How can computer vision help a fabrication shop check welds for visible defects?

# How can computer vision help a fabrication shop check welds for visible defects?

Cameras at a weld station or a phone photo routine can capture each finished weld under consistent light. A computer vision model trained on your own good and rejected welds can flag visible surface issues such as porosity, cracks, undercut, spatter or welds that look too short or off position, and attach the marked-up photo to the part record. It only sees what is visible on the surface, so it supports your inspection plan rather than replacing it. A qualified inspector reviews every flag and makes the accept or reject decision, and any testing your work requires still happens as usual.

## What this means in practice

- Set up consistent lighting and camera angles at each weld station.
- Collect and label photos of good welds and of each defect type your inspectors reject.
- Train or tune a model on those photos and test it against inspector decisions.
- Have the model flag visible issues and attach photos to the part record.
- A qualified inspector reviews every flag and makes the final accept or reject call.

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
