So, let’s dive in and explore the credentials that can give you a competitive edge in the thriving nondestructive testing sector.

American Society for Nondestructive Testing (ASNT) Certifications

The American Society for Nondestructive Testing (ASNT) is a globally recognized organization that provides certification and training for NDT professionals. Many employers in the industry prefer job applicants with ASNT certification. Let’s dive into three popular ASNT certifications:

ASNT NDT Level I and II

ASNT NDT Level I and II certifications are designed to validate technical competence in specific NDT methods, such as ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT), and liquid penetrant testing (PT). Level I certificate holders possess basic skills to perform specific NDT tasks under supervision, while Level II professionals are qualified to perform and supervise tests, interpret results, and prepare relevant documentation.

To obtain ASNT Level I or II certification, you need to fulfill the necessary training requirements at an NDT training center or through an employer’s in-house program. This entails meeting a minimum number of training hours and work experience in the chosen method before taking a written exam and practical evaluation. Keep in mind that the requirements vary for different NDT methods.


ASNT NDT Level III certification confirms the advanced knowledge and expertise of NDT professionals. These individuals are responsible for establishing and approving NDT procedures, interpreting codes, standards, and specifications, and providing overall supervision and guidance to NDT Level I and II personnel.

To apply for the ASNT NDT Level III certification, you’ll need either a degree in engineering or science and a certain number of years of work experience, or a high school diploma/equivalent with a higher number of work experience years. You must also pass a management examination and a method examination in one or more NDT methods.

American Welding Society (AWS) Certification

The American Welding Society (AWS) offers a specialized certification for NDT professionals involved in weld inspection. Becoming an AWS Certified Welding Inspector (CWI) showcases your expertise in welding processes, codes, and standards, allowing you to stand out from other NDT professionals and attract better job opportunities.

AWS Certified Welding Inspector (CWI)

The AWS CWI certification is highly respected in the industry and demonstrates your competence in evaluating the compliance and quality of welds based on established documentation and visual inspections.

To become an AWS CWI, you need a combination of formal education and work experience in welding fabrication or inspection. You must also attend a training course tailored to the AWS CWI certification and pass an examination that tests your knowledge in welding fundamentals, practical applications, and codebook standards interpretation.

International Organization for Standardization (ISO) Certification

ISO 9712 certification is an internationally recognized certification that demonstrates a professional’s competence in nondestructive testing as per ISO standards. This certification is particularly valuable when seeking employment with organizations that operate on a global scale or highly regulated industries.

ISO 9712 Certification

ISO 9712 certification is available at three levels: Level I, Level II, and Level III. Similar to ASNT certification, Level I professionals perform NDT tasks under supervision, Level II technicians perform and supervise testing, while Level III experts establish NDT procedures and manage NDT personnel.

To attain this certification, you must undergo formal training at an accredited institution, fulfill work experience requirements, and pass a written and practical examination. The tests and requirements differ depending on the NDT method and level of certification.

Factors to Consider When Choosing a Certification

Before investing time and money into an NDT certification, you need to consider employers’ preferences in your region or industry, your career goals, and future industry trends. For example, ASNT certifications may offer broader recognition at a national level, while ISO certifications hold more global appeal.

Networking with NDT Professionals

Connect with fellow NDT professionals, join organizations like ASNT, AWS, or the American Society for Testing and Materials (ASTM), and attend industry conferences and seminars. Networking will help you gain insights regarding certifications and establish valuable contacts that can assist your career development in the NDT field.

In summary, obtaining nondestructive testing certifications will significantly boost your career prospects and enhance your professional credibility. By considering your objectives and the industry’s needs in your area, you can select the most appropriate certification and reap the benefits of career advancement in the competitive NDT field.
