The cross-sectional shape and 3D shape of the keyhole formed during laser welding can be measured.
"LEXA OCT" is a monitoring system that continuously monitors the keyhole cross-sectional shape during laser welding and provides immediate quality assessment. It is capable of acquiring the cross-sectional shape and 3D shape of the keyhole in the laser weld. Since there is a close relationship between the keyhole shape and welding quality, properly managing and utilizing this information leads to the maintenance of good welding quality and the early detection of welding defects. [Features] ■ Immediate quality assessment through continuous monitoring of the keyhole cross-sectional shape ■ Utilization of accumulated data to detect trends and early signs of quality issues ■ Management of keyhole depth and width is possible *For more details, please download the PDF or contact us.

Applications/Examples of results
【Application】 Real-time management of welding penetration depth and weld width By monitoring the keyhole cross-sectional shape and its 3D shape during laser welding, real-time management of "keyhole depth" and "keyhole width" is possible. 【Application】 Early detection of welding quality defects By understanding and utilizing the keyhole shape during good/bad welding, it is possible to detect early signs of welding quality defects. This enables timely predictive maintenance, leading to the continued maintenance of good welding quality.
Detailed information
-
By scanning the measurement laser, it is possible to obtain data on the depth distribution of the keyhole and visualize the cross-sectional shape of the keyhole.
-
The 3D graph arranged in chronological order of the obtained keyhole cross-sectional shape data can be observed from various angles, allowing for a detailed capture of the changes in the keyhole shape.
-
By scanning the measurement laser across the surface, it has become possible to measure the three-dimensional shape of the keyhole.

Company information
At Maeda Industries, we offer a diverse range of laser devices, various peripheral equipment, and analytical instruments to achieve high-precision laser methods. Additionally, by utilizing our self-developed monitoring system for laser welding, we can visualize, measure, and instantly assess the quality of the keyhole and molten pool. This capability allows us to provide experimental results as digital data to our customers during the development of laser welding methods. As a result, we can accurately grasp the technical basis of laser welding and clarify the direction our customers should take. This leads to a significant reduction in development time and a decrease in risks when introducing laser technology, providing substantial benefits to our customers. Furthermore, the digital data obtained during the in-process phase can be used for adaptive control during laser processing, continuously maintaining the optimization of processing conditions, which contributes to quality stability.
