Foreword

For the 1996 edition, the "Rules for Building and Classing Steel Vessels - Part 2: Materials and Welding" was re-titled "Rule Requirements for Materials and Welding (Part 2)." The purpose of this generic title was to emphasize the common applicability of the material and welding requirements in "Part 2" to ABSclassed vessels, other marine structures and their associated machinery, and thereby make "Part 2" more readily a common "Part" of the various ABS Rules and Guides, as appropriate.

Accordingly, the subject booklet, Rules for Materials and Welding (Part 2), is to be considered, for example, as being applicable and comprising a "Part" of the following ABS Rules and Guides: - Rules for Building and Classing Steel Vessels - Rules for Building and Classing Steel Vessels Under 90 Meters (295 Feet) in Length

- Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal Waterways - Rules for Building and Classing Mobile Offshore Drilling Units

- Rules for Building and Classing Steel Barges

- Rules for Building and Classing High-Speed Craft

- Rules for Building and Classing Floating Production Installations

- Rules for Building and Classing Offshore Support Vessels (OSV Rules)

- Rules for Building and Classing High-Speed Naval Craft

- Guide for Building and Classing Liftboats

In the 2002 edition, Section 4, "Piping" was added to Part 2, Chapter 4, "Welding and Fabrication". This Section is applicable only to piping to be installed on vessels to be built in accordance with the ABS Rules for Building and Classing Steel Vessels, the ABS Rules for Building and Classing Offshore Support Vessels, or the ABS Rules for Building and Classing High-Speed Naval Craft.

In the 2004 edition, Part 2 was reorganized to incorporate the new divisions "Rules for Testing and Certification of Materials," comprised of Chapters 1, 2 and 3 and Appendices 1, 4, 5, 6 and 7, and "Rules for Welding and Fabrication," comprised of Chapter 4 and Appendices 2 and 3. This reorganization was purely an editorial change intended to clarify the requirements for the materials themselves and for construction, respectively, and does not contain any technical changes
