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. The TEMATE SI-WB system can be complemented with OPTEMATE, a laser camera system designed to be integrated seamlessly within the TEMATE platform.
Features
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.
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 two sensor heads.
Most proven and reliable system in the market with hundreds of systems installed.
Optional camera system for measurement of lateral offset (a.k.a blank misalignment), excess weld metal, and positive mismatch.
