| Abstract: | With Labview virtual instrument software development environment, we build automatic welding deviation identification systems with new high-speed swing arc sensor. This system describes the acquisition of welding electrical signal based on Labview, and the use of low pass filter for signal processing. Limit regional integration difference method is used to extract the error signal, through Labview interface visa to control the programmable servo drive, and the paper gives the entire software design methods and control processes of error recognition system. Experimental study is carried out. The results show that the method is feasible, and the tracking accuracy can meet the application needs. |
