NON DESTRUCTIVE TESTING – NDT
To ensure high quality, and reliability in our weld overlay processes, we utilise a combination of non destructive testing techniques, and our highly qualified experienced technicians are approved to both national and international standards.
Subsequent to completion of all inspection processes IODS issue a final document of conformity including breakdown of methods, techniques and acceptance criteria, along with technical comments from qualified personnel.
DYE PENETRANT INSPECTION – DPI
All components are subjected to penetrant testing prior to overlay deposition and on completed items. State of the art remote video-probe inspection technology is utilised when inspecting internal bore diameters of pipe work. We are currently able to closely internally examine up to 12 meter lengths of pipe.
POSITIVE MATERIAL IDENTIFICATION
Positive material identification (PMI) is achieved using state of the art spectrometers, resulting in measurement of the most flexible working range of alloy metals, both ferrous and non-ferrous.
Individual components & weld deposition can be identified by chemical specification, the exact grade can be established from both unidentified samples and components of known analysis specification.
Reports can be downloaded from the spectrometers direct to PC for immediate analysis
Integrity of overlay bonding and base materials are closely examined by the use of ultrasound techniques, utilising a combination of shear and compression wave probes.
To ensure weld quality, IODS carry out thickness surveys to exacting customer standards.
MAGNETIC PARTICLE INSPECTION – M.P.I.
External surfaces of ferromagnetic components are examined for surface breaking defects after all manufacturing stages have been completed.
This can be done using either fluorescent or visible techniques.
CLAD THICKNESS INSPECTION
IODS use innovative equipment designed specifically for measuring cladding thickness of metallic protective linings such as Inconel on carbon steel and low alloy steel substrates.
