Non-Parallel

Non-parallel scan

A non-parallel scan is a scan that is done along the weld. The direction of the scan is non-parallel to the direction of the beam.

  1. The scanner is moved along the weld creating a B-Scan

Non-parallel scans can be done at high speed and are very good for detection purposes and initial sizing.
