Detection of Internal Welding Flaws

Matrix Phased Array Inspection System

Detects planar internal welding defects of thick materials with high sensitivity!

Solution Point

  • Also possible to detect planar defects, which were difficult to detect by the conventional tandem probe technique.
  • Possible to shorten the detection process by applying a phased array beam.

Features 01

Expected Problems
?Don't you have trouble detecting internal planar welding defects using the tandem probe technique?
?Aren't missed defects a problem?
?Doesn't adjustment of the measurement position require too much time?

Features 02

Technology highlight
?Independent development of a probe and wedge suitable for the phased array method.
?Possible to detect planar defects with high sensitivity while also suppressing the effect of welding geometry by using a combination of the phased array beam and normal incidence method.
?Possible to reduce the number of sensor movements required for flaw detection by digital beam scanning.

*Possible to perform quality checks immediately after welding.

Features 03

Proposed Solutions (Examples)
?Supply of an integrated inspection system to an existing production line where inspection of welds of thick products was required.
?Also possible to supply only the detection probe (using a commercial signal transmitter/receiver that satisfies the required specifications).
