INLINE IMAGING INFRARED I3LASWELD

I3LASWELD

On line Infrared Imaging system for assessing in real time the quality of laser welding processes

  • The I3LASWELD system for the inline quality control of laser welding processes, capable of detecting defects in weld seams in real time and identifying defective parts.
  • I3LASWELD provides high defects detection rates above 97%
Imaging infrared system for real-time laser welding process quality assurance

Defects

  • False friends
  • Lack of penetration / lack of fusion
  • Cracks, pores
  • Underfilling

Main characteristics

  • Easy adaptation to standard laser welding heads using C-mount optical interface
  • The classifier needs initial training
  • Real-time defect detection during the welding process
  • On-axis process observation using high-speed infrared imaging sensor (1 kHz)

I3LASWELD – News

  • Characteristics and performance of I3LASWELD system

New Infrared Technologies (NIT), in collaboration with the AIMEN Centro Tecnológico, has developed the I3LASWELD system for the inline quality control of laser welding processes, capable of detecting defects in weld seams in real time and identifying defective parts.

The I3LASWELD system (Inline Infrared Imaging Laser Welding QA) is based on a high speed infrared camera (1 kHz) manufactured by NIT, opto-mechanically coupled to the laser optics, which continuously monitors the geometry of the melt-pool.
