Abstract
An apparatus and method for producing an exhaust processor comprising: a clamping device for applying a predetermined clamping pressure to clamp a case or other component of the exhaust processor about a substrate or other component of the exhaust processor to define a gap between the case and substrate; a measuring device for measuring a size of the gap during application of the predetermined clamping pressure, the measuring device including a clamping pressure control system for adjusting the predetermined clamping pressure of the clamping device in response to the gap measurement so that the gap size is within a predetermined range; and a welder for welding a portion of the case component to an other portion of the caset when the gap size is within the predetermined range. The measuring device also includes a camera for measuring the gap size. The measuring device measures the size of the gap by taking gap measurements at a plurality of predetermined locations about the second component and averages these measurements.
