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...

Tailor Welded Blanks (TWBs) made of dissimilar, uniform or non uniform thickness materials have potential applications in automobile industries for light weight materials in order to improve fuel efficiency and cost of carrier. The focus of this paper is to develop and present analytical model to determine total elongation of tailor welded blank (TWBs). The validation of this method is done by ...

in this paper, the deep drawing process of tailor welded blanks is simulated using the finite element modelling and verified using the experimental results available in the literature. then the effect of die and material properties on the welding line movement is investigated. it is seen that the most effective material parameters on weld line movement are different between sheet metal thicknes...

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...

Currently, advances due to tailored blanking can be enhanced by the development of new grades of advanced high-strength steels (HSSs), for the further weight reduction and structural improvement of automotive components. In the present work, diode laser welds of three different grades of advanced high-strength dual-phase (DP) steel sheets (with tensile strengths of 980, 800, and 450 MPa) to hig...

use of tailor-welded blanks (twbs) in production has significant advantages such as weight and cost reduction. however, their application requires processes that increase their poor formability in comparison to base materials. one of these procedures is the use of fluid pressure in sheet metal forming. in this paper hydro-mechanical deep drawing process of tailor-welded low carbon steel (st12) ...

The automotive industry is constantly looking for innovative techniques to produce lighter, more efficient, and less polluting vehicles comply with the increasingly restrictive environmental regulations. One of latest technologies, which still developing, based on fabrication body-in-white car parts through stamping aluminum tailor welded blanks. Tailor blanks (TWBs) are generally a combination...

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...

Evaluation of welding process such as metal inert gas welding and tungsten inert gas arc welding on tensile, bend and hardness properties of austenitic stainless steel SS347H(18Cr 10Ni 1Cb ), T22(21⁄4Cr Mo) and T91(9Cr 1Mo V) grades are studied. Tubes of 54 mm of outer diameter and 4 mm of wall thickness is used as a base material in the following combination SS347H VS T91 and T91 VS T22 is wel...

ABSTRACT This paper refers to some numerical simulation and experimental tests related to forming and springback of a part manufactured from tailor welded blanks. Final shape of the formed part is seriously affected by springback effect. This paper work is trying to prove out the important role of welding line placement has on the springback phenomenon. The influence of the welding line placeme...
