2. Plastic weld non-destructive examination - Wikipedia

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

   Examples include joint mismatch, cracks, porosity, voids, inclusions, lack of penetration and lack of fusion (cold joints). However, the lack of defects does not necessarily mean the weld is adequate and thus NDE does not provide a good indication of weld strength, long term performance, or its ability to handle cyclic loading.

3. Nondestructive testing - Wikipedia

   en.wikipedia.org/wiki/Nondestructive_testing

   NDT is used in a variety of settings that covers a wide range of industrial activity, with new NDT methods and applications, being continuously developed. Nondestructive testing methods are routinely applied in industries where a failure of a component would cause significant hazard or economic loss, such as in transportation, pressure vessels ...

4. Weld quality assurance - Wikipedia

   en.wikipedia.org/wiki/Weld_quality_assurance

   Methods of weld testing and analysis are used to assure the quality and correctness of the weld after it is completed. 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.

5. Welding Procedure Specification - Wikipedia

   en.wikipedia.org/wiki/Welding_Procedure...

   The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.

6. Magnetic particle inspection - Wikipedia

   en.wikipedia.org/wiki/Magnetic_particle_inspection

   Examples of ferromagnetic materials include iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material.

7. List of welding processes - Wikipedia

   en.wikipedia.org/wiki/List_of_welding_processes

   This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

8. Plastic welding - Wikipedia

   en.wikipedia.org/wiki/Plastic_welding

   Hot gas welding, also known as hot air welding, is a plastic welding technique using heat.A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic.

9. Dye penetrant inspection - Wikipedia

   en.wikipedia.org/wiki/Dye_penetrant_inspection

   After excess penetrant has been removed, a white developer is applied to the sample. Several developer types are available, including: non-aqueous wet developer, dry powder, water-suspendable, and water-soluble. Choice of developer is governed by penetrant compatibility (one can't use water-soluble or -suspendable developer with water-washable ...
