Welding information acquisition system of tele-operation welding robot

For monitoring of tele-operation welding robot applied in dangerous environment,welding information acquisition also plays an important role except 3D virtual working environment created using virtual reality technology to improve man-machine interaction. A data acquisition module was applied to collect welding current and arc voltage,and the information acquisition software of the welding robot was developed using Qt and C ++ language,which has main functions such as acquisition and wave graphing of welding current and arc voltage,capture and display of welding image by camera. The system has good cross platform performance and excellent safety performance. Successful welding tests were carried out which indicates that the welding information acquisition system is suitable for tele-operation robotic welding application.
