The inherent beam stiffness, bearing compliance, and control system for each machine were distinctly unique, which posed specific challenges in transferring welding parameters across machine platforms. Parameters originally developed on an ultra-high stiffness servo driven machine where first transferred to a high stiffness servo-hydraulic friction stir welding machine, and subsequently transferred to a purpose built machine designed to accommodate thin sheet aluminum welding. Weld parameters were developed to support high volume production of dissimilar thickness aluminum tailor welded blanks at speeds of 3 m/min and greater. Each was a commercially available, gantry style, multi-axis machine designed specifically for friction stir welding. Hovanski, Yuri Upadhyay, Piyush Carlson, Blair Szymanski, Robert Luzanski, Tom Marshall, Dustinĭevelopment and characterization of friction stir welded aluminum tailor welded blanks was successfully carried out on three separate machine platforms. The use of such coolants in the machining process is therefore recommendedįSW of Aluminum Tailor Welded Blanks across Machine PlatformsĮnergy Technology Data Exchange (ETDEWEB) The variation of the surface and near surface composition of samples machined either dry or with coolants was negligible after cleaning. While there was significant contamination left by the coolants, the cleaning process was capable of removing the residue. International Nuclear Information System (INIS)Īn x-ray photoemission spectroscopic study was undertaken to compare the cleaning of the Advanced Photon Source (APS) aluminum extrusion storage ring vacuum chambers after machining with and without water soluble coolants.
