The 89mm of outside diameter pipe with 5mm of wall thickness was used as test pipe piece for this experiment on closed butt joint configuration by utilising Bridgeport 2216 CNC milling machine and orbital clamping unit specially designed to cater for this task and function. Several welded samples were produced on varying process parameters which were successfully joined by using a non-consumable tool with a flat shoulder and a cylindrical pin. © 2014 Owned by the authors, published by EDP Sciences. publisher: EDP Sciences date: 2014 type: Conference or Workshop Item type: PeerReviewed identifier: Ismail, A. and Awang, M.
