Several welding companies, merged into one
Through its mergers and acquisitions, Automation International has shown unbroken continuity in the supply of arc and resistance welding machines and metalworking equipment for over 100 years.

Today
What the mergers mean for customers
Three well-known industrial machinery companies and two later acquisitions now sit in one Danville plant. That covers automated, flexible welding and forming systems from one machine to a complete production line.
It also means drawings, records and parts for the older machine lines are still available.
