Certification overview
Welding and NDT are very important for industries. These assures safety and quality in all engineering in the industry. To inforce this principle, various welding and NDT institutes have developed certification schemes, enabling employers to ensure their staff are correctly trained to carry out NDT, welding and inspections.

Aria Azmoon Sanat provides the following types of certifications:

• Welder and welding operator certification
• Welding inspector certification
• NDT level I and II certification
• Management system course certification

Welder and welding operator certification
Welder certification, (also known as welder qualification) are specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The tests consist of many variables, including the specific welding process, type of metal, thickness, joint design, position, and others. Most often, the test is conducted in accordance with a particular code. The tests can be administered under the auspices of a national or international organization, such as the American Welding Society (AWS), or American Society of Mechanical Engineers (ASME), but manufacturers may specify their own standards and requirements as well
Once a welder passes a test (or a series of tests) their employer will certify the ability to pass the test, and the limitations or extent they are qualified to weld, as a written document (welder qualification test record, or WQTR).
Our company with professional and experienced international welding engineers & senior inspectors is ready to take welder approval test according to the company procedure or famous codes and standards including:

ISO 9606
EN 287
AWS D1.1
ASME IX
API 1104

Accepted welders based on their employer's request, will receive national or international certificate.

Welding inspector certification
All successful participants in the welding inspection (CWI) course will receive certificate of proficiency and inspector card according to AWS QC1-96 (standard for AWS certification of welding inspectors).
Benefit of this course is that it has been designed to provide the welding inspector with the necessary information for the successful completion of the American Welding Society's certified welding inspector (CWI) examination.
The welding inspector is one of the "front line" individuals who must check to see if all of the required manufacturing steps have been completed properly. To do this job effectively, the welding inspector must have a wide range of knowledge and skills.
Consequently, this course is specifically designed to provide both experienced and novice welding inspectors a basic background in the more critical job aspects.

NDT level I and II certification
It is recognized that the effectiveness of nondestructive testing applications depends upon the capabilities of the personnel who perform NDT & proper qualification and certification of them.
Nondestructive testing personnel are often certified by their employer or other agency to meet certain qualifications, which are established by industry. Certification is basically a process of providing written testimony that an individual is qualified to do certain work. The qualifications of an individual are based on education, level of training, work experience, and the ability to pass a vision test. In the field of NDT, certification is very important because NDT personnel are often making critical judgments that can have safety and/or significant financial consequences. NDT personnel must have a great deal of confidence in the results of their work. Since many of the NDT methods do not produce a record of the inspection results, certification presents objective evidence of the knowledge and skill level of the individual performing an inspection.
The procedure used to assure that NDT personnel possess the qualifications necessary to do competent work includes:

• training to gain the necessary knowledge
• experience under the guidance of knowledgeable people
• qualification examinations to demonstrate that competency has been achieved
• Certification to document successful demonstration of competency.

NDT Methods
Certification can be obtained in number of NDT methods, which are listed in the table below.

 

NDT Certification Levels
NDT personnel are generally certified to several different levels of competence within each of the NDT methods they are working. The levels are Level I Limited, Level I , Level II, and Level III.
Level I technicians are only qualified to perform specific calibrations and tests, and acceptance or rejection determinations allow little or no deviation from the procedure. Level I technicians are under close supervision and direction of a higher level tester. The level I position is not the trainee level, but the first level a trainee reaches upon demonstrating ability in specific tests. Level I Limited personnel are restricted even more in what they can do. They are usually trained to a specific procedure and can perform only certain types of inspections on a certain set of components.
Level II technicians are able to set up and calibrate equipment, conduct the inspection according to procedures, interpret, evaluate and document results in all the testing method(s) utilized by the certificate holder. The technician can provide on the job training for Level I and Level I Limited and act as a supervisor. The technician can also organize and document the results of the inspection. They must be familiar with all applicable codes, standards, and other documents that control the NDT method being utilized.
Level III technicians are capable of establishing techniques and procedures; interpreting codes, standards, and specifications; and designating the particular nondestructive testing methods, techniques, and procedures to be used. They must also have knowledge of materials, fabrication, and product technology. Level III technicians are responsible for training and examining Level I and Level II's. Usually Level III technicians are in administration, supervision, or management positions, or are owners of a testing laboratory. Some Level III technicians also become consultants.

Certification Requirements
There are a number of organizations that have produced documents that recommended or specify the minimum qualifications for certification. The following is a partial list of documents pertaining to the certification of NDT personnel in the US.

• SNT-TC-1A, The American Society for Nondestructive Testing, Recommended Practice, Personnel Qualification and Certification in Nondestructive Testing.
• ATA-105 Aviation Transport Association, Guidelines for Training and Qualifying Personnel in Nondestructive Testing Methods.
• AIA-NAS-410, Aerospace Industries Association, National Aerospace Standard, NAS Certification and Qualification of Nondestructive Test Personnel.
• ISO 9712, International Organization for Standards, Nondestructive testing -- Qualification and certification of personnel.

The education and work experience requirements for the various specification are common or similar. Typical requirements are summarized in the table below for qualification levels I and II. Please consult the certification documents to assure that information is correct for your situation.
NDT training can be obtained at colleges, vocational-technical schools, the Armed Forces, commercial training companies and through individual company training departments. A list of educational institutions offering NDT classes can be found in the education resources section of this web site.
To be considered for certification as a Level III an individual must:

• Have graduated from a university or college with a degree in engineering or science, and have at least one year of experience comparable to that of a Level II in the applicable NDT method(s).
• Have completed with passing grades at least two years of engineering or science study at a university, college or technical school and have two years of experience comparable to that of a Level II in the applicable NDT method(s).
• Have four years of experience comparable to that of a Level II in the applicable NDT method(s).

Certification Examinations
Once the education, training and work experience requirements have been met and documented, a certification examination must be taken. The examination process actually includes several exams. For certification to Levels I and II a general, a specific, and a practical, exam must be completed with a passing grade of 70 percent for each exam and a composite grade of 80 percent (determined by averaging the results of the three exams). The Level III exam process includes completion of a basic, a method, and a specific examination with a passing grade of 70 percent for each exam and a composite grade of 80 percent. Level I and II exams must be administered by an NDT Level III and this is often done within a particular company. Level I, II and II exams can also be taken through a central agency such as ASNT. Central certifications provide technicians with documentation of qualification that is recognized nationally.

Visual Examination
It is important that NDT personnel have good near visual acuity and color vision. Therefore, an eye test must be taken to insure that natural or corrected near distance acuity is acceptable. Depending on which specification the company uses for certification, an individual must be able to read a Jaeger Number 1 (or equivalent) type and size letter at no less than 12 inches (for one eye). Determining contrast of color or shades of gray is also generally required.

Management system course certification
All volunteers in AAS management system courses will receive official certificate from NISCERT company.
Aria Azmoon Sanat & NISCERT have cooperation agreement about training and certfication of management system courses.
NISCERT is one of the most popular Certification Registration Bodies in Germany and the word, NIS stands for Nuclear Engineering System and originates the company's operational background and indicates the high level of expertise and knowledge lied in the company.
