Three defect types in friction stir welding of aluminum die casting alloy
For different tool plunge downforces, the optimum FSW conditions of aluminum die casting alloy were examined. The higher the tool plunge downforce is, the wider the range of the optimum FSWExpand
Tensile properties and fracture locations of friction-stir-welded joints of 2017-T351 aluminum alloy
Abstract Friction stir welding (FSW) is a new and promising welding process that can produce low-cost and high-quality joints of heat-treatable aluminum alloys because it does not need consumableExpand
MWCNTs/AZ31 surface composites fabricated by friction stir processing
Abstract Multi-walled carbon nanotubes (MWCNTs) were successfully dispersed into a magnesium alloy (AZ31) using friction stir processing (FSP). Distribution of the MWCNTs was changed on the basis ofExpand
Effect of tool shape on mechanical properties and microstructure of friction stir welded aluminum alloys
Abstract Prospecting the optimal tool design for welding steels, the effect of the tool shape on the mechanical properties and microstructures of 5-mm thick welded aluminum plates was investigated.Expand
Wear characteristics of a WC–Co tool in friction stir welding of AC4A+30 vol%SiCp composite
Tool wear is a key issue for the friction stir welding (FSW) of aluminum matrix composites (AMCs), especially when the volume fraction of reinforcing particulates is relatively high. In this study, aExpand
Friction stir welding of a high carbon steel
A high carbon steel joint, S70C (0.72 wt.% C), was successfully friction stir welded without any pre- or post-heat treatment. There are two methods for obtaining proper joint properties. The firstExpand
New technique of self-refilling friction stir welding to repair keyhole
Abstract A new technique of self-refilling friction stir welding (SRFSW) relying on non-consumable joining tool has been developed to repair the keyhole left at the end of 316L stainless steelExpand
Flexible control of the microstructure and mechanical properties of friction stir welded Ti–6Al–4V joints
Abstract The effect of the thermal cycle during friction stir welding (FSW) on the microstructure and mechanical properties of a Ti–6Al–4V alloy joint was investigated by welding 2-mm-thick alloyExpand
Weld Penetration and Marangoni Convection with Oxide Fluxes in GTA Welding.
Active flux can modify the fusion zone geometry dramatically in GTA welding (A-TIG). In the present study, in order to investigate the effect of the active flux on the Marangoni convection in theExpand
Microstructure and mechanical properties of S45C steel prepared by laser-assisted friction stir welding
Abstract In this study, a laser heating system was used as a preheating source during the friction stir welding of 3.2 mm thick S45C steel plates. The position of the laser focal point exerted aExpand
