Abstract: A teaching experimental platform for monitoring and measuring multi-arc welding processes has been developed based on LabVIEW virtual development platform. Its hardware equipment includes touch displaying control module, data filtering module, signal sensing module and high frequency and high voltage signal isolation module. Its software system includes four software modules for monitoring and measuring arc welding of single wire gas metal, double wire gas metal, gas tungsten and plasma. Each software module can monitor and measure welding current signal, arc voltage signal and deposited metal temperature signal. The platform has been used in many innovative experimental projects. Teaching practice shows that it has good man-machine interface and intelligent function. The teaching platform and the innovative experimental projects have effectively enhanced the students' capability of applying modern scientific knowledge and making innovation in practices, which provide powerful support for training new engineering professionals.
