The invention relates to a welding technological parameter selection method, more specifically relating to a welding parameter recorder. The welding parameter recorder comprises a sensor test module, a lower computer data acquisition module, a data display human-machine interface module, a wireless communication module, and a host computer data record analysis and display module. Real-time welding parameters of current, voltage, gas flow, temperature, welding speed, feeding speed and the like in a whole welding process are obtained in the sensor test module and the lower computer data acquisition module. Through a wireless data transmission device, parameters are sent to a management office. Parameter record processing software on a computer carries out operations of record, playback, analysis, contrast, statistics, printing output and the like on the parameters and real-time waveforms. The invention has the characteristics of low power consumption, strong anti-interference capability, convenient information transmission, no restriction of welding machine brands and models, wide application scope and the like.
