Center Studies Walloon of Assembly and Control of materials

CEWAC is a Walloon research centre performing services, studies and research for companies especially for SMEs.

It realises calculations, modelling, conception and design in the fields of welding and fluid mechanics. It offers consultancy and technical advice in these fields and in the field of vacuum and ultrahigh vacuum. It assists companies during the development of technological demonstrators and/or industrial prototypes and up to the realisation of pilot lots. Among the other services, we can mention quality controls, guidance on welding procedures and welder qualifications, conception and realisation of test stands for customized tests (and associated procedures), technology audits and  expert’s reports.

Its three laboratories develop many activities and most of their tests are covered by the ISO 17025 accreditation.
