Investigation 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 کاملFinite 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 کاملFormability Study of Steel Tailor laser Welded Blanks (TWB) in Stretch Forming
The use of TWB has been developed in automotive industries because of it’s advantages such as reduction in weight, cost and fuel economy of vehicles. The main objective of the peresent work is to study the effects of weld zone, diffrence in surface coating and thickness ratio on the formability of TWB composed of AISI 304, SPCC and IF steel sheets. It was found that the narrow weld zone has lit...

متن کاملinvestigation of forming limit and weld line movement in the forming of tailor welded blanks using experiment and numerical methods
the forming limit diagram (fld) is a useful method for characterizing the formability of sheet metals. in this paper, different numerical models were used to investigate the fld of tailor welded blank (twb). twbs were co2 laser-welded samples of interstitial-free (if) steel sheets with different thicknesses. the results of the numerical models were compared with the experimental fld as well as ...
