Finding a welding contractor who can consistently meet military standards is a common problem in the supply chain. Many manufacturers can’t do the work because of the complicated technical requirements and required paperwork, creating a possible bottleneck in the manufacturing process, risking delays and unexpected costs.
Advanced Welding Technologies, or AWT, provides expert MIL-Spec welding services built around a quality system certified to military standards. This comprehensively audited framework ensures the integrity and compliance of every weldment we produce for these challenging and high-performance military applications.

What Is MIL-Spec and Why Is It Important?
The term “MIL-Spec” refers to a set of comprehensive standards the US Department of Defense has put together for a wide range of products, materials, and processes. They make sure that all the parts used to build military equipment are of good quality, work well, and are compatible with each other.
MIL-Spec welding standards ensure strong joints that will last when exposed to parameters such as stress, extreme temperatures, vibrations, or bad weather. There are several benefits to partnering with a welding provider that adheres to these military specifications:
Product Quality: The standards mandate that every weld must be executed with precision. This creates exceptional structural integrity and durability in the final product.
Process Repeatability: Helps to ensure every part manufactured is of consistent quality.
Component Reliability: Parts are put through tests to make sure they can handle certain conditions. This makes the equipment they are a part of more reliable and safe.
Regulatory Compliance: Working with a certified welder ensures that all work meets the strict contractual requirements common in military and aerospace projects.
Qualified Personnel and Processes: The certification process verifies that a company’s personnel, equipment, and quality assurance protocols meet the rigorous requirements for their designated applications.
AWT Qualifications and Certifications
At AWT, we hold multiple certifications from military, aerospace, and industrial organizations. These credentials verify our ability to meet specific technical requirements:
- ISO 9001:2015: The international standard for quality management systems, ensuring process consistency.
- ASME Section IX: The standard for qualifying welding and brazing procedures and personnel, critical for pressure vessel and piping systems.
- AWS D1.1, D1.6, & D15.1: The American Welding Society’s structural codes for steel, stainless steel, and railroad equipment, frequently required in military contracts.
- AWS CWI/CWE: Certifications for on-staff welding inspection and education, guaranteeing quality oversight.
MIL-SPEC Standards Applicable to AWT Services and Capabilities
MIL-Spec welding services from AWT are controlled by specifications that govern every stage of fabrication. These documents ensure procedural conformity from initial welder qualification through final inspection and delivery.
AWT is qualified under multiple military and civilian codes to support defense manufacturing requirements. These certifications enable fabrication of components ranging from structural assemblies to pressure vessels using TIG, MIG, and stick welding processes.
Our welders work with steel, stainless steel, aluminum, and other military-grade alloys. We provide facility and field welding services with procedures that meet exact application standards.
Here are the MIL-SPEC standards that apply to AWT capabilities and services:
Welder & Procedure Qualification
Advanced Welding Technologies maintains certified welders qualified under multiple military and aerospace standards. The following specifications govern welder and procedure qualifications for defense manufacturing applications:
- NAVSEA S9074-AQ-GIB-010/248 (Formerly MIL-STD-248): This standard defines the requirements for qualifying both welding and brazing procedures as well as the personnel who perform them in naval applications.
- AWS D17.1 (Specification for Fusion Welding for Aerospace Applications): As the current specification for aerospace and defense welding, this standard replaced several legacy codes and also provides the foundation for NADCAP accreditation.
- MIL-STD-1595A: Although no longer active and formally replaced by AWS D17.1, this legacy standard for qualifying welders in aerospace work continues to appear in older contracts.
Fabrication, Materials, and Design
Military standards for fabrication define the requirements for materials, design, and specific processes like machining. They specify the exact manufacturing steps required to achieve the component’s intended material properties.
- MIL-STD-3040A: Covers requirements for welding and inspecting armor and non-armor steel weldments, directly relevant to our “Military Armament” certifications.
- NAVSEA S9074-AR-GIB-010/278 (Formerly MIL-STD-278): Establishes requirements for fabricating naval systems like machinery and pressure vessels.
- MIL-STD-1946A(MR): The military standard for welding aluminum alloy armor.
- MIL-HDBK-134: The military handbook that provides guidance and technical data for welding copper.
- MIL-STD-22D: A foundational standard for the design of welded joints, relevant to our engineering and design-for-manufacturability services.
Quality, Inspection, and Testing
Military standards for quality control require documented inspection and testing. We follow these procedures to confirm every component meets all project requirements.
- MIL-STD-45662 (Calibration Systems Requirements): Establishes calibration system requirements for test equipment used in our Metrology Services.
- MIL-STD-1330 (Precision Cleaning and Testing): Dictates methods for achieving and verifying cleanliness levels for our Millipore-Testing service.
- NAVSEA T9074-AS-GIB-010/271 (Formerly MIL-STD-271): Outlines requirements for non-destructive testing (NDT) of welds.
Finishing & Coatings
Military specifications also dictate the final surface treatments and coatings applied to finished parts. These standards define the processes for painting and other protective finishes to ensure durability and compliance.
- MIL-DTL-53072: Specifies the requirements for Chemical Agent Resistant Coating (CARC) systems applied in our paint booth and finishing services.
- MIL-A-8625: Defines the requirements for anodizing aluminum, a finishing process for military components.
