Seam-Tracking for Friction Stir Welded Lap Joints
This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...
متن کاملMicrostructure Evolution and Shaping of Friction Stir Lap Welded Dissimilar Magnesium Alloy Joint
Friction stir lap welding (FSLW) experiment has been conducted on 3mm thick AZ80 extruded sheet and 2.3mm thick AZ31B rolled sheet. The influence of the shape of the taper thread mixing head on microstructure has been discussed. Pores forming, hooked defects, interface migration, tissue distribution have been analyzed. The organization of both sides of nugget zone (NZ) is arranged diagonally ab...
متن کاملThe Strength of Friction Stir Welded and Friction Stir Processed Aluminium Alloys
Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...
متن کاملOn the Characteristics of Friction Stir Welding Lap Joint of Magnesium and Aluminum
Lap joints of commercially pure magnesium plates to aluminium plates (Magnesium plate on the top, and Aluminium plate, grade 1100, on the bottom side) were conducted by friction stir welding using various traveling and rotation speeds of the tool to investigate the effects of the welding parameters on the joint characteristics and strength. Defect-free lap joints were obtained in the welding tr...
متن کاملAutomatic seam-tracking of friction stir welded T-joints
In this research, a method for implementing automatic seam-tracking for friction stir welding, referred to hear as WeaveTrack, is presented. In this extrumum-seeking control technique, the tool weaves back and forth during welding to maintain the location where axial force is greatest, which is shown to be the center of the weld. Results demonstrate the effectiveness of this technique in tracki...
