The "Welding Visualization System" synchronously plays back the waveform data of the welding machine's voltage and current values, which are recorded simultaneously using an analog waveform data collection device during shooting with the high-speed camera MEMRECAM, along with the high-speed camera footage on a computer. It allows for observation in a slow-motion image synchronized with the waveform, as well as quantitative analysis. The waveform data can be output as text and imported into Excel, and the high-speed camera used for shooting can be selected according to the application and site conditions. 【Features】 ■ Enables observation of arc behavior, molten pool, spatter, slag generation, solidification behavior, etc. ■ Synchronously collects and displays waveform data such as voltage/current ■ Waveform data can be output as text and imported into Excel ■ The high-speed camera used for shooting can be selected based on application and site conditions *For more details, please refer to the related links or feel free to contact us.

Temperature analysis of the welding molten pool can be performed by loading images obtained from a high-speed camera into the dedicated software "Thermias." Using image processing based on the two-color ratio method, it is possible to display and output results such as pseudo-color, temperature maps, line profiles, and time-series graphs for subjects within the temperature range of 700°C to 2,800°C. Additionally, by combining a black-and-white camera with a dedicated optical system (TM2S), it is possible to extract different wavelengths from a single sensor, allowing for temperature measurement across a wide range from low to high temperatures. 【Features】 ■ Temperature analysis is conducted by selecting any two wavelengths from RGB in welding images captured with a color camera. ■ Welding images captured using a combination of a black-and-white camera and the bifurcated optical system TM2S allow for the selection of two wavelengths freely, excluding the near-infrared region. *For more details, please refer to the related links or feel free to contact us.

"Weld-Judge" is a device that allows users to set parameters for three types of high brightness, spatter, and fumes, and perform real-time quality assessments. It consists of a specially developed processing board, software, control and development PC, and a camera (C-Cam) for capturing images. The camera is a compact, high-sensitivity type that can be mounted for coaxial shooting or on welding robots for capturing images. 【Features】 ■ Real-time assessment at 500Hz ■ Compact camera for easy coaxial setup and installation ■ Immediate quality assessment after welding, with the ability to save as video ■ Signal output based on each assessment ■ Feedback to processing machines is also possible *For more details, please refer to the related links or feel free to contact us.

The "MEMRECAM series" automatically tracks target points in high-speed recorded video files (video, still images, Raw) and allows for quantitative analysis of parameters such as speed, displacement, and area from the obtained coordinate data. By importing analog waveform data, synchronized display of waveforms, coordinates, and videos is possible, and this display can also be output as a video. Additionally, using two cameras enables three-dimensional analysis. 【Features】 ■ Tracking targets: AVI/WMV/TIFF/BMP/JPG/RAW (MCFF) ■ Tracking types: Marker automatic tracking (quadrant circles, bright points, dark points, etc.) ■ Physical quantity calculations: Displacement/Speed/Angle/Area, etc. ■ Import: Analog waveform data (up to 2MHz)/Coordinate data *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our "Combustion Spray Phenomenon Visualization and Analysis System." To confirm the safety of products, it is possible to observe the ignition timing of combustion and how flames spread when an object explodes. We also offer accessories suitable for high-speed imaging, such as the "Image Intensifier UVi," which is ideal for measuring specific wavelengths like radicals or capturing excitation luminescence phenomena. 【Optional Shooting Accessories Features】 ■ Image Intensifier UVi - Well-suited for measuring specific wavelengths like radicals or capturing excitation luminescence phenomena - Usable with both high-speed cameras and high-speed shutter cameras ■ Dual-Branch Optical System TM2S - An optical system that allows a single high-speed camera to capture two wavelengths *For more details, please refer to the related links or feel free to contact us.

It is possible to observe and analyze engine combustion and fuel injection using a high-speed camera. We have installed high-speed cameras to capture images through the windows of visualization engines and spray chambers, which have been made transparent with glass for observing certain metal parts. We offer temperature analysis software "Thermias," which calculates data using a two-color method and displays and outputs results as pseudo-color, temperature maps, line profiles, and time-series graphs. 【Features】 <Options and Shooting Accessories> ■ Bore scope optical system for in-cylinder visualization - An optical system with heat and pressure resistance designed to capture the spray and spray phenomena inside the combustion chamber of actual engines that cannot be directly visualized. ■ Image intensifier UVi - Suitable for measuring specific wavelengths such as radicals or capturing excitation luminescence phenomena. *For more details, please refer to the related links or feel free to contact us.
