Weld surface profile and groove geometry measurement application plan

This solution focuses on geometric measurements of pre-weld grooves, root gaps, misaligned edges, cold weld reinforcements, weld legs and visible undercuts, and outputs results based on section and position.

Tasks and image input

Weld color and reflection changes will affect ordinary image judgment, and surface geometry requires an independent cross-section datum.

Input data: fringe diagram or calibration outline of cold standard groove/weld sample; coding position is required for inspection along the way. Weld slag, masking, and steep wall samples were retained.

Algorithm processing and output

Valid line segment association→surface/groove segmentation→angle, root gap, misalignment and weld section calculation→positioning or rejection along the way.

Output results: Bevel angle, root gap, offset edge, width, reinforcement, welding leg and visible undercut depth candidates.

Implementation and verification

First complete a cold geometry package for the groove/weld family, and then adapt the arc, thermal and robot interfaces as data becomes available.

Verification method: Use welding profile gauges, profilers or three-dimensional coordinates to compare item by item, isolate development and test sets according to workpieces; set up additional working conditions for arc light/thermal conditions.

Applicable boundaries and existing basis

Internal lack of fusion, porosity, penetration or strength is not judged; seam tracking and closed-loop weld control are not out-of-the-box features of this measurement solution.

There are limited public examples of line center extraction, and unknown scene full-image correlation, specific features, and real-machine calibration still need to be developed and verified.

Corresponding algorithm:Laser line extraction and cross-section geometry measurement algorithm;Laser line scanning topography and surface geometry analysis algorithm。

Industry public information reference

The following content is used to illustrate the systematic division of labor of similar tasks in public industry materials. The original project does not belong to Jishi Technology, and the original data parameters are not converted into the performance commitment of this page.

Third-party public information · Inrotech / Micro-Epsilon

Inrotech: Pre-weld contour scanning and automatic welding

According to Micro-Epsilon's public application data, Inrotech-Crawler uses scanCONTROL 2900 to collect the seam geometry before welding, and the calibrated contour enters Inrotech's software process through the interface.

References to this program:This case shows the division of labor between contour measurement, task software and welding control, and can be used as an industry reference for laser cross-section participation in equipment processes.

Reference boundaries:We have no delivery record of the equipment or Weldlogic, and cannot transfer its control capabilities, applicable working conditions and performance into our indicators.
