Significantly improving inspection accuracy and efficiency with AI welding spot inspection.

Conventional welding spot inspections have been conducted using visual confirmation, distance measurements, and contact measuring devices. However, these methods have faced challenges such as long measurement times, variability in results due to the operator, and low detection rates when the indentations are small. Particularly, when the shape reproducibility of 3D scanners is low, automatic detection can become difficult. The "AI Welding Spot Inspection" feature addresses these challenges, enabling simpler and more precise welding spot inspections. By analyzing the curvature gradient images projected onto the weld marks, AI reduces measurement time, improves detection accuracy, and eliminates variability in results caused by human operators, significantly contributing to the efficiency and reliability of welding quality management. **Features of spGauge AI Welding Spot Inspection:** - Achieves a high automatic detection rate even when the indentations of the weld marks are small or when the shape reproducibility of the 3D scanner is low. - Significantly reduces false detections compared to conventional inspection functions. - Supports a series of tasks including automatic pairing with 3D measurement data, automatic detection of positional deviations, and report generation. *For more details, please refer to the page below or feel free to contact us.*

basic information

The "spGauge" is a tool that can quickly detect abnormal areas in product shapes and mold shapes by comparing point cloud data output from a non-contact measurement device that can measure a wide range quickly with 3D CAD data. It supports alignment methods using the entire shape or parts, as well as alignment using reference points (such as planes, lines, and hole positions). This allows users to select the appropriate alignment method based on the inspection target and purpose, enabling them to obtain high-precision inspection results. 【Alignment (Excerpt)】 ■ Alignment at reference points ■ Alignment in cross-sections ■ Touch alignment ■ Alignment that matches corresponding surfaces 【Inspection (Excerpt)】 ■ Error gradation inspection ■ Dimensional tolerances and geometric tolerances ■ Cross-section inspection ■ Distortion detection ■ Specialized functions for cast and resin products ■ Specialized functions for pressed products *For more details, please download the PDF or feel free to contact us.
