In　wire　and　arc　additive　manufacturing　(WAAM),　it　is　crucial　to　maintain　a　constant　travel　speed　in　order　to　achieve　a　uniform　bead　morphology　along　the　tool-path.　However,　this　requirement　is　always　violated　in　practice　because　the　welding　robot　has　to　slow　down　when　sharp　corners　with　high　curvatures　are　encountered　so　as　to　satisfy　the　dynamic　constraint.　The　consequence　is　excessive　fillings　(i.e.　humps)　around　these　sharp　corners,　which　not　only　increase　the　required　post　processing,　but　also　prevent　the　continuation　of　the　deposition　process　if　the　accumulated　errors　in　the　build　direction　become　too　large.　This　issue　greatly　limits　the　application　of　WAAM　in　the　fabrication　of　complex-shaped　components.　In　this　paper,　an　adaptive　process　control　scheme　(APCS)　capable　of　guaranteeing　a　uniform　bead　morphology　while　still　respecting　the　dynamic　constraint　is　proposed.　First,　the　APCS　divides　the　tool-path　into　several　segments　depending　on　whether　they　contain　sharp　corners.　Then,　for　each　segment,　the　APCS　automatically　selects　the　allowable　travel　speed　subjected　to　the　dynamic　constraint,　and　also　the　wire-feed　rate　according　to　a　process　model　established　in　advance.　Through　the　matching　between　the　travel　speed　and　the　wire-feed　rate,　a　uniform　bead　morphology　among　different　segments　is　achieved.　Experiments　were　conducted　on　a　gantry　robot　using　the　Cold　Metal　Transfer　(CMT)　process,　controlled　by　a　self-developed　computer　numerical　control　(CNC)　system,　validating　the　efficacy　of　the　proposed　scheme.
