Abstract
Wire + arc additive manufacture (WAAM)promises high build rates and is well-suited to the manufacture of large structures.In-process measurements of layer height are critical for WAAM process control but are difficult to achieve due to the presence of bright arc light. In this paper, a novel coherent range-resolved interferometric (CO-RRI) technique is successfully applied to the measurement of layer heights during arc operation in a first step towards gaining full in-process control of deposition layer heights.
