How do you examine the welds after the tests and check for weld quality?

You can have visual inspection, x-ray, ultrasound, magnetic testing. The seam can be ground, polished and tested with a stain marker. You can weld a test piece and have it submitted to destructive testing where it's pulled or bent until failure.

How do calculate a welding rods per inch dia in ms pipe welding?
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.

What is the plural of weld?
The plural of 'weld' is 'welds', as in "He made several welds to the car frame."
Why NDT is important in industry?
NDT is important in most industries because it is used as a Quality Assurance. The technicians will inspect for errors in welds and stress fractures from manufacturing.
What does a arc welder do?
it welds
What is a clean process that welds complex materials with a highly concentrated arc?
A clean process that welds complex materials with a highly concentrated arc is?
How many more spot welds were added to the 2012 Toyota Camry?
56 additional spot welds were added Adrees Toyota of Berkeley
How is radiation used to check welds?
A source of gamma radiation is placed on one side of the weld, and a photographic film is placed on the other. Bubbles and weak points will appear on the film.
How do calculate a welding rods per inch dia in ms pipe welding?
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.
Why should you not touch radioactive element with bare hands?
Radioactive sources are used in several different ways. In medicine they can be used for investigation as tracers, or to give treatment to tumors for example. In industry they can be used to examine welds for defects. In nuclear plants they can be used to check and calibrate instruments. Different types and strengths are required depending on the task in hand.
Why aircrafts body is riveted?
Air craft are mostly made from aluminum. Welding aluminum parts is very difficult to do. Conventional welding is not applicable to aluminum although some techniques to that exist. However there are limitations to welding in general 1) Difficult to control the quality of the welds. For this purpose the welds need to go thru x-ray or ultrasound or some other quality assurance procedure. 2) Welds are prone to fatigue failure. Fatigue failure happens without much warning thus difficult to catch during inspections. 3) Welds are difficult to undo/redo for planes in service. Service or inspection may require access under the fuselage (skin) of a plane. Undo and redo the weld is dangerous to perform on the winds of a plane where fuel tanks are located. With comparison to rivets welding also in disadvantage 1) Ductility of welds is lower. (Ductility - ability to plasticly stretch without failure) Thus if overstress occurs the weld breaks suddenly and rivet deforms to allow stress redistribution. Plastic deformation is easy to detect during inspection.
What are uses of nuclear energy toward industry?
Mainly generation of electricity. However production of isotopes used to examine structures such as welds, to calibrate instruments, or to incorporate into devices such as smoke alarms, is also important. These radioisotopes are produced in small reactors built for the purpose. They also produce medical radioisotopes.
