Tailor Welded Blanks
Tailor Welded Blanks
Rasandik Engineering Industries India specialises in Tailor Welded Blanks (TWB) technology. The company caters to the need of various automotive manufacturers and suppliers, and has set up TWB facilities at strategic locations across India. The TWB facilities of the company include Type LPQ3000 system, which produces laser welded tailored blanks. TWBs are produced by welding together two or more sheets of metal of different thickness, material grades, and/or coatings to produce a single blank, which is subsequently formed/stamped. Tailor blanks facilitate the production of components with integral reinforcements, optimally matched to the subsequent load. This enables component weight to be reduced whilst simultaneously enhancing rigidity, compared to conventional production methods. The forming of tailored blanks is almost identical to that of unwelded sheets. Tailored blanks are predominantly used as reinforcing components in the automotive industry such as the side members, pillars, door reinforcements-door inners and floor pans. Benefits of TWBs include reduced tooling costs, reduced lead time in product development, productivity increase in press shop, elimination of welded-on reinforcements and overlapping joints, improved resistance to corrosion behaviour, reduced spot welding/sealing, weight reduction as fewer parts and utilisation of different steel strengths is viable. One of the most prominent benefits is the reduction in vehicle weight.
