Introduction

DNV GL approval is mandatory for materials used in constructing and repairing vessels, offshore structures, and pressure equipment that are required to meet their stringent class rules. Our DNV GL-certified aluminum wires—including the high-strength and cryogenic alloys—are continuously monitored and audited to ensure they maintain the required properties for critical welds in harsh marine and sub-zero environments. This certification provides an internationally recognized guarantee of quality and performance for shipyards and offshore fabricators globally.

Specification

CertificationDNV GL (formerly DNV/GL) Product Type Approval
Applicable StandardDNV GL Rules for Classification of Ships, Offshore Units
Material FocusER5183, ER5356 (for marine), specialized cryogenic alloys
Key PropertyCorrosion resistance, Toughness, High fatigue life
AuditingSubject to annual DNV GL manufacturing and material audits

Applications

  • Structural welding of hulls, superstructures, and components for DNV GL-classed vessels (including yachts, ferries, and LNG carriers).

  • Fabrication of pressure vessels and piping for offshore oil & gas platforms.

  • Cryogenic service welding for LNG tanks and storage facilities.

  • Any marine application requiring compliance with the International Maritime Organization (IMO) standards.

FAQ

  • Q: What is the primary focus of DNV GL testing for aluminum wire?
  • A: Testing focuses heavily on the weld's mechanical properties (tensile, yield), chemical composition consistency, and, crucially, the impact toughness, especially for alloys used in low-temperature or high-stress environments.
  • Q: Do I need separate DNV GL approval if my material has ABS approval?
  • A: Yes. While the technical specifications may overlap, each classification society requires its own specific approval and regular auditing for certified material to be used on vessels or structures classed by them.

Advantages

  • Global Acceptance: DNV GL is one of the world's leading classification societies, granting immediate material acceptance at shipyards and energy projects worldwide.

  • Safety and Integrity: Guarantees the weld material meets the highest standards for safety-critical, high-stress, and harsh-environment applications.

  • Seamless Qualification: Eliminates the need for end-users to perform time-consuming and expensive material qualification testing.

  • Cryogenic Reliability: Certification often includes verification of low-temperature toughness for specialized applications like LNG transport.

Payment and Shipping

  • Documentation: Provision of the DNV GL Type Approval Certificate and supporting MTCs with every relevant shipment.

  • Logistics: Dedicated service to global shipbuilding centers (South Korea, China, Europe, USA).

  • Volume Support: Capable of supplying the massive volumes required for large-scale shipbuilding projects (e.g., cruise ships, carriers).
