2. Plastic weld non-destructive examination - Wikipedia

   en.wikipedia.org/wiki/Plastic_weld_non...

   During laser welding, air bubbles can form and cause a degradation in the mechanical properties of the joint. Current inspection techniques are limited to finding air bubbles on the surface of the weld (optical and scanning electron microscopy). Destructive testing is usually required to find volumetric flaws.

3. Nondestructive testing - Wikipedia

   en.wikipedia.org/wiki/Nondestructive_testing

   Non-Destructive Testing (NDT/ NDT testing) Techniques or Methodologies allow the investigator to carry out examinations without invading the integrity of the engineering specimen under observation while providing an elaborate view of the surface and structural discontinuities and obstructions. The personnel carrying out these methodologies ...

4. Weld quality assurance - Wikipedia

   en.wikipedia.org/wiki/Weld_quality_assurance

   This term generally refers to testing and analysis focused on the quality and strength of the weld but may refer to technological actions to check for the presence, position, and extent of welds. [citation needed] These are divided into destructive and non-destructive methods. A few examples of destructive testing include macro etch testing ...

7. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   This is the basis of standard (pancake coil) ECT. NDT kits can be used in the eddy current testing process. [6] ECT has a very wide range of applications. Since ECT is electrical in nature, it is limited to conductive material. There are also physical limits to generating eddy currents and depth of penetration . [7]
