ARO celebrates 70 Year anniversary

ARO marks its 70th year in resistance welding technologies.

Established in 1949 by Albert Roland in Paris, ARO initially supplied welding equipment to the motor body repair sector.

During the 1950’s manual welding guns and stationary machines were developed for diverse industry applications.

In 1957, ARO expanded and built its new production site in Chateau du Loir, which today is the home of the ARO headquarters and main manufacturing site.

A range of robotic welding guns was launched in the 1980’s and by the 1990’s ARO was supplying many of the world’s automotive giants. Today with global subsidiaries and a network of partners worldwide, ARO is a leading force in its field with new products and ground breaking technologies.

“We are very proud of the role ARO has played in resistance welding” says Jean-Yves David, President of ARO Technologies. “As well as taking a trip down memory lane, today we continue to focus on our commitment to our customers solving new and complex welding applications; this has been at the heart of our long-term success.”.
