In aerospace manufacturing, every joint must withstand extreme environments without compromise. The integrity of a brazed assembly depends not only on process precision but also on the supplier’s ability to meet rigorous standards across methods, materials, and quality control. Choosing the right partner means aligning technical capability with proven aerospace performance.
In this guide, we outline the key factors for evaluating brazing suppliers and explain why WessDel is a strong choice for aerospace-grade brazed assemblies.
1. Verify Process Breadth
A capable supplier should demonstrate a complete range of brazing options and supporting expertise. Look for:
- Versatile Process Capabilities: A full range of options, including vacuum, inert gas atmosphere, and dip brazing, to accommodate varying joint geometries and manage oxidation sensitivities, ensuring each joint is properly formed and consistent.
- In-House Engineering Expertise: Deep knowledge of fixture design, alloy wetting, and surface compatibility to ensure even joint flow, consistent bonding, and dimensional accuracy.
- Sufficient Brazing Capacity: A brazing capacity that accommodates your largest assemblies, allowing complex or large-scale structures to be handled efficiently without compromising joint integrity. WessDel, for example, can accommodate components up to approximately 48 inches.
When evaluating brazing suppliers, confirm they offer the process versatility described above, then assess how effectively their quality systems uphold aerospace-grade standards.
2. Quality and Standards
In aerospace applications, documentation and repeatability are as vital as technical precision. Verify that the supplier operates under AS9100D and ISO 9001:2015 quality management systems, which are vital for aerospace and defense manufacturing. These frameworks ensure every brazing run follows defined controls, traceability protocols, and corrective-action processes.
Where applicable, compliance with ANSI, ASME, AWS, and Mil-Spec standards provides additional assurance that materials and work adhere to international standards. A reliable supplier also integrates in-process and final non-destructive testing (NDT), such as X-ray or ultrasonic inspection, to validate joint integrity before delivery. Together, these measures confirm that each assembly adheres to functional and regulatory expectations.
3. Advanced Material Expertise
Beyond quality systems, material mastery often separates competent suppliers from exceptional ones. Aerospace brazing demands familiarity with metals that challenge even experienced fabricators. Top suppliers demonstrate:
- Proven experience with AlBeMet and beryllium (Be) assemblies, which require precise control of heat input and joint cleanliness.
- Expertise in aluminum frames requiring post-braze machining, ensuring dimensional accuracy after thermal cycles.
- Expertise in mixed-alloy joints and heat sink assemblies, where dissimilar metal compatibility and thermal management are critical.
These capabilities enable the construction of lightweight yet robust components used in satellites, aircraft, and spaceborne systems.
