Evaluation method and device for examining operation condition of welders

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.
