Joint Inspection

The quality of joints is essential for the strength, functionality and reliability of components. Defective adhesive bonds, soldered joints or other connections can compromise mechanical performance and electrical functionality. FOERSTER provides non-destructive inspection solutions to detect irregularities in joints and help manufacturers ensure consistent product quality.

Joints are used in a wide range of industrial applications, from mechanically loaded components to electrical connections. During manufacturing, defects such as insufficient adhesion, poor bonding, porosity, inclusions or cracks may occur. Particularly in adhesive and soldered joints, as well as electrical connections involving battery cells, cell connectors and busbars, such defects can compromise joint integrity and long-term performance. Since critical discontinuities often remain hidden beneath the surface, reliable non-destructive inspection is essential.

FOERSTER offers inspection solutions for various joint types and component geometries. Depending on the material, joining method and inspection requirements, different active thermography technologies can be applied. Controlled thermal excitation and the analysis of heat propagation reveal changes in thermal behavior that may indicate defects or insufficient bonding. Methods such as laser thermography and optically excited lock-in thermography enable application-specific inspection of joining areas, adhesive bonds and electrical contact points. These technologies support quality assurance applications as well as integration into automated manufacturing processes.

With extensive expertise in non-destructive testing, FOERSTER supports manufacturers in the early detection of critical joint defects. Reliable inspection results enable targeted quality control, reduce the risk of defective components and support stable, efficient production processes. Joint inspection therefore contributes to consistent product quality and long-term operational reliability.
