New Fiber Laser Welding Machine
KIKUKAWA Installed New Fiber Laser Welding Machine
Boosting Competitiveness through Enhanced Welding Quality and Productivity
Kikukawa Kogyo Co., Ltd. (KIKUKAWA), specialized in interior and exterior architectural metalworks, is pleased to announce the installation of a new fiber laser welding machine at its factory and the official commencement of its operation after a safety prayer ceremony held on October 10, 2025.
The new laser welder is a robot-arm-type system capable of high-quality, deep-penetration welding even during high-speed operations. It reduces the need for post-processing and the time required for robot programming. With the improved welding quality and productivity, it is expected to cut the total man-hours for laser welding by 55% compared to conventional systems.
■Overview of the New Laser Welding Machine
Model: AMADA Fiber Laser Welding System FLW-6000ENSISe
Specifications: 6kW rated laser output, processing area W1,400 mm × L7,000 mm × H1,600 mm
Key Features:
High Quality and Stability: Advanced laser beam control ensures authentic finish of welds and stable penetration depth, even during high-speed welding.
Offline Teaching Function*: CAD-based offline teaching function significantly reduces the time required for robot motion programming.
Large Scale Capability: The travel carriage stroke has been extended to 6 meters (1.5 times longer than the previous model), and the processing room opening has been raised to 3-meter high to allow forklift access, enabling the handling of long and oversized products.
*Offline teaching: A programming method that creates and simulates robot motions using data, without stopping production lines.
■Background
KIKUKAWA has long utilized fiber laser welding system for its ability to realize low-distortion, high-strength welds on complex 3D shapes and long components. In fact, our previous system, installed in 2015, had been used in various projects.
As demand for highly designed decorative architectural material continues to grow, the processing capabilities of our previous equipment, after nearly a decade of operation, reached its limit. To meet the evolving needs, KIKUKAWA applied and was granted for “Capital Investment Support Subsidy” to introduce this new machine which is expected to further improve welding quality and productivity.
■Future Outlook
With this introduction, KIKUKAWA now operates three fiber laser welding machines—two robotic-arm types (including this new system) and one handheld type. By building a production system that leverages the strengths of each machine, KIKUKAWA aims to strengthen its competitive edge and further enhance customer satisfaction.
