We have developed a jig-less arc welding process that eliminates the need for dedicated jigs in door frame production.
Our jig-less high-precision robotic technologies automate processes once difficult to automate and tasks reliant on operator skill, delivering major productivity improvements.
By delivering solutions optiized for each customer’s work environment, we help tackle the widespread societal challenge of labor shortages.

Challenges during the transition from mass production to service parts (small-lot, multi-variety production)
After mass production ends, production frequency and volume drop significantly. Continuing with conventional manufacturing methods leads to the following issues:

• Capacity of jig storage
• Labor cost for jig changeovers
• Labor cost for tool adjustment

To address these production challenges, we developed 'jig-less welding' by questioning the conventional approach of welding using traditional jigs.

Jig Storage

Labor cost for jig changeovers

Eliminating the need for changeovers with the jig-less method
