Tailor welded blank (TWB) is increasingly popular in producing sheet metal components especially for automotive industry. TWBs is employed by using dissimilar material welding which is mainly affected blank thickness and type of material used. This study is focused on the part thickness effects using experimental and numerical method. Thickness of tailor welded sheets plays an important role in sheet metal forming since fracture, wrinkling and weak spots are strongly influenced by material behaviour. In this study, simple heat transfer testing equipment is fabricated to conduct heat transfer experiment. A numerical and experimental study was carried out to investigate the heat transfer characteristic for different thickness of common used type of TWB material. The investigated thicknesses of aluminum 1100 are 1, 2 and 3 mm. Low heat capacity laser is used to measure the temperature distribution in experiment and used to validate FE model. A finite element model (2D) of aluminum 1100 is applied to simulate static heat distribution inside the material for different part thicknesses, heating position and amount of heat. The results shown that the heating region for thicker plate for combination 3 mm with 1 mm is 60 % wider compare to thinner plate with 40 %. Different combination of material thickness requires different heating positions and increasing the thickness of the material is increases the use of heat flux.

Focusing on techniques developed to evaluate the forming behaviour of tailor welded blanks (TWBs) in sheet metal manufacturing, this edited collection details compensation methods suited to mitigating the effects of springback. Making use of case studies and in-depth accounts of industry experience, this book gives a comprehensive overview of springback and provides essential solutions necessary to modern-day automotive engineers. Sheet metal forming is a major process within the automotive industry, with advancement of the technology including utilization of non-uniform sheet metal in order to produce light or strengthened body structures. This is critical in the reduction of vehicle weight in order to match increased consumer demand for better driving performance and improved fuel efficiency. Additionally, increasingly stringent international regulations regarding exhaust emissions require manufacturers to seek to lighten vehicles as much as possible. To aid engineers in optimizing lightweight designs, this comprehensive book covers topics by a variety of industry experts, including compensation by annealing, low-power welding, punch profile radius and tool-integrated springback measuring systems. It ends by looking at the future trends within the industry and the potential for further innovation within the field. This work will benefit car manufacturers and stamping plants that face springback issues within their production, particularly in the implementation of TWB production into existing facilities. It will also be of interest to students and researchers in automotive and aerospace engineering.

Tailor welded blanks are metallic sheets made from different strengths, materials, and/or thicknesses pre-welded together before forming into the final component geometry. By combining various sheets into a welded blank, engineers are able to ‘tailor’ the blank so that the properties are located precisely where they are needed and cost-effective, low weight components are produced. Tailor welded blanks for advanced manufacturing examines the manufacturing of tailor welded blanks and explores their current and potential future applications. Part one investigates processing and modelling issues in tailor welded blank manufacturing. Chapters discuss weld integrity, deformation during forming and the analytical and numerical simulation modelling of tailor welded blanks for advanced manufacturing. Part two looks at the current and potential future applications of tailor welded blanks. Chapters review tailor welded blanks of lightweight metals and of advanced high-strength steel and finally discuss the uses of tailor-welded blanks in the automotive and aerospace industries. With its distinguished editors and international team of expert contributors, Tailor welded blanks for advanced manufacturing proves an invaluable resource for metal fabricators, product designers, welders, welding companies, suppliers of welding machinery and anyone working in industries that use advanced materials such as in automotive and aerospace engineering. Engineers and academics involved in manufacturing and metallurgy may also find this book a useful reference. Examines the manufacturing of tailor welded blanks and explores their current and potential future applications Investigates processing and quality issues in tailor welded blank manufacturing including weld integrity and deformation Reviews both current and potential future applications of tailor welded blanks as well as specific applications in the automotive and aerospace industries

An approach to reduce manufacturing cost, weight, design and improve quality of a component is through the use of tailor welded blanks (TWBs). TWBs are welded blanks that consist of similar or dissimilar material, thicknesses, and surface properties before forming process. The purpose of the project is to evaluate the strength and fatigue behavior of the TWBs with different thickness combination and loading direction. The welding process was done by tungsten inert gas (TIG) arc welding. This study is divided into three parts. First, tensile tests were carried out. It was found that combinations were affected by the difference in thickness (2 mm/3 mm) and weld orientation (45o and 90o towards loading direction). The failure occurred in the middle of the weaker base metal parts. However, some of the joint specimens broke at the heat-affected zone. In addition, weld loading direction played a dominant role when the thickness difference was large. The second part investigates the effect of welding joint on the fatigue strength of the TWBs combination. The experimental results show that the failure occurs at welding zone as the specimens were subjected to fatigue and impact loading. In the last part of this thesis, the examination of the weld quality was carried out. Through the microstructure constituents in the weld, the strength and effects on the TWBs were discussed.

In the automotive and aerospace industries, the need for strong yet light materials has given rise to extensive research into aluminum and magnesium alloys and formable titanium alloys. All of these are categorized as light weight materials. The distinguishing feature of light weight materials is that they are low density, but they have a wide range of properties and, as a result, a wide range of applications. This book provides researchers and students with an overview of the recent advancements in light weight material processing, manufacturing and characterization. It contains chapters by eminent researchers on topics associated with light weight materials, including on the current buzzword “composite materials”. First, this book describes the current status of light weight materials. Then, it studies applications of these materials, given that, as the densities vary, so do the applications, ranging from automobiles and aviation to bio-mechatronics. This book will therefore serve as an excellent guide to this field.

The numerical simulation of sheet metal forming processes has become an indispensable tool for the design of components and their forming processes. This role was attained due to the huge impact in reducing time to market and the cost of developing new components in industries ranging from automotive to packing, as well as enabling an improved understanding of the deformation mechanisms and their interaction with process parameters. Despite being a consolidated tool, its potential for application continues to be discovered with the continuous need to simulate more complex processes, including the integration of the various processes involved in the production of a sheet metal component and the analysis of in-service behavior. The quest for more robust and sustainable processes has also changed its deterministic character into stochastic to be able to consider the scatter in mechanical properties induced by previous manufacturing processes. Faced with these challenges, this Special Issue presents scientific advances in the development of numerical tools that improve the prediction results for conventional forming process, enable the development of new forming processes, or contribute to the integration of several manufacturing processes, highlighting the growing multidisciplinary characteristic of this field.
