Welcome
The automotive industry sector is a vital part of the European
economy. The EU is the largest automotive production region in
the world with 34% of global manufacture and the industry
comprises 7.5% of all manufacturing sectors within the Union.
The increasing demand for improved fuel efficiency and reduced
emissions at lower, competitive costs, have prompted the automotive
industry to seek ways of reducing the weight by using new light-
weight materials,new joining processes and new manufacturing concepts.
Due to pioneering work in the industry, the use of lasers for production
welding of Tailor-Welded Blanks (TWBs) and Body-In-White (BIW)
structures is now common practice. Current weld quality monitoring and
inspection techniques for these applications are often difficult in their application,
performed off-line, and are therefore time-consuming and expensive. Moreover,
current NDT inspection and tear-down, in which a fully assembled car is put through a
controlled crash, is only a sampling test, as not all parts can be inspected individually.
Because of the implications on the human and economic costs of the currently applied procedures,
major vehicle manufacturers would prefer to have an NDT record for each weld.
It is also the intention of performing this testing on-line, as 100% inspection using current off-line
procedures is economically not viable.
This pre-competitive project will develop a new, fast, monitoring and
NDT inspection system, the OLIWAM system, to be used on-line, providing a 100% inspection rate for thin-sheet laser
welded automotive components. The system’s software will allow for on-line evaluation of the results, with remedial
actions, if any, taken immediately, significantly reducing repair costs and scrap rates. Generic concepts for
up to a further four NDT inspection systems will also be developed to further facilitate fast, reliable on-line
detection of weld imperfections.
OLIWAM is a collaboration between the following organisations: TWI Ltd, Advanced Technology Group S.R.O., Computerised Information Technology, Microtest, NoError Enterprise, Precitec Optronik GmbH, Socomate, Tecnitest, Solblank, Volkwagen Group, AIMEN, NDT Consultants, Zenon SA.
