It all depends what method(s), experience, and what level you are. It can be anywhere from about $35,000 - $175,000
Liquid Penetrant Inspection
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.
They are targeted in the engineering field, What they do is check for flaws/weaknesses in the building structures to make sure their in tip top shape to be in.
The best method for detecting defects in welds is Magnetic Particle. You can also use Fluorescent penatrent, and x-ray but they can be time consuming and often unreliable.
The National Board of Boiler and Pressure Vessel Inspectors interprets and enforces the ANSI / ASME codes within the pressure vessel industry throughout North America. "The National Board" stipulates that all pipe welds must have a pressure leak test applied to each assembly before that particular assembly can be put into service. As per B31.3 of the ASME codes the preferred method of testing the integrity of welds is through application of Hydrostatic pressure. All other NDT testing methods e.g. radiography (X-rays), magnetic particle examination, liquid penetrate examination etc. are considered variances to B31.3. Most vessels, flanges, valves and other various pipe assemblies are tested at the manufacturer's facility; the only portion of an assembly that remains untested is the weld (tie-in point) which connects the various assemblies under field conditions. In other instances a leaking flange may require replacement as part of an on-going maintenance program (between turnarounds) creating the need to isolate and hydro-test the connecting weld. It is to these specific areas of the pipe assembly that CAR-BER has focused attention. Traditionally the method of testing welds which connect assemblies in the field involves filling the entire system with testing medium and pressurizing to a pre-determined value (usually 1 1/2 times the working pressure) and maintaining that specific pressure for a pre-determined time. Such a methodology requires extensive person-hours to blank and purge the entire assembly and requires large amounts of medium to perform the test. The requirement for large amounts of medium means that a significant amount of medium must be lost in order to register a noticeable change in pressure. The minuscule amounts of medium required for the CAR-BER equipment to perform, translates to very precise pressure readings should the slightest volume of medium escape the pressurized vessel during testing procedures
certification services in welding, inspection and NDT
Answer If you have an engineering degree, you could probably get a job as a NDT inspector or accident investigator. NTSB offers a course in accident investigation. They take you to a simulated crash and you practise reading the signs. The FAA and NTSB probably have other classes on NDT inspection such as borescope and eddy current inspections.
NDT Techs can make upwards of $70, 000 annual. According to some statistics Ive read. But I think real life wages will go $15-$30 for a Industrial level II RT Tech. with 5+ yrs experience.
Weld mapping are visible marks that are seen on metal welded parts. Either they are welded together or repaired and sometimes you can tell who welded it, and when the weld was placed. Weld mapping is the process of assigning information to a weld joint to enable easy identification of its design (WPS), production (welders, their qualifications, date welded), quality (visual inspection, NDT) and traceability (heat numbers of materials joined & welding consumables). Weld mapping should also incorporate a pictorial identification to represent the weld number on the fabrication drawing, in case the designer does not nominate a weld number. You can use online weld mapping software such as Smart Welding Manager to create weld maps that provide 100% traceability as well as a pictorial representation.

API = American Petroluem Institute NDT = Non-destructive Testing NDT is a process of testing the integrity of a piece of pipe (oil well tubing or casing) that does not damage the material in any way. There is wide range of ways to perform NDT evaluations on tubing and casing products.
I am a non-destructive inspector in the Air force. I want to achieve an associates and then a bachelor's degree.
No.
DP is not actually to do with welding it is a form of NDT which stands for non destructive testing; DP is dye-pen where a white liquid formation is placed over the weld & a normally red enhancer is then placed over the top; this then identifies surface cracks.

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.
It includes inspection of both metallic and non-metallic (polymer and composite) components and structures. According to requirements, NDT can be undertaken during production, post-production, in-service and following repair. Our NDT training institute in Chennai inspection facilities and expertise are also a key component of our failure investigation service and can provide key test data as part of a fitness for service or risk-based inspection procedure-ieqs group NDT LEVEL 1- certification teaches you to perform NDT calibrations and evaluations according to written instructions. NDT LEVEL 2- The ASNT NDT Level II certification program was developed to provide standardized Level II written examinations that employers may use to satisfy the general and specific examination guidelines of paragraphs 8.3 and 8.4, respectively, of Recommended .
