DUOMO is doing a constant effort to offer our customers products and services with the highest quality and adapted to their necessities. During the most recent years, DUOMO has had an interesting international growth following our customers’ requirements and adapting our procedures to meet the standards and specifications required in each market. Following this line, recently DUOMO joined the AWS (American Welding Society), as supporting company member, which allows us to work - worldwide - under the American Welding Standards and have direct access to the support and the information that allows our company to be up to date. Right now we have welders certified under AWS D1.1, D1.2, D1.3 and D1.6  and one of our technicians will be certified as  CWI in the following weeks.
