What is an ultrasonic densitometer?
An ultra sonic densitometer is used to measure density. in this type of measurement the thickness of the test sheet ant the reference sheet are kept constant and equal. Ultrasonic source is on one side of the sheets and ultrasonic sensors on the other side. ultrasonic waves that are given by ultrasonic source are made to pass through the test sheet and and the reference sheet simultaneously... both the sheets absorb a part of the rays and leave the ramaining. the sensors present on the other side of both the sheets give the measure of ultrasonic rays thet are left after they are absorbed by the sheets... the value of sensor on the test sheet's side is compared with the reference sheet side .since thickness and density of reference are known, test sheet's density is determined. or the densitometer may be directly calibrated to give the result after comparision
In which industries is ultrasonic testing often used?
Ultrasonic testing is used in the welding industry to test the strengh of the steel after it is welded together. It is also used in the medical profession for a variety of uses.
What is the use of couplant in the process of ultrasonic testing?
couplant nothing but oil,greace,water,this can be used buring the ultrasonic test between work piece and probe.many prupose wo avoid air
What is ultrasonic cleaning?
Ultrasonic cleaning is cleaning through ultrasonic waves with some chemicals.
In what industries is an ultrasonic thickness tester used in?
Ultrasonic thickness gauges are used in several industries. Gauges are available to test the thickness of metal, glass, ceramic, plastic and concrete so are common in any field which works with these substances.
What does sound weld mean?
It's "ultrasonic weld," rather than "sound weld." Sounds more "engineering-ish," anyway. This is done by clamping two objects together - usually plastic ones, but thin metal can also be ultrasonically welded - and directing a high-power beam of ultrasonic energy at the mating point. The beam causes heat, which makes the two materials in the joint melt. When they cool down, they're fused together.
What type of diagnostic testing is a definitive test for osteoporosis?
Ultrasonic bone density testingUltrasound and CT Scans are typically ised to check for this condition.
Is the most accurate test for osteoporosis?
Ultrasonic bone density testing
What test is the most accurate for testing osteoporosis?
Ultrasonic bone density testing
What is the minimum thickness of plate required to do ultrasonic test?
most specifications have a limit on 10mm

How do you check the welding penetration and welding strength?
Basic test is to cut across the weld and polish the metal. Most times the weld can be seen as a different shade. Inclusions and incomplete fusion are visible You can cut strips across the weld joint and bend them to look for fracturing. Ultimate test is to x-ray the weld. Defects and incomplete fusion can be seen. Same process as an x-ray of your body. Also a section can be cut from the joint and subjected to a tensile test where the piece is literally pulled apart. A good weldor knows when he has produced a perfect weld just by observing the weld bead as it is deposited. Using the correct electrode produces a weld slightly stronger than the base metal.
What is the golden joint welding?
Golden welds is a concept that is used in conjunction with pipeline lay and repair. The golden weld is an accepted weld without solid (and more tangible) proof of strength, for example a break test or load test.
What is a b pressure welder?
This welder is certified to weld on pressure vessels. Testing is done on the weld either by X-Ray or pressure test. The root pass is inspected then the final pass is inspected during the test. If either inspection turns up a flaw, the test is over and you fail.
