Fabrication of synchronized hammer peening with pulsed laser welding and its effect on 6061 aluminum alloy weld
The non-continuous laser beam in pulsed lasers allows the mechanical peening between two consecutive beams on a still hot weld bead. At a very short time (20, 150 and 300 ms) after laser pulse application, mechanical peening was performed on the welding bead. To achieve these short times, the light sensor detects the nth laser pulse and the mechanical arm starts moving. Upon reaching the tip of...
متن کاملTwo-dimensional Mapping of Residual Strains in 6061-t6 Aluminum Alloy Friction Stir Welds
The residual strain profiles were measured through the thickness of friction-stir welded (FSW) plates using neutron diffraction to study the relationship between the angular distortion and the residual strain distribution. Three different weld specimens were prepared from a 6061-T6 aluminum alloy with the purpose of separating the effects of the frictional heat and plastic deformation on the re...

متن کاملThe effects of maintaining temperature in annealing heat treatment for an FSWed 6061-T6 Al alloy.
The technological development of all kinds of lightweight transportation devices including vehicles, aircraft, ships, etc. has progressed markedly with the demand for energy saving and environmental protection. Aluminum alloy is in the spotlight as it is a suitable environmentally friendly material. However, deformation is a major problem during the welding process because aluminum alloy has a ...
متن کاملComputational Kinetics Simulation of the Dissolution and Coarsening in the HAZ during Laser Welding of 6061-T6 Al-Alloy
-s 211 WELDING JOURNAL ABSTRACT. Laser beam welding (LBW) has become common practice in the production lines of several industrial sectors including the electronics, domestic appliances, and automotive industries. The advantages of LBW over conventional fusion welding processes (mainly GMAW and GTAW) is the lower welding heat input and smaller weld pool and HAZ dimensions, which are associated ...
