- FY2026AdvancedAnnual report
「We had been studying and verifying the optimum welding conditions for applying automated welding technology to tank shell plates, and completed verification of the full range of welding methods and conditions during the current period. Going forward, we will put the technology into actual operation with the aim of improving the efficiency and quality of welding work in tank construction.」
For automated welding of tank shell plates, verification of the full range of welding methods and conditions has been completed, and a policy of moving to the actual-operation phase has been announced. - FY2025AdvancedAnnual report
「We began developing an autonomous visual-inspection robot for tank bottom-plate weld seams. In the next period, we will conduct field verification of the equipment produced and roll it out at worksites while making improvements.」
Tank technology is being expanded from automated welding to bottom-plate inspection robots, with demonstrations of application to vertical joints and field verification planned for the next period. - FY2024AdvancedAnnual report
「During the current period, we studied and tested welding conditions with the aim of expanding the application of automated welding for tank shell plates to vertical joints. We plan to continue this work, with the goals of establishing welding conditions for different plate thicknesses and securing consistent welding quality.」
Expansion of automated welding for tank shell plates to vertical joints and studies on application to low-temperature tanks are continuing. - FY2022AdvancedAnnual report
「Having accumulated sufficient experience and knowledge, we will expand the scope of applications and work to acquire more customers. We established a welding construction method that avoids risks and completed measures to comply with the Electricity Business Act, one of our targets, and will develop it as a repair technology of the Company.」
The scope of FREND Inspection was expanded, welding repair technology was established, and compliance with the Electricity Business Act was completed, advancing the practical application and rollout of value-added technologies. Drones were not introduced, and verification for outdoor flights and other applications is continuing. - FY2021AdvancedAnnual report
「To apply FREND Inspection™ to heat-exchanger tubes with U-bends, we began developing a sensor capable of passing through U-bends with small radii of curvature and obtained favorable results. In the next fiscal year, we will continue development with the aim of expanding the scope of application to heat-exchanger tubes of different designs. Regarding laser measurement, we conducted research into improving accuracy and equipment reliability, among other matters, and applied the results to actual operations.」
In addition to tank technology and 3D scanning, the scope of value-added technologies is expanding to include FREND Inspection for U-bends, the application of laser measurement to actual operations, and studies on the use of drones. - FY2020AdvancedAnnual report
「During the current period, the technology was applied to partial replacement work on the upper sections of tank shell plates arising from tank-opening inspection work. For 3D scanning technology, we can now obtain accurate base data for modification and renovation work in a short time, and the technology has been adopted at many sites.」
Field application of automated tank welding and adoption of 3D scanning at multiple sites are continuing. - FY2017AdvancedAnnual report
「After completing the research phase, we established the construction method and were able to move to field application. We can now obtain accurate base data for modification and renovation work in a short time, and the technology has been adopted at many sites.」
The construction method for applying automated welding equipment to tank shell plates was established, enabling field application, and 3D scanning technology was adopted at many sites. - FY2016First statedAnnual report
「We began research into modifying equipment to expand the application of the submerged arc welding machine previously used for welding tank bottom plates to tank shell plates. For the 3D-scanning technology whose introduction we had been pursuing, it became possible to obtain accurate base data for modification and repair work in a short time, and the technology has begun to be adopted at many sites.」
The company describes the expanded application of welding technology to strengthen its tank business and the adoption at sites of 3D scanning for modification and repair work.
