Without certification, companies risk noncompliance, costly rework, loss of business opportunities, and potential legal liability.

Key Certifications for Aerospace Welders

The primary certification framework for welding in aerospace is governed by the American Welding Society. Among the most relevant standards is AWS D17.1–Specification for Fusion Welding for Aerospace Applications, which outlines requirements for welding personnel, procedures, and quality assurance. This specification is widely adopted by aerospace manufacturers and is often referenced in customer contracts and regulatory audits. Additionally, many companies require welders to hold an AWS Certified Welding Inspector credential for quality oversight roles. For specialized processes such as electron beam welding or laser welding, supplementary certifications may be necessary, typically defined within customer-specific or internal company standards. Understanding which certifications are relevant to your role and employer is an important first step.

AWS D17.1 Certification Details

AWS D17.1 covers both process qualification and person (welder) qualification. For welders, certification involves demonstrating proficiency in specific welding processes such as gas tungsten arc welding or gas metal arc welding on designated materials—aluminum, titanium, Inconel, stainless steels, and others—in various positions (flat, horizontal, vertical, overhead). The standard dictates acceptance criteria for discontinuities, including porosity, cracks, incomplete fusion, and undercut, which are evaluated through destructive testing (bend tests, tensile tests) and nondestructive testing (radiographic, ultrasonic, or liquid penetrant inspection). In Columbus, testing centers affiliated with the AWS or approved by major OEMs administer practical exams that mirror real-world production conditions. Welders must also pass a written component covering joint design, weld symbols, safety, and material science fundamentals. Typical passing scores are 70% or higher, but some employers set more stringent thresholds.

Other Relevant Credentials

  • NADCAP Accreditation – While not a welder certification per se, NADCAP (National Aerospace and Defense Contractors Accreditation Program) accredits welding processes and facilities. Companies with NADCAP accreditation often require their welders to meet or exceed AWS D17.1 standards. Welders who work in NADCAP-certified shops gain exposure to rigorous auditing and documentation practices. For more information, visit the NADCAP program page.
  • Non-Destructive Testing Certifications – Many aerospace welders also obtain certification in NDT methods such as liquid penetrant inspection (per AWS D1.1 or SNT-TC-1A) or radiographic interpretation. These qualifications enable them to perform or verify inspections, adding significant value to their skill set and making them more versatile.
  • ISO 9606 – While less common in the U.S., welders working on international programs with European partners may need additional qualifications per ISO standards. This is particularly relevant for companies that supply components to Airbus or other global OEMs.

Local institutions and private testing facilities have developed programs tailored to the needs of the aerospace supply chain. Understanding each step will help you plan your career progression.

Training Programs

The first step for many aspiring aerospace welders is enrolling in a training program that covers the fundamentals of welding and specializes in aerospace-grade materials. In the Columbus area, the Columbus State Community College offers a comprehensive welding technology program that includes coursework in advanced processes, metallurgy, and blueprint reading. The college partners with local employers to ensure curriculum aligns with industry demands. You can explore their program details at the CSCC Welding Technology page. Additionally, private training centers like Tulsa Welding School have satellite locations in Ohio and provide accelerated programs focusing on pipe and structural welding, with optional specialized modules for aerospace. Many companies also sponsor in-house training, where experienced welders mentor candidates through company-specific certification programs. For example, GE Aviation’s in-house certification program is highly regarded and often serves as a feeder for other employers.

Practical and Written Exams

After completing training, candidates must pass a practical welding test administered by an AWS-accredited test facility. Exams are performed on coupon test plates or tubes made from the materials and thicknesses representative of production work. For example, a welder seeking certification for TIG welding aluminum might need to produce a butt joint in 0.063-inch sheet in a vertical-up position, followed by a fillet weld in a 0.125-inch corner joint. Welds are then sectioned and inspected for discontinuities using visual examination, bend tests (root bend, face bend) or radiography. The tests are designed to simulate the most challenging production scenarios to ensure the welder can consistently produce sound welds under real conditions. Written exams cover topics such as weld symbols, joint preparation, shielding gases, and AWS D17.1 requirements. Many test facilities in Columbus offer preparatory classes to help candidates succeed.

Recertification and Continuing Education

Aerospace welding certifications are not permanent. AWS D17.1 requires recertification every two to three years, depending on the employer’s quality system. Recertification may involve a simplified test or proof of continued production welding in the same process family. Welders who change employers or processes may need to re-qualify. Many professionals in Columbus pursue ongoing education through AWS seminars, online courses, or attending industry events like the AWS Welding Show. Staying current with evolving regulations—such as updates to FAA advisory circulars or new alloy specifications—is crucial for maintaining marketability. The FAA’s Advisory Circulars page is a key resource for staying informed.

Materials and Techniques in Aerospace Welding

The aerospace industry uses a diverse range of materials, each presenting unique welding challenges. In Columbus, production facilities regularly work with aluminum alloys (e.g., 2024, 6061, 7075), titanium alloys (Ti-6Al-4V), stainless steels (304, 321, 17-4PH), and nickel-based superalloys (Inconel 718, Hastelloy X). Certified welders must understand each material’s thermal conductivity, oxidation tendencies, and susceptibility to cracking. For instance, aluminum requires careful cleaning and preheating to avoid porosity, while titanium demands inert gas shielding to prevent embrittlement. Common welding processes in aerospace include:

  • Gas Tungsten Arc Welding – Preferred for thin sheets and critical joints due to its precise control and low heat input. TIG welding of titanium and aluminum is a core skill for certified welders.
  • Plasma Arc Welding – Used for deeper penetration and higher speeds, often in automated applications for production efficiency.
  • Electron Beam Welding – Performed in a vacuum chamber, producing narrow, deep welds with minimal distortion. Specialized certification is required, and only a few Columbus shops have EBW capabilities.
  • Laser Beam Welding – Increasingly used for high-precision, high-speed joining of thin-walled components. Most laser welding certifications are employer-specific and require additional training.

Inspection and Quality Assurance

Certification is only one piece of the quality puzzle. After welders complete their training and pass exams, ongoing inspection ensures that production welds meet the same standards. In Columbus, aerospace companies employ a multi-tier inspection approach:

  • Visual Inspection – The first line of defense, checking for surface discontinuities, correct contour, and adherence to weld maps. Welders often perform their own visual inspection before submitting parts for further testing.
  • Nondestructive Testing – Techniques like radiographic testing, ultrasonic testing, magnetic particle testing, and liquid penetrant testing are used to detect subsurface flaws. Many certified welders also obtain NDT certifications to perform these inspections themselves, streamlining production.
  • Destructive Testing – Sample welds from production runs are periodically cut and tested for mechanical properties such as tensile strength and bend ductility. This is especially important for first-article qualifications and process revalidations.

Certified welders frequently work alongside AWS Certified Welding Inspectors to document and verify quality. Many companies in Columbus require that welders hold at least one NDT certification, making them doubly valuable. For example, a welder certified in both AWS D17.1 and liquid penetrant inspection can perform their own first-article inspections, reducing turnaround time and inspection costs.

Benefits for Aerospace Companies

Manufacturers in Columbus that invest in welding certification reap tangible benefits that directly impact their bottom line and reputation:

  • Regulatory Compliance – FAA regulations mandate that production operations use qualified procedures and personnel. Certification provides auditable proof of compliance during FAA and customer audits.
