Abstract
A method for manufacturing a catalytic converter comprising disposing a first end around a second end and disposing an induction coil around the first end. Discharging a current through the induction coil and forming eddy currents on the surface of the first end. This magnetic impulse welds the first end and the second end together such that the first end disposed around the second end comprises a tube end disposed around an end of a catalytic converter or such that the first end disposed around the second end comprises the catalytic converter end disposed around the tube end. The method can be used to weld pieces of the catalytic converter, as well as sizing the catalytic converter for a desired mat density.
