Dye Penetrant Testing

Dye Penetrant testing, also known as Liquid Penetrant testing is a widely applied low-cost method used to locate surface-breaking defects on all non-porous materials. Even though it is one of the least complex methods to undertake, it is highly sensitive.

It uses simple equipment to detect flaws that are open to the surface and works on any material as long as it is not porous. The Penetrants are petroleum or water-based liquids coloured by a dye. Following the application to the surface, the liquid seeps into the open voids and then gets removed from the surface and replaced by a white developer. The developer acts as a blotter, drawing out the Penetrant trapped in voids. The Penetrant then stains the developer, indicating the presence and the location of the flaws/defects.

Dye Penetrant Testing is used for identifying different types of cracks such as fatigue cracks and hairline cracks as well as leaks and welding defects.

Ferrite Measurement

The amount of Ferrite in stainless steel weld metals can have an influence on a wide range of properties including corrosion resistance, toughness, long term high temperature stability, resistance to hot cracking etc. It is therefore essential for some applications that the ferrite level is controlled within specified limits and that methods are available for checking that specified levels have been achieved. If the ferrite content is too low, then the welded material is susceptible to hot cracking, if the ferrite content is too high, the toughness as well as the corrosion resistance of the steel is then reduced.

Hardness Testing

There are three types of tests used to ensure accuracy. The Brinell hardness test, Rockwell hardness test and the Vickers hardness test. The definitions of metallurgic ultimate strength and hardness are rather similar. It can generally be assumed that a strong metal is also a hard metal. How the three of these hardness tests measure the hardness of a metal is determined by the resistance of the metal to the penetration of a non-deformable ball or cone. The tests determine the depth at which such a ball or cone will sink into the metal, under a given load, within a specific period.
