Tailor Welded Blanks

TEMATE SI-WB is the industry standard for automated inspection of laser welds in Tailor Welded Blanks. TEMATE SI-WB can be integrated on any line using the line conveyor, de-stacking robots or automated and manual scanners from Innerspec or other vendors.


  • Non-contact EMAT technique.
  • Guided waves fill up the volume of the material and provide thru thickness inspection in one pass.
  • Detects and discriminates “planar” defects such as lack of fusion, lack of penetration, concavity or mismatch, and “point” defects such as holes and porosity.
  • Insensitive to cosmetic defects that do not affect the structural quality of the weld. No false positives, typical of vision systems.
  • Less sensitive to probe positioning, no “rastering” motion or “phased array” of sensors necessary. Self-calibrated sensor. No need for teaching period or regular calibrations. Permits inspection at up to 1m/s in completely automated environments.
  • Exclusive flexible sensor technology that conforms to the surface and undulations of the part.
  • Multi-sensor capabilities with one system controlling up to three sensor heads.
  • Most proven and reliable system in the market with hundreds of systems installed.
