Material strength tests are conducted in most of the industries such as automotive, construction, power plants, railways, military, aviation, and manufacturing industries. It is needed as the strength and durability of the material used in the industrial plants are crucial to the safety and successful operation of the plant. . There are different types of tests which are performed to see whether a material is fit for use or not. These tests are conducted on the materials and the machines being used in the structural units in a plant or in a civil construction, so that they can meet the desired strength levels. With the advent of technology specific testing procedures are developed to assess the strength of different types of materials.
Positive material identification
This test helps in letting us know the amount of metal alloy used in a particular product. One need not worry before conducting this test because it won’t cause any disruption in the process. This is one of the most reliable tests to assess the composition of a material. This test is conducted to know the exact amount of a metal used because the type and quantity of metal used is very important to determine the strength of a system or unit..
These tests are carried out majorly at the places where construction work is going on, to check if the pipes are fit for housing purposes. Once the work of fitting is over, the pressure test is conducted so as to check the amount of leakages and whether the joints are properly attached. Two important persons involved in pressure testing are the plumber and the manager, who is the leader of the project. These tests are conducted to prevent leakages and other problems related to pipelines.
It’s a non-destructive testing procedure, which is used to test the hidden flaws inside the equipment. The machine used in this process is similar to the X-ray machine.
Salt spray testing
This procedure is used to check corrosion resistance of coated samples. It is used for the evaluation of corrosion resistance of finished surfaces or parts.
It is the most commonly used method to detect the strain-hardening of metals. Sometimes it is tested on materials to see up to what amount it could be stretched. Through a tensile test, we can measure ultimate tensile strength, maximum elongation and reduction in area.
This test gives us information about the defects and flaws found in a particular product. The ultrasonic testing is based on the pulse velocity method. A thin layer of couplant is used over the material while conducting this test.Browse through http://www.abcndt.com for more information.
