How do you check for such defects as the degree of penetration and fusion?
To check for defects like incomplete penetration and lack of fusion in welding, you can use techniques like visual inspection, ultrasonic testing, penetrant testing, or radiographic testing. Visual inspection involves visually examining the welded joint to look for discontinuities. Ultrasonic testing uses high-frequency sound waves to detect defects below the surface. Penetrant testing involves applying a dye to the weld and then inspecting for any surface-breaking defects. Radiographic testing uses X-rays or gamma rays to detect internal defects.
What are the disadvantages of various NDT methods?
Ultrasonic testing can be limited by material thickness and rough surfaces, while magnetic particle testing requires magnetic materials and surface preparation. Radiographic testing exposes workers to radiation, and dye penetrant testing can miss subsurface defects. Eddy current testing is sensitive to material conductivity variations and surface conditions.
What is the basic principle of energy?
The basic principle of energy is that it cannot be created or destroyed, only transformed from one form to another. This principle is known as the law of conservation of energy. It means that the total amount of energy in a closed system remains constant over time.
State the basic principle of the pressure tube log?
The basic principle of the pressure tube log is to measure the pressure difference between two points along a tube to calculate fluid flow rate. By measuring the pressure at these points and knowing the fluid characteristics, the flow rate can be determined using a formula based on Bernoulli's principle.
How do you calculate radiographic sensitivity?
Radiographic sensitivity can be calculated as the ratio of the number of true positive results to the sum of true positive and false negative results, multiplied by 100 to get a percentage. This formula helps to evaluate how well a radiographic test can detect true positive cases out of all actual positive cases.
How is radiographic testing used in welding?
Radiographic testing is similar to taking of an x-ray of a weld. It checks for integrity, penetration, and other necessary factors.
Explain the basic principle of magnetic particle testing?
By changing the permiability of ferromagnetic meterials, surface and near surface discontinuities are traced, is the principle of magnetic particle testing.
