Certified Welding Inspector:

The Certified Welding Inspector, or CWI for short, is given to people who pass tests written by the ​American Welding Society (AWS) and stands as one of the quality standards in the welding industry. Having this credential signifies a welder’s comprehensive understanding of welding processes, code book standards, and inspection techniques.

For anyone seeking to add credibility to their career in welding, getting a CWI offers a unique pathway, with this prestigious certification in the welding industry.

​Understanding the certified welding inspector (CWI) certification.

The CWI certification is an internationally recognized credential that validates an individual’s expertise in welding inspection. Achieving this certification requires passing a series of tests that assess knowledge in welding fundamentals, practical inspection, and code application. The candidates must complete three exam parts, each evaluating different areas of welding knowledge and skills. A minimum score of 72% on each part is necessary to obtain the CWI credential.

The American Welding Society (AWS) provides flexible training options to accommodate diverse learning preferences for candidates. These include traditional in-person week long seminars, online courses, and custom classes tailored to specific organizational needs. Such flexibility allows candidates to prepare effectively for the certification exams, regardless of their work schedules or job location. ​

The role of a contract certified welding inspector.

A contract CWI operates on a project-by-project basis, offering specialized welding inspection services to various clients across multiple industries. This type of engineering consultant involves several key responsibilities that include:

  • Welding Inspection: Ensuring that welds meet specified codes and standards, and verifying the quality and integrity of welded structures, in accordance with the AWS.
  • Compliance Verification: Confirming that welding procedures adhere to applicable regulations and client specifications.​
  • Documentation: Maintaining accurate records of inspections, welding procedure specifications (WPS), procedure qualification records (PQR), welder qualification test record (WQTR), and all other compliance requirements.​
  • Consultation: Providing expert advice on welding processes, materials, and best practices to optimize quality and efficiency.​

By working on a contractual basis, CWIs can engage with a diverse array of projects, from construction, manufacturing, oil and gas, and many others. This variety not only broadens their professional experience but also enhances their adaptability and problem-solving skills.​

When does your company need a contract CWI?

It can be difficult to know exactly when it is time to bring in extra weld support, but most companies rely on a contract CWI to ensure structural weld integrity, weld safety, and welding code compliance to help with their projects. Whether you’re doing fabrication work or ramping up production and need an extra set of eyes, a qualified CWI can provide immediate oversight exactly when and where you need the welding support.

What are the advantages of using a contract CWI?

Bringing in a welding expert to support your project can be great. That’s why many companies use a CWI on a temporary basis to help support welding activities. Below, I list some of these key advantages:

  • On-Demand Welding Support: Access qualified welding inspectors only when you need them, and without the cost of a full-time hire.
  • Code Compliance: Ensure your welding work meets the AWS or project specific welding standards.
  • Quality Control: Improve traceability, reduce rework, and maintain detailed inspection records.
  • Third-Party Objectivity: Get unbiased evaluations and reviews of your product that supports welding safety, industry compliance, and client confidence.
  • Scalability: Support peak production periods, new installations, or large projects exactly when you need them for as long as needed, then, when the project is completed and meets all the weld standards, the extra contract support can leave the job.
  • Mitigating Risk: Identify weld defects early and help to prevent structural or safety failures later on down the line.
  • Contractor Versatility: Contract CWIs often have multi-industry experience, bringing best practices from a diverse welding background.

FREQUENTLY ASKED QUESTIONS:

Below, I discuss some FAQs about certified welding inspectors.

A CWI is responsible for inspecting and ensuring the quality, safety, and compliance of welded structures and components. Their duties often include reviewing welding procedures, examining welds for defects, conducting visual inspections, interpreting welding codes, and documenting inspection results.
A contract CWI works on a temporary basis for their clients, and is often hired for specific projects or inspection needs. They have the flexibility to choose their projects and can work across multiple industries or locations for many different companies. A full-time employee who is a CWI is employed by a single company and works on the welding projects their employer requests.
To become a CWI, candidates must meet eligibility requirements based on a combination of education and relevant work experience. For example, someone with a high school diploma needs five years of welding-related experience, while those with higher education may require less. Once eligibility is confirmed, the next step is to prepare for and take the AWS CWI exam. The CWI exam consists of three parts: Part A covers welding fundamentals; Part B tests practical inspection skills; and Part C focuses on navigating and interpreting codebooks. AWS provides preparation options such as in-person seminars and online courses to help candidates succeed. Passing all three parts is necessary to earn certification.
Certified Welding Inspectors are in demand across many industries that rely on safe and structurally sound welding. These include construction, oil and gas, shipbuilding, manufacturing, aerospace, and power generation. In these sectors, CWIs play a critical role in ensuring welds meet safety codes and quality standards. Because of the broad range of welding applications, CWIs often find themselves working on bridges, pipelines, structural steel frames, aircraft components, or in the industrial sector. Their expertise ensures that welded materials can withstand stress, pressure, and environmental conditions, protecting both infrastructure and peoples lives.
