Since its introduction in 2009, the cost-effective price of […]
X ray introduction knowledge –Creating a Portable X-Ray Machine —https://hv-caps.biz A startup company is developing a flat-panel source of x-rays that could help make the imaging technique portable. The company’s panels are made using techniques commonplace in the semiconductor industry and would be combined with flat-panel detector to make a briefcase-sized x-ray machine powered by […]
HV Capacitor Application — Xray , what is X-rays — https://hv-caps.biz Definition X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, a machines sends are individual x-ray particles, called photons. These particles pass through the body. A computer or special film is used to record the images that […]
NDT Method Summary -eddy current testing — https://hv-caps.biz Alternating electrical current is passed through a coil producing a magnetic field. When the coil is placed near a conductive material, the changing magnetic field induces current flow in the material. These currents travel in closed loops and are called eddy currents. Eddy currents produce their own […]
Ultrasonic Testing — NDT Method Summary — https://hv-caps.biz High frequency sound waves are sent into a material by use of a transducer. The sound waves travel through the material and are received by the same transducer or a second transducer. The amount of energy transmitted or received and the time the energy is received are […]
Magnetic Particle Testing –NDT Method Summary — https://hv-caps.biz Magnetic Particle Testing A magnetic field is established in a component made from ferromagnetic material. The magnetic lines of force travel through the material, and exit and reenter the material at the poles. Defects such as crack or voids cannot support as much flux, and force some […]
1) Penetrant Testing–NDT Method Summary — https://hv-caps.biz No single NDT method will work for all flaw detection or measurement applications. Each of the methods has advantages and disadvantages when compared to other methods. The table below summarizes the scientific principles, common uses and the advantages and disadvantages for some of the most often used NDT […]
Visual and Optical Testing (VT) Radiography (RT) Magnetic Particle Testing (MT) –by https://hv-caps.biz The most basic NDT method is visual examination. Visual examiners follow procedures that range from simply looking at a part to see if surface imperfections are visible, to using computer controlled camera systems to automatically recognize and measure features of a […]
HV Capacitor application– NDT, What is NDT? — by https://hv-caps.biz The field of Nondestructive Testing (NDT) is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. NDT technicians and engineers define and implement tests that locate and […]
