Abstract:
This paper deseribeis
the basic principle, composition of control circuit and construction of
control software of intelligent controller for the robotic are welding
inverter and equipment. The experimental results show that MOSFET are
welding inverter power sources can be directly numeral controlled by
8097BH single-chip microcomputer, stastistic and dynamic characters and
welding sequences for CO2/MAG automatic welding can be
conveniently achieved, diagnosis of the welding process faults and
alarming can be realized, welding parameters can be changed, adjusted,
stored and called. Besides, it makes a complete welding system with the
are welding inverter, wire feeder and torch, and has only on/off
relationship with the robotic control cabinet. By changing PI
parameters, the dynamic character of inverter can be adjusted, this
makes the welding process stabler, spatter less, welding appearance
better, shows more advantages of robotic welding methods.
