welding parameters beyond the specifications during operation, otherwise it may cause abnormal operation of the welding machine, resulting in welding defects and poor welding quality. [0003] Usually the welding site environment i...

AI Technical Summary

Problems solved by technology

However, in a welding site where a large number of welders work at the same time, the traditional supervision and assessment mechanism is inefficient, and it is difficult to ensure that all welders operate in compliance with the specifications during the entire working time, and this will cause a waste of human resources
