Combined Temperature and Force Control for Robotic Friction Stir Welding

Misalignment detection for friction stir welding or Enabling seam tracking for friction stir welding

This paper describes a technique for determining the position of the friction stir welding (FSW) tool with respect to the weld seam during welding. This technique is proposed for online misalignment detection or as a position estimator for in-process tracking of the weld seam for FSW.

Monitoring and Control in Friction Stir Welding

Friction Stir Welding (FSW) is a recently-developed technique where metals are joined together through mechanical stirring. FSW, often performed by robotic welders, is being used in an increasing number of industries such as aerospace, maritime and transportation. FSW has proven to be very effective and has replaced fusion welding and riveting in a number of manufacturing processes. In order to...

A novel friction stir welding robotic platform: welding polymeric materials

The relevance, importance and presence of industrial robots in manufacturing have increased over the years, with applications in diverse new and nontraditional manufacturing processes. This paper presents the complete concept and design of a novel friction stir welding (FSW) robotic platform for welding polymeric materials. It was conceived to have a number of advantages over common FSW machine...

Friction Stir Welding Process Optimization: Experimental Methods

Introduction The Friction Stir Welding (FSW) process is an innovative technique to join metals in the plasticity field, thus not reaching the melting temperature and consequently the liquid state as it happen in traditional welding processes. This feature of the FSW proved an enhancement of the fatigue behaviour and strength of the joints, leading some companies to adopt the process for the man...
