Deep Learning in Weld Inspection

On Demand Until April 15, 2022

Duration:30 minutes


When it comes to spot welding, electrical testing will catch some failure conditions, but is insufficient by itself. Visual inspection is challenging and often not done because of the unpredictable variations in both good part and bad part appearance.

Deep learning addresses two key issues.  This information can be dynamically fed to a process control system that can trigger a corrective action process

During this webinar, we'll dive into deep learning and how it can help:
  • Differentiate between good and bad parts allowing for 100% automated visual inspection dramatically reducing production of defective components
  • Classify the type of defect of bad parts which can then be fed into a process control system triggering corrective action processes
  • Achieve a level of consistency and cost effectiveness that's not possible to achieve through manually inspection
