What Is Welding Engineering?

Welding engineering is an engineering discipline which involves the synergistic application of technologies to result in the creation of welded structures, components or products meeting specified industry standards. Welding Engineering involves the careful consideration and interrelationships of design, materials, processes, and quality requirements.

What Is a Welding Engineer?

A welding engineer is an individual who has been trained to apply welding engineering principles in a manner that will result in the creation of sound welded structures, components or products in the most effective and efficient manner. A Welding Engineer must be able to understand how design, materials, processes and quality requirements interact with and affect one another. The Welding Engineer must consider how these materials and processes will be selected and applied to meet specified service conditions and requirements of applicable drawings, standards and contract specifications.

What Is a Certified Welding Engineer*?

The Certified Welding Engineer (CWEng) Credential is granted to an individual who has qualified as a candidate based on documented training and qualifying work experience per the requirements of AWS B5.16:2006 – Specification for the Qualification of Welding Engineers and has received a passing score for an examination comprised of multiple parts.

A Certified Welding Engineer (CWEng) must demonstrate the following via Qualification and Examination to receive their CWEng Credential:

  • Appropriate knowledge, skills and abilities in the specification and oversight of welding operations leading to the production of weldments that meet requirements of applicable standards. This can include a number of activities, including but not limited to: the interpretation and execution of design drawings and specifications, preparation of welding procedure specifications and related work instructions, oversight of related manufacturing and fabrication activities related to creation of a weldment, and oversight of required quality control activities to verify that weldments meet the requirements of applicable standards.
  • Capable of performing basic calculations for weld joint design, selection of appropriate base and filler metals for specific applications, selection and adjustment of welding processes, verification that welding procedure specifications have been properly qualified and that they are being applied correctly, and verification that resulting welds are in compliance with applicable standards.
  • Be aware of the economics of the welding operation in terms of process selection and application so that welding is performed in the most effective and efficient manner.
  • Capable of effectively communicating with various individuals involved in the manufacturing or fabrication operation including management personnel, design engineers, inspection representatives, welders and welding operators, as well as other individuals involved with ancillary activities.

What Is The Certified Welding Engineer Program?

The AWS Certified Welding Engineer (CWEng) program was developed as a means of recognizing individuals who possess specific knowledge and experience, as defined in AWS B5.16:2006 – Specification for the Qualification of Welding Engineers. The CWEng credential was introduced as a means of recognizing individuals with the necessary knowledge and skills to work as a welding engineering professional based on the knowledge and experience gained through a variety of educational methods.

The AWS CWEng credential is recognized across industry as means of identifying an individual who possesses the knowledge and experience to oversee the production of weldments in a manner that reduces risks and improves safety. As such, these industry professionals are highly regarded and sought after throughout the welding industry.

CWEng Exams Information

A CWEng Candidate is required to take 4 exam parts representing the CWEng Certification Program:

Exam Part
Number of Questions
Passing Score per Exam Part

Passing score for the Certification: Minimum weighted percentage for all four parts must be 70%.

Passing Requirements. Each of the four examinations shall not have an individual score less than sixty percent (60%). Each individual examination shall be weighted and the resulting composite score from sections shall not be less than seventy percent (70%).

  1. Basic Science Fundamentals Examination*: Raw Score × 0.15 = Weighted Score1
  2. Applied Science Fundamental Examination*: Raw Score × 0.15 = Weighted Score2
  3. Welding Related Disciplines Examination: Raw Score × 0.30 = Weighted Score3
  4. Practical Welding and Related Applications Examination: Raw Score × 0.40 = Weighted Score4

Weighted Score1 + Weighted Score2 + Weighted Score3 + Weighted Score4 = Composite Score

*Note: Individuals who have successfully completed the Engineering Fundamentals Exam (formerly the E.I.T. examination) do not need to take these exams. The EFA examination shall be administered by the State Board of Engineering or other governmental entity.

The Basic and Applied Science portion of the examination requirements may be satisfied by successful completion of the Engineering Fundamentals Examination, (formerly the E.I.T. examination). Use 85 × 0.30 in calculating the individual’s score for the Basic Science and the Applied Science Examinations.

0.30 (85) + Weighted Score3 + Weighted Score4 = Composite Score

*NOTE: While the Welding Engineer has established excellent credentials, qualification to this specification alone may not legally qualify the engineer to provide technical services to the public. Contract documents and building or jurisdiction laws may require technical services to be performed under the direction and responsibility of others such as a Registered Professional Engineer. The Welding Engineer designation DOES NOT imply the status of a registered Professional Engineer (P.E.) under the laws of any state or other governmental entity.
