Finite element analysis of tailor-welded blanks
A typical tailor-welded blank (TWB) is composed of several base metals, which might have di!erent mechanical properties as well as thickness. Moreover, a TWB contains a heat-a!ected zone (HAZ) which has quite di!erent mechanical properties from base materials. The forming behaviors of TWBs have been widely studied since they were "rst developed as a way of using collectible o!al. They are often...
متن کاملSuperplastically Formed Friction Stir Welded Tailored Aluminum and Titanium Blanks for Aerospace Applications
The purpose of this study was to develop a specialized Friction Stir Welding process for superplastic grade aluminum alloy 5083-SP and titanium alloy 6Al-4V, in thickness of 1.5 to 4 mm, such that the butt welded nugget would have equal superplastic forming (SPF) characteristics as the parent sheet material The concept of using tailored blanks for the SPF process is proposed which will allow th...
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 کاملInvestigation on Formability of Tailor-Welded Blanks in Incremental Forming
Steel laser tailor-welded blanks (TWBs) are produced by end-to-end joining of base sheets using different welding methods. In this article, the formability of laser TWBs of St12 and St14 with thicknesses of 1 mm and 1.5 in single point incremental forming process were experimentally and numerically investigated. First, the forming limit wall angle was experimentally determined for each of the b...
متن کاملEffect 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...
