Abstract: A method and system are provided for repairing a nozzle ring having a defect adjacent a transition between a ring plate and an inner skirt of the nozzle ring, comprising: forming at least one cut to detach at least one of a portion of the inner skirt, a portion of the transition, and a portion of the ring plate, thereby forming a joint surface and removing at least a portion of the defect; providing a replacement ring including replacement components for the detached at least one of a portion of the inner skirt, a portion of the transition, and a portion of the ring plate; and attaching the replacement ring to the nozzle ring at the joint surface using one of brazing or welding.

IPC: G01N15/08

Abstract: A particulate filter inspection system for a particulate filter includes a compressed air source, a primary conduit, a controller, a probe, and a gauge. The compressed air source is configured to draw air from an air source. The primary conduit is configured to receive the air from the compressed air source. The probe is coupled to the primary conduit and communicable with the controller. The probe is configured to interface with a face of the particulate filter to provide the air to only a sector of the particulate filter. The gauge is configured to determine a pressure of the air within the primary conduit when the probe is providing air to only a sector of the face of the particulate filter. The controller is configured to receive the pressure from the gauge, compare the pressure to a target upper pressure, and provide an indication that the particulate filter is dirty if the pressure is not lower than the target upper pressure.

Abstract: A particulate filter inspection system for a particulate filter includes a compressed air source. A primary conduit, a controller, a probe, and a gauge. The compressed air source is configured to draw air from an air source. The primary conduit is configured to receive the air from the compressed air source. The probe is coupled to the primary conduit and communicable with the controller. The probe is configured to interface with a face of the particulate filter to provide the air to only a sector of the particulate filter. The gauge is configured to determine a pressure of a first portion of the air within the primary conduit when the probe is providing a second portion of the air to only a sector of the face of the particulate filter. The controller is configured to receive the pressure from the gauge and compare the pressure to a target upper pressure.

Abstract: A system includes a controller, a pretreating machine, and an additive manufacturing machine. The pretreating machine is coupled to the controller. The pretreating machine includes a pretreater structured to form an interface layer on a component. The additive manufacturing machine is coupled to the controller. The additive manufacturing machine includes a material feed and a forming beam. The material feed is configured to selectively provide a first amount of material on the interface layer. The forming beam is configured to substantially melt the first amount of material, thereby forming a first layer of a first material deposit on the interface layer.
