[ 1 ] - Influence of gas tungsten arc welding parameters on the formability of aluminum tailor welded blanks
Welding method and its parameters has an important effect on the formability and mechanical properties of tailor welded blanks(TWBs). In this study gas tungsten arc welding(GTAW) is used to joint aluminum TWBs. Aluminum TWBs consist of 6061 aluminum sheets with different thickness of 1mm and 2mm. Main parameters of GTAW consist of welding current, pressure of shielding gas, welding speed and di...
[ 2 ] - A Novel Approach for Formability Prediction of Tailor Welded Blank
Formability of Tailor Welded Blank (TWB) is an important parameter which limits this kind of blanks usage. A forming criterion for tailor welded blank is presented based on the analytical model in this research. This criterion suggests Limit Strength Ratio (LSR) and Limit Thickness Ratio (LTR) for forming limit of TWB. When thickness ratio or strength ratio in tailor welded blank is greater tha...
[ 3 ] - Effect of friction stir welding parameters on the ultimate tensile strength of Al-Cu tailor welded blanks
In the present study, parameters of tool rotation speed, tool travel speed and tool offsetting with different levels were used in the friction stir welding (FSW) of aluminum-copper tailor welded blanks (TWBs). The FSW of pure copper to 5052 aluminum alloy were carried out by varying tool rotation speed from 800 rpm to 1200 rpm, tool travel speed from 40 mm/min to 80 mm/min and tool offsetting f...
