چکیده:

Inversion imaging of nugget in resistance spot
welding (RSW) is a new developing method of monitoring the
welding quality in RSW in recent years, which is based on the
rapid developments of the inverse problems in mathematics
and physics. This paper does some research on the forward
problem of inversion imaging of nugget and establishes the
forward model of RSW on the basis of the forward theory and
the electromagnetic field theory. And the soft wares of
MATLAB and ANSYS are used to simulate the
electromagnetic field of the forward model. The model’s
reliability is verified by comparing the experimental results
with the simulated results, which makes a good foundation for
the inversion imaging of nugget in RSW.
