In the rapidly evolving world of aerospace manufacturing, few things are more critical than the integrity of welded components. That’s why Snowline Engineering treats quality control not as a finishing step, but as the foundation of our entire welding process.

Due to the flight-critical nature of many welded aerospace components, whether in terms of performance or safety, the industry is notorious for carrying exceptionally strict quality standards. Those standards are laid out in a long list of certifications, approvals, and compliances depending on the product application and the requirements.

Two of the most widely used standards in modern aerospace manufacturing are given by the National Aerospace and Defense Contractors Accreditation Program (NADCAP) and the American Welding Society (AWS). Snowline takes a look at the basics of those standards below, along with a quick guide for professional welders and jobseekers aspiring to become certified aerospace welders themselves.

Navigating AWS Certification in Aerospace Welding

AWS is the gold standard for process control and reliability in aerospace welding. AWS provides independent accreditation for special processes including welding, ensuring every supplier meets rigorous international requirements for quality and consistency.

An AWS-certified aerospace manufacturer like Snowline consistently meets a number of strict quality controls:

• Commitment to excellence and continuous improvement throughout all welding operations.
• Confidence for aerospace OEMs and primes that the firm can reliably produce parts to exacting specifications.
• Full alignment with aerospace supply chain needs, including detailed documentation and audit trails for fusion welding, resistance welding, and brazing.
• The ability to compete for and retain contracts with leading manufacturers in the sector.

The process for earning AWS accreditation is exhaustive. Every welding procedure, test, and operator must pass strict audits and reviews, underscoring the reliability of the final product.

The Role of AWS D17.1: Welding Code for Aerospace Fusion

The AWS D17.1 standard is the technical backbone for aerospace welding projects in the U.S. and worldwide. D17.1 defines the requirements for fusion welding of aerospace hardware, including titanium, nickel, magnesium, iron, and cobalt alloys. Not surprisingly, the standard is referenced by titans throughout the aerospace industry including the FAA, DoD, and NASA.

Some key AWS D17.1 features include:

• Detailed inspection classes (A, B, C) that assign rigorous acceptance criteria based on part criticality. Class A covers load-bearing or pressure-critical structures where even minor defects are unacceptable.
• Performance Qualification tests (WPQ), requiring welders to demonstrate proficiency with real materials under production conditions.
• Procedures for repair welding to ensure continued compliance across the lifecycle of aerospace components.

At Snowline, all welds adhere to D17.1 standards, guaranteeing clients safety, mechanical reliability, and regulatory compliance.

Becoming a Certified Aerospace Welder: What It Takes

The pathway to becoming a certified aerospace welder in California is shaped by the demanding requirements of AWS D17.1. Welders typically begin with TIG or fusion welding coursework, then progress through hands-on training in precision sheet metal, titanium, and advanced alloys. Courses culminate in performance-based certification tests, with the AWS D17.1 joining the Certified Welder and CWI credentials as essential qualifications for industry employment.

Here’s a quick overview of the most important aerospace welding certification steps:

• Complete accredited training, often a six-month program combining classroom learning with supervised lab work.
• Pass a written and hands-on exam as specified by AWS D17.1 covering materials, fabrication, inspection, and weld performance.
• Maintain certification through ongoing education and periodic endorsement exams for new materials or advanced processes.
