OTC DAIHEN designs, builds and installs robotic and manual welding systems, with arc-welding robots at the center of its work. The U.S. operation traces its roots to 1979 and moved its headquarters to Ohio after establishing a Dynamic Robotic Division there in 1996. Drawing on a company history that began in Japan in 1919, OTC DAIHEN supports customers with training, service and parts as well as integrated welding automation.
