Item type:Publication, Access status: with files , Semi-stationary shoulder bobbin tool (S3BT): a new approach in high speed friction stir welding(2016); Next to the advantages, in Bobbin Tool Friction Stir Welding (BT-FSW) the excessive heat generated by both shoulders leads to an excessive degradation of the joint microstructure and a consequent loss in mechanical properties. During this work a new set of welding tools and a new unique experimental BT-FSW system was created. An analytical model was introduced, which identified the kinetic energy on the retreating side of the weld zone as a critical value in the modelling to indicate the experimental feasibility. The Semi-Stationary Bobbin Tool (S3BT) process variant has shown good results in reducing handling forces in combination with considerable high welding speeds of 3000 mm/min and low energy inputs. The adaption of the tool concept to articulated arm robots appears realistic.Publicationtype: Doctoral Thesis604 1618
