Description
Thermomechanical modelling of the friction stir butt welding process in AA 5083-H18 aluminium alloys was undertaken using a CFD (computational fluid dynamics) code to describe the steady state, and simulated temperature profiles were compared with the results from experimental thermocouple measurements. Temperature distribution and plastic deformation during friction stir welding were calculated by solving continuity, momentum and energy equations using temperature and strain rate dependent material properties. Welding experiments were performed at rotational speeds of 1000 or 1500 rpm and welding speeds of 100-300 mm/min. Temperature profiles and material flow patterns were computed under different process conditions.
