The non destructive testing is used to check for any structural defects if they are present in the parts. The term non-destructive refers to the fact that the methods incorporated during this testing do not bring any physical damage to the part. The testing is done in order to ensure that the particular part can perform during high stresses and do not break down. These testing are extremely important as it save the amount of money which would be wasted in replacement of damaged parts. One can easily find defects such as corrosion, thinning and fouling with help of these testing techniques. These testing have been used prominently in the aerospace industry, as the parts are very costly to be replaced.
The importance of the Non-Destructive Testing can be felt at the place where one crack could decide the success and failure of the whole project or work. This type of testing has its importance in aerospace industry, chemical, power generation, and oil, gas and petrochemicals industries. You will see the use of this testing in all process driven industries which have high pressure, heat and hazardous substances are a part of the working environment. In such places even a minor accident could be devastatingly harmful so it is of utmost importance to carry out this testing. You must carry out these inspections for both new parts and old devices too, in order to have proper surety.
You can take help of the various techniques to carry out Non-Destructive Inspection. The most common techniques are ultrasound and electromagnetism testing. The ultrasound testing uses an internal rotary system to carry out the inspection of the tubes while the electromagnetism uses eddy currents to check for welds. You can even make use of the fluorescent testing which makes use of the fluid to find the flaws in the parts. The magnetic particle separation and liquid penetrant separation are used in cases where the flaw is to be checked on the surface of the system. You can use the ultraviolet and X-ray testing to check for defects in non-metallic parts.
With the wide importance of this Non-Destructive Testing it is important to hire a professional to carry out this process. You must always look for a company which has experience in carrying out the testing process. It would be a mistake to hand over this important process to any new company. It is better to do a market analysis in order to find reliable testing companies in your area. You can contact them to get an information about their work, there preferred testing techniques in order to choose the best ones. Feedbacks from previous clients can also be extremely beneficial in making an intelligent decision.
