Laser welding seam tracking / joint gap adaptive control
LEXA Seam Tracking / Joint Gap Adaptive Control
While seam tracking the unwelded line, the gap width is also measured simultaneously, and adaptive control is performed with optimal welding conditions based on the measured gap width.
Laser Welding Seam Tracking 【Features】 ■ Significantly reduces the management of deviations from the welding line. Effective for laser welding of long, large components. ■ Capable of following changes in the welding line of components due to thermal deformation during welding. Laser Welding Joint Gap Adaptive Control 【Features】 ■ Performs adaptive control of "welding wire," "laser output," and "welding speed" in response to the gap in the joint, maintaining optimal parameters at all times. ■ Seam tracking can be used simultaneously. *For more details, please download the PDF or contact us.*

Applications/Examples of results
【Examples of Seam Tracking Achievements】 Long-length materials, large components This is a seam tracking system that continuously recognizes the un-welded line using a camera and automatically follows the un-welded line. If position correction of the laser beam is necessary, the laser welding processing head is directly moved by a drive mechanism to perform the position correction of the laser beam. As a result, the laser beam is always perpendicular to the un-welded line, preventing fusion defects from occurring from the surface to the back of the weld joint. 【Examples of Joint Gap Adaptive Control Achievements】 Long-length materials, large components While tracking the un-welded line, this system simultaneously measures the gap width and adapts the welding conditions to the optimal settings based on the measured gap width. It is a system capable of individually variable control and simultaneous variable control of three parameters: the feeding speed of the welding wire, laser output, and welding speed.

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.
