Lap Welds (Mash Welds) in Steel Finishing Lines

The temate® SI-MWC is designed for automated inspection of Mash Welds used extensively in the manufacture of steel containers, appliances and the automobile industry. The temate SI-MWC is 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 thru 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.
