About Non Destructive Testing

Non Destructive Testing is a group of techniques and procedures used to investigate the properties of a component without altering or causing any damage to the material. This may be necessary to ensure continued compliance to given standards, for forensic examination or for scientific or research applications.

With over 3 decades of experience, Technical Inspection Services has the knowledge and expertise you need to ensure that your inspection is completed to the highest standards of compliance. We use a wide range of testing equipment, all of which is calibrated on a regular basis to ensure a maximum quality and accurate results. All of our capabilities can be carried out in house or on-site.

Radiography Examination

Radiography Examination

Performed in our controlled bays or onsite. Extreme safety measures do apply but we take care of all site safety and will normally carry out the inspection out of site hours. Our in house facilities include bay sizes up to 5 x 4 metres.

Ultrasonic Examination

Ultrasonic Examination

Ultrasonic Examination is a very practical way of checking the integrity of welds ≥8mm & parent materials ≥6mm. Thickness Checking is also ultrasonically based and can test thicknesses ≥2mm.

Magnetic Particle Inspection

Magnetic Particle Inspection

Magnetic Particle Inspection is a surface detection method for ferrous materials only. Including casting, forged and welded products. Fluorescent techniques can also be used, for intricate parts.


Portable Hardness Testing

Portable Hardness Testing

Portable hardness testing works on the Leeb (rebound) principle, a dynamic hardness test method based on velocity measurement: results are generated by the comparison between the impact speed and the rebound speed. Values can be produced in various hardness units including HRA, HRB and HRC, HB, HS and HV.

Liquid (Dye) Penetrant Inspection

Liquid (Dye) Penetrant Inspection

Liquid Penetrant Inspection (normally referred to as Dye Penetrant) is a surface detection method for ferrous and non ferrous materials. Including casting, forged and welded products. Fluorescent techniques can also be used, for intricate parts.

Visual Examination

Visual Examination

Visual Examination is a surface inspection technique. It can be used to measure joint set up before welding and after welding to measure weld geometry or even non-welded parts like castings and forgings. This inspection method requires no consumables.
