Presentations

Development of a new stitch friction stir welding gun and mechanical behavior of intersecting stitch welded AA 6016-T4 sheets. Dominik Walz, MPA Stuttgart, Germany

Kevin Colligan (CTC, Concurrent Technologies Corporation): Analysis of Torque Data from Friction Stir Welds in Aluminum

Effect of FSW tool geometry on the joint quality of AA2024-T3/AA7075T6 joints in butt configuration. Reza Beygi, INEGI, Porto, Portugal

Using Artificial Intelligence in the Computer Aided Manufacturing of Friction Stir Welds by Stephan Kallee, Simon Smith and Mike Lewis

Machine investment cost and tool wear of friction stir welding of battery trays of compact crossovers. Stephan Kallee, AluStir, Germany

Stephan Kallee, AluStir: Machine investment cost and tool wear of friction stir welding of battery trays of compact crossovers

VW and Ford: Compact Crossovers, Sandy Munro: „Some really fancy extrusions with some fancy welding and some fancy machining“, „Integrate the battery structure into the vehicle, having the battery and body work together“, Modular approach, Cost optimized materials, joining processes and interfaces

Alu^Stir Battery Tray, 1.3 x 1.7 m floor plate, Made from hollow aluminium extrusions, 14 parallel friction stir welds: 22 m weld length Cut off the start and stop or park the end hole in a suitable place, Benchmarking study is based on producing trays for 200,000 cars per year in Europe, 100 sec per car

Quality and Cost: aiCAM^stir Software, The vision is to develop a software-package that adjusts the parameters automatically based on CFD, analytical modelling, parameter monitoring, image analysis and non-destructive testing, aiCAM^stir Ontology, To predict the quality and cost of FSW based on parameters, variables and boundary values
