22. The Mandrel-Less Fixture Setup for Orbital Friction Stir Welding of Pipe Joining

Nowadays, friction stir welding (FSW) has been popular in the welding industry because of its effectiveness and help to reduces time. FSW starts to grow in the welding industry to help in their services and goods. This paper is focused on mobile units or fixtures for friction stir welding of tubular products joining. Dimension and size are included in the detailed explanation in order to support the idea of design and fabrication of this fixture. This fixture is designed to support and hold the tubular sections during the friction stir welding process. This project is drafted using a computer-aided design (CAD) software to get the best result in the design for the 2D and 3D model. This fixture is focused on the mandrel-less fixture concept. A compatible and suitable bobbin tool needs to be used to enable the fixture as a mandrel-less type. Hence, it can be used in applying the FSW process to cater for tubular sections in real industrial needs and applications.
