Coil Welds in Mill Finishing Lines (EMAT)

No items found.

The TEMATE SI-MWC and TEMATE SI-LC are designed for automated inspection of Mash Welds and Laser Welds used in annealing, galvanizing, recoiling and similar steel finishing lines. These TEMATE systems are the most reliable post-weld inspection system in the market, and the only one that can provide reliable volumetric inspection of the quality of the weld.


  • Non-contact EMAT technique.
  • Guided waves fill up the volume of the material and provide through-thickness inspection in one pass.
  • Detects partial and full disbond, porosity, inclusions, poor planishing, and weld skips.
  • 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.
  • Optional Process Monitoring hardware and software integrated with the weld inspection system.
