چکیده :

This paper establishes a welding energy model and describes a hzzy adaptive process control
scheme for a resistance spot welding system.
For a welding system, it is not easy to measure with on-line the output, the nugget size, by usual
measuring method. And it is also difficult to control the welding process in real time . The paper
proposes a new method with input welding energy to estimate the nugget size and to reckon the
welding process. An optimal welding energy reference model is founded compared with different
input method of welding energy. A fizzy adaptive process control scheme with the model is also,
here, described to realize real time control and to improve control performance.
The results of simulation and experiments show that the reference model is effective on reducing
loss energy and prodiicing a sound nugget and the hzzy adaptive control scheme may obtain an
optimal control process for resistance spot welding
