A. General
1. Scope
1.1 These rules apply to all welding work carried out on the ship's hull, including the superstructure and deckhouses, its internal and external structures, and equipment components forming part of the ship's structure, e.g. hatch covers, masts, king posts or crane substructures welded to the ship's hull. See also Chapter 1, Section 1, A.1. and A.2.
1.2 They also apply in analogous manner to cargo tanks which are not an integral part of the ship's hull and are not pressure vessels within the meaning of Section 3 (e.g. prismatic type A tanks, according to the Rules for Construction I, Part 1, Chapter 6).
2. Other relevant rules and regulations
The design and dimensioning of welded joints is also governed by the provisions of the Rules for Construction
I, Part 1, Chapter 1, Sections 19 "Welded Joints and 20 "Fatigue Strength" and the performance of the work is also subject to the provisions of Section 1, N. of the said Rules for Construction. For other relevant standards, see Chapter 1, Section 1, B. of these Rules for Welding.
3. Weld performance
Welded joints in hull structures shall be prepared, made and inspected in such a way that their quality
characteristics are equivalent to those of the base materials to be joined. This means that they may not
deviate from the prescribed form and internal condition by more than the limits allowed by the prescribed
weld quality grades according to Table 1.9 or by the evaluation categories used as a basis for the notch
category classification for the proof of fatigue strength (cf. Rules for Construction I, Part 1, Chapter 1,
Section 20). The same applies in analogous manner to the other quality characteristics; cf. also C.
