AREVA NDT - Railway

Today’s Railway industry is faced with challenging issues surrounding NDT of wheel sets and axles. More stringent materials analysis requirements are moving the industry away from manual NDT to more automated processes offering efficiency, quality and repeatability. AREVA provides a full range of automated NDT systems to meet today’s requirements that are expandable to meet the challenges of tomorrow.

AREVA is a world leader in the energy industry with over 30 years of innovation, development, and commitment to success in advanced NDT solutions. AREVA’s knowledge and experience originated in the nuclear services industry, and for the last 15 years has expanded into other regulated NDT markets including railway, steel forging and aerospace.
