Study of Forward Method on Imaging of Nugget in Resistance Spot Welding
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 models 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.
