IUNA AI Weld Inspector - AI-powered weld inspection

Automated weld seam inspection with AI

Fully automatic visual inspection of weld seams

Ensure the highest weld quality – based on international standards

Our system enables the visual inspection of weld seams in accordance with globally recognized welding standards:

  • ISO 5817: Defines quality levels and acceptance criteria for weld imperfections in steel, stainless steel, titanium, and nickel.
  • ISO 10042: Applies specifically to aluminum welds and sets limits for acceptable deviations in aluminum arc welding.
  • ISO 6520-1: Serves as the classification basis for all welding imperfections and defines the types and categories of weld seam irregularities.

These standards ensure an objective, repeatable, and traceable assessment of weld quality across all production batches.

Weld Testing

With the IUNA AI Weld Inspector you can automate various testing and inspection steps:

  • Is the weld seam there?
  • Is the weld seam within the predefined tolerance range?
  • Automatic detection of irregularities in the weld seam
  • Automatic detection of cracks, pores, open end crater blowholes, burn-through, spatter, excessive asymmetry in the fillet and other defects that can be expected in normal production

Precise AI Analysis

Our AI-powered system precisely analyzes each weld seam, identifying the tolerance range and performing detailed segmentation. The IUNA AI Weld Inspector can detect even the smallest defects that might be invisible to the human eye.

The system automatically determines whether a weld seam is within the acceptable tolerance range and highlights any areas that require attention. This ensures consistent quality control and reduces the risk of defective parts reaching the next production stage.

  • Precise tolerance measurement
  • Advanced segmentation algorithms
  • Real-time defect detection

Advantages of Automated Visual Weld Seam Inspection

See why leading manufacturers choose the IUNA AI Weld Inspector over laser-based and ultrasound systems

Lightning Fast

Image Capture in Less Than 0.5 Seconds

The AI Weld Inspector flies over the seam (or the part moves past the camera), and the result is available immediately. We don't slow down your production line - we keep pace with it.

Our proven implementation process ensures a smooth integration

Our proven implementation process ensures a smooth integration of the IUNA AI Weld Inspector into your production environment:

1

Evaluation of Use Case

Contact us. Together, we will check your use case and the implementation options. After that we will select the required hardware components.

2

System Installation

We integrate all required hardware into your production process: industrial camera, IUNA AI Server, PLC, lighting system, and if necessary an inspection cell. We also install and configure our AI vision software.

3

AI Model Teaching & Configuration

The first image data is used to teach the AI inspection software. Even a small amount of images is sufficient for this.

4

Autonomous Inspection

From now on, the IUNA AI Weld Inspector takes over your inspection fully automatically. With the help of advanced AI vision models, you achieve consistent, objective quality control that is far superior to manual inspection.
