Abstract

Weld profiles on curved surfaces, e.g. parallel vanes attached to heat exchanger tubes, may be measured by a dual compressed air system. This comprises a main feed nozzle delivering air at fixed static pressure, with attached manometer, and a secondary nozzle delivering air continuously at a given pressure. Variation in static pressure in secondary line is due to non-uniformity in weld geometry, and may be used to set off alarm signal or recording device. System is attached to wheeled carriage running between vanes with centralising rod at end.
