Quality Assurance plays a crucial role in the fabrication and manufacture of structures. Producers must ensure the delivery of high quality goods to their customers, which often ultimately exist in public environments. Such fabrications are produced to strict specifications and the structural welds used in creating finished goods must be inspected using Non Destructive Testing methods. Weld inspection is a primary NDT application.
Sonatest Flaw Detectors such as the Sitescan range contain a range of software features to assist with interpretation of ultrasonic echoes from welds, as well as evaluation tools such as DAC, AVG/DGS, AWS D1.1, API 5UE to comply with a number of different inspection standards.
Phased array ultrasonic inspection, using the Veo 16:64, this essentially replicates the principle of a standard ultrasonic inspection, but by using electronic rather than physical scanning over the weld volume, achieves a much faster inspection rate.
Dye-Penetrant or MPI is used on many parts, particularly where geometric considerations or thin sections make other techniques difficult. Penetrant is a surface technique: it can only detect defects such as cracking or porosity which are open to the surface.
For basic thickness measurement of components a thickness gauge from T-Gage IV series is ideal. Paint and coating thicknesses can be controlled using a gauge from the Sonacoat range.
These flaw detector sets are of a very rugged construction, we have used them for many years in foundries, fabrication shops, steelworks, refineries etc. without problems.
