Abstract
The increase in economic and technological competitiveness means that the automobile industry seeks constant innovation in its production methods and processes, in order to produce lighter, safer and more efficient vehicles. Products with greater mechanical resistance, better conformability, thickness combinations of plates / materials are sought with a focus on reducing mass and increasing the rigidity of the vehicle body. In this scenario, Tailor Welded Blank (TWB), which is a top welding technique (by unconventional processes) of sheets of different specifications (materials, thicknesses and / or coatings), appears as a solution, as it allows localized distribution of mechanical properties, mass, optimizing the relationship between structural rigidity and the total weight of the vehicle body. The great challenge of this technique is to combine two processes with completely different demands, welding and mechanical forming. Due to the complexity of forming TWBs, the use of simulations has been widely adopted. In this review, different results of the numerical simulation methods used for a Tailor Welded Blank are compared, focusing on the details and the influence of the parameters used.

Tailor Welded Blank (TWB) is the combination of two or more metal sheets joined through the welding process, as shown in FIG. 1.There is possible to, appears as a get a part with different materials, thicknesses, solution, as it allows localized distribution of mechanical mechanical properties and coatings
The development of TWB technique shown in figure 2, enabled application in several parts in the car body, what that made possible the increment of resistance and mechanical rigidity according to the need of the vehicle and the behavior of the added part [1,2,3,8]
Summary
By Wellington Augusto dos Santos, Etiene Pereira de Andrade, Guilherme Souza Assunção & Gilmar Cordeiro da Silva. Introduction are sought with a focus on reducing mass and increasing the rigidity of the vehicle body In this scenario, Tailor Welded Blank (TWB), which is a top welding technique (by unconventional processes) of sheets of different specifications. It is necessary to develop more processing time, as there are solid elements in the techniques that are experimental and analytical methods thickness that generate a model with many more to quantitatively assess the mechanical characteristics elements, which does not happen when we use the shell of the welded metal and the formability of TWBs. Effects elements [7,9]. Numerical Modeling Methods in Tailor Welded Blanks of welded metal, for example, must be taken into account [20]
