Ultrasound weld testing (UWT) or ultrasonic testing emits high-frequency sound waves from a transducer into an object material analyzing returning waves to detect faults inside. Using multiple probes at different angles technicians can locate and size internal defects in welds and plate laminations or cracking.

Used to detect and identify flaws in a variety of manufactured materials a Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) method that uses magnetic particles and fields to inspect surfaces and sub-surfaces. MT is a surface inspection method used to aid the visual inspection of ferrous parts for surface-breaking defects.

Dye Penetrant (PT) is designed to aid the visual inspection of surface breaking flaws such as cracks, porosity, seams and other defects. Mostly used on stainless steel, aluminium, plastic etc.

New technology taking over from RT (Radiography), PAUT has a higher probability of detection than RT, its a lot faster & cost-effective, and eliminates the harmful radiation and exclusion zones so it's much safer. Welders can do repairs straight away and reinspection can be done instantly. Cancels out all the delays and safety requirements RT  requires.

ET can be used to detect near-surface defects without the need to remove the coating. Ideal for for various on-site and plant inspections. A common use is 10 yearly major inspections, gears, and components, bolts & threads & in-service assets.

Using high frequency to measure material thicknesses in all types of material at different velocities.

Visual is the most basic but most used inspection method. Defects and problems to assets can be detected by highly trained technicians before serious damage is done. Compliance inspection of mine site equipment, and all site assets.
