High-productivity laser processing (laser welding system) supporting verification, prototyping, and mass production
Laser welding machines (laser welding systems) require total solution capabilities that integrate a complex mixture of core technologies.
We combine advanced core technologies and equipment integration expertise to solve customer issues previously considered difficult.
This page provides a central introduction to some of our core technologies.

1. Configuration of High-productivity Laser Processing Machines (Laser Processing Systems)
Laser processing machines (laser welding systems) generally consist of the following hardware configuration. Since the considerations required for verification, prototyping, and mass production differ, we will propose the optimal solution for each customer's project.
- Laser oscillator: Oscillator body, cooling chiller, transformer, etc.
- Laser head: Welding head, fiber, camera, OCT, etc.
- Equipment: Jig, stage, measurement camera, displacement meter, etc.
- Equipment accessories: Dust collector, assist gas, etc.
2. Core Technologies That Comprise Laser Processing Systems
To address customer issues that were previously considered difficult, laser processing machines (laser welding systems) require advanced hardware and software. We would like to introduce some of our distinctive core technologies.
2-1. Optical Systems with Minimal Focus Shift That Suppress Thermal Lens Effects
Laser welding uses high-power laser beams, requiring measures to ensure stable mass production. A typical example is the prevention of focus shift in laser heads (optical heads). This is a measure against problems caused by the "thermal lens effect" in optical components, a phenomenon specific to high-power lasers.
Our laser heads (Scanning Heads) feature Panasonic's proprietary "optical systems with minimal focus shift," enabling stable mass production.
2-2. Panasonic's Proprietary Galvano-NC Coordinated Control Technology
Laser welding often requires equipment with higher productivity due to the high cost of laser oscillators and other components. When high productivity is required, we sometimes propose "galvano-NC coordinated control." This system enables continuous laser welding, unlike conventional intermittent welding (step-and-repeat actions), thereby achieving high productivity.
Our galvano-NC coordinated control has been used for laser welding systems based on the orthogonal coordinate system. In addition, this coordinated control has a track record of being used to build laser welding systems based on the polar coordinate system, as shown in the video, allowing us to offer a wide variety of proposals.
2-3. Versatile Monitoring Functions, Including Laser and Galvano Monitoring
Laser welding systems often require a wide range of monitoring functions. This is because these functions provide the following advantages during both verification and mass production.
We offer a wide variety of monitoring functions, primarily laser and galvano monitoring, and can provide a broad range of solutions.
- During verification: The galvano mirror speed and position as well as laser status can be visualized.
- During mass production: Various monitoring functions help prevent the outflow of defective products. (Traceability is also enabled.)
