Catalyst substrates and method of forming using capacative discharge welding

Abstract

A fixture for welding a substrate using capacitive discharge welding includes a support plate having a receiving portion. A back plate that is generally planar is positioned adjacent a rear wall of the support plate and perpendicular thereto, wherein the support plate and back plate are made from a non-conductive material. Another fixture for welding a substrate includes a pair of support plates having a cut-out forming a receiving portion. A back plate that is generally planar is positioned adjacent a rear wall of one of the support plates, wherein the support plate and back plate are made from a non-conductive material. A method of welding a substrate using capacitive discharge welding is also provided.
