Engineering Assurance for Titanium-Based Defence Systems

Client

Confidential – Defence Sector (United Kingdom)

Project Overview

Carbon Arc was engaged to support the development of a next-generation howitzer system constructed from Titanium Grade 5 (Ti-6Al-4V) — a high-performance alloy selected for its exceptional strength-to-weight ratio, corrosion resistance, and suitability for extreme operational environments.

Our Role

Carbon Arc developed and implemented a comprehensive Control Procedure to ensure full compliance and engineering integrity throughout the manufacturing lifecycle. The procedure detailed:

  • Engineering design validation

  • Welding Procedure Qualification (WPQR) specific to Ti Grade 5

  • Production welding controls

  • Non-Destructive Testing (NDT) protocols

  • Quality assurance and documentation

  • Pressure testing in accordance with the Pressure Equipment Directive (PED), supported by PD 5500

Execution & Oversight

Following procedure approval, Carbon Arc provided on-site technical assurance during the initial production run. Our responsibilities included:

  • Witnessing and verifying start-up processes

  • Conducting audits in accordance with ISO 9001, ISO 3834, and bespoke client specifications

  • Ensuring full traceability and compliance across all manufacturing stages

Outcome

The project delivered a robust, auditable framework that ensured the howitzer system met both regulatory and operational requirements. Carbon Arc’s involvement provided confidence in the integrity of the manufacturing process and established a repeatable model for future production runs involving advanced materials and critical defence systems.
