Radiography is a well-established technique that is widely used to detect internal flaws in welds and castings and to check for mis-construction in assemblies.
This method can find most manufacturing flaws (lack of sidewall fusion, lack of root fusion, lack of root penetration, porosity, solidification cracking, etc.) and in-service flaws (fatigue cracking,
If applied correctly, liquid penetrant testing offers a fast, cheap and relatively simple means of surface inspection, making it attractive to a number of industries. - Currently, TTA has been applyin
MT is used to detect surface-breaking and sub-surface flaws in ferromagnetic materials. It cannot, however, be used to detect deeply embedded flaws, nor can it be used on non-ferromagnetic materials,
There are 2 quasi-static hardness testing according to the UCI method and dynamic hardness testing according to the rebound method.
To test on site the hardness of the parts after being heat treate
Positive Material Identification (PMI) is now an essential part of mechanical integrity management, it is using follow the designed standard.
PMI surveys identify alloys used pressure systems, pumps,
Infrared Themography is temperature measure of heat-object by infrared camera. This method can measure the insulated equipment. Max 350oC.
