“…One method of weight reduction is to replace steel with lighter materials such as aluminum or magnesium alloys [3]. Recently, in order to save material and maximize weight reduction, tailor-welded blanks (TWBs) of aluminum alloys have been tested for producing vehicle body panels with stamping processes [4][5][6]. However, there have been several difficulties in the development of aluminum TWBs with conventional fusion welding methods such as laser welding owing to the occurrence of hot cracking and the inherent oxide layer [6].…”

However, there have been several difficulties in the development of aluminum TWBs with conventional fusion welding methods such as laser welding owing to the occurrence of hot cracking and the inherent oxide layer [6]. Therefore, friction stir welding (FSW), a solidstate metal joining technology, has been used to produce aluminum TWBs in recent years because it offers various advantages in comparison to conventional fusion welding techniques.…”

The purpose of this study is to improve the mechanical properties and formability of friction stir welded tailor-welded blanks (TWBs) of Al6061 alloy with a new forming method called hot forming quenching (HFQ) in which solid-solution heat-treated aluminum sheets are formed at elevated temperature. Forming and quenching during HFQ are simultaneously performed with the forming die for the solid-solution heat-treated sheet. In this study, specimens of aluminum TWBs were prepared by friction stir welding (FSW) with a butt joint. The effectiveness of FSW joining was evaluated by observation of the macrostructure for different sheet thicknesses. In order to evaluate the formability of TWBs by HFQ, a hemisphere dome stretching test of the limit dome height achieved without specimen failure was performed with various tool temperatures. A Vickers test was also performed to measure weldment hardness as a function of position. The formability and mechanical properties of products formed by HFQ are compared with those formed by conventional forming methods, demonstrating the suitability of HFQ for sheet metal forming of friction stir welded TWBs.

“…Many applications such as aerospace, automotive and ship building industries, [1] widely use the friction stir welding to weld the lightweight materials, such as aluminum, magnesium and titanium. More effective welding and joining techniques are essential, however for further usage of magnesium alloys.…”
