Weld and solder seam testing

Contactless, precise and fully automated.

With our active thermography, you can reliably identify defects in welded and soldered connections — non-destructive and inline capable.

How it works — explained in a nutshell

During the inspection of welded and soldered joints, the seam area is selectively thermally excited – for example, by laser or induction. Defects such as cracks, inclusions, or incomplete fusion disrupt the heat flow within the material. These thermal anomalies are detected by an infrared camera and analyzed via softwarenon-destructively, objectively, and in real time.

What is inspected?

Our thermography systems reliably detect:

  • Cracks & microcracks in weld seams
  • Pores, voids, inclusions
  • Lack of fusion & bonding defects
  • Defects in solder joints
  • Incomplete weld penetration
  • Seam position / alignment

Typical joint types:

  • Laser welds
  • Resistance spot welds
  • MIG/MAG welds
  • Brazed joints
  • Hybrid joints (e.g., CFRP–metal)

Application areas:

  • Body-in-white / car body construction
  • Battery housings
  • Structural frames
  • Axle components
  • Heat exchangers
  • Piping systems

Thermographic solution

Active thermography offers an efficient alternative to conventional inspection methods.
By applying targeted thermal excitation to the test area and analyzing the heat distribution, defects can be quickly and reliably identified.

A thermal pulse – generated using laser or induction thermography – is applied to the weld or solder joint.
Defects disrupt the heat flow, leading to local temperature variations that are captured by an infrared camera and analyzed via software.
