Phased Array
Performing Phased Array wedge delay, velocity and sensitivity calibrations.
  Collecting encoded scans of welds on high pressure feed lines at power generation plant. Analysis of data is performed using Tomoview software.   Our portable Phased Array equipment is capable of performing tests and acquiring data in situations where other systems can not be used due to fixed restrictions and limited general access. The following pictures give some insight to the types of access problems that are often encountered when performing tests at Refineries or Power Plants. Please contact our Technical Sales Manager (Eric Kivlin) to discuss your requirements for Phased Array or Advanced Flaw Sizing methods at: ekivlin@axiomndt.com [To the Top] Advanced Ultrasonic Flaw Sizing We are able to conduct advanced flaw sizing methods such as phased array, creeping wave, time of flight and delta time of flight techniques. All of these inspection techniques have their place when discerning and sizing cracks and defects. With our highly skilled and qualified technicians we are able to offer solutions and the ability to monitor defects through the use of these advanced flaw-sizing methods. The Phased Array approach provides the most flexible solution when the detection and monitoring of defects is desired. This is due to the equipment having the ability to generate focused longitudinal and shear wave arrays, which can be stored and compared for future reference and comparison. This inspection method can help in establishing growth rates of cracks or erosion/corrosion rates of an in service component.    
The Creeping wave method is an excellent tool for sizing and detecting far side initiated cracks. It is particularly useful when inspecting stainless steels for Intergranular Stress Corrosion Cracking (IGSCC) due to the longitudinal mode generated by this transducer. The Time of Flight (TOF) methods utilize a couple of different techniques. All of which are extremely accurate in determining the depths of near side or far side initiated cracks The Delta Time of Flight method is most accurate when used in conjunction with a specific technique and transducer most commonly focused to the particular geometry of the part under inspection.
