Paper Title:

A Study of Flexible Roll Forming of Automotive Structures

Abstract: Roll forming is a continuous profile production process to form sheet metal progressively into desired shape with closer tolerances. The process offers several advantages such as complex geometrical shapes, high strength, dimensional accuracy, closer tolerances, and good surface finish. Several parts in automobile body are produced with this process. Conventional roll forming is limited to components with uniform cross-sections; the recently developed flexible roll forming (FRF) process can be used to form components which vary in both width and depth. It has been suggested that this process can be used to manufacture automotive components from UHSS which has limited tensile elongation. In this method, the pre-cut blank is fed through a set of rolls; some rolls are computer-numerically controlled to follow the three dimensional contours of the part and hence parts with variable cross-section can be produced.Several Parts in automobile body are produced with this process. Flexible roll forming process can easily be implemented to current production lines and synchronized with other stamping units. The pipe-shaped thin-walled cross-sections and complex shaped profiles which are difficult to produce by other methods can be produced by roll forming. Nowadays flexible roll forming technology draws more attentions than before in automotive industry.

Paper Title:

An General Review of Joining of Al and its Alloys by Fusion and Solid-State Welding Processes

Abstract: Among all the non-ferrous materials, aluminium is widely employed in various aerospace, defence and industrial applications. The natural qualities, of aluminium and its alloys, like lightness, electrical and thermal conductivity, corrosion resistance, suitability for surface treatments, the diversity of the alloys and intermediates, ease of use, recycling make them usable in many applications. The applications demand the manufacturing of components by a superior manufacturing process, so that the products will be without any defects. Welding is one such process which is widely used in fabrication of aluminium components. Both fusion and solid- state welding processes are employed in the manufacturing of aluminium components. An attempt is made in this paper to take an overview of some fusion welding and some solid-state welding processes to weld Al and its alloys with a focus on the process parameters of these processes, tools used, micro structure of the welded specimens, thermal profiles, strength of joints and heat treatment. This is an attempt understand and summarize the issues related to welding of aluminium and its alloys.
