A Leading Global Company In The Field Of Welding Technology And Robotics

OTC DAIHEN Asia Co., Ltd.

OTC DAIHEN Asia Co., Ltd. was established in April 1989 as a strategic manufacturing hub for DAIHEN Corporation to serve the rapidly growing ASEAN market. Production began in 1990, leveraging Thailand’s strong supply chain and skilled workforce.

Initially focused on welding equipment assembly, the company has consistently evolved its technical capabilities and product portfolio. Following the 2011 Thailand flood, we significantly enhanced our operational resilience and modernized our facilities. Today, we serve as a key global production hub, supplying high-quality solutions to Japan, ASEAN, Europe, and Asia-Pacific markets across various industries, including automotive and heavy construction.
