Full title and description

ISO 15618-1:2016 — Qualification testing of welders for underwater welding — Part 1: Hyperbaric wet welding. This International Standard defines requirements, test procedures and acceptance criteria for qualification testing of welder‑divers performing hyperbaric wet welding on steel, and includes recommended certificate formats and guidance on job knowledge and safety aspects.

Abstract

Specifies essential requirements, ranges of qualification, test conditions, acceptance requirements and certification for the qualification testing of welder‑diver performance for hyperbaric wet welding on steel. The document covers manual and partly mechanized fusion welding processes relevant to diver‑welders, provides a recommended certificate format (Annex A) and guidance on job knowledge, materials and safety (Annex B). It does not cover fully mechanized or fully automatic processes.

Scope

This part of ISO 15618 applies to qualification testing of welder‑divers carrying out hyperbaric wet welding on steel. It defines the essential variables for testing, the range of qualification (including joint types, positions and materials), test‑piece and consumable requirements, acceptance criteria for destructive and nondestructive examination, and the form and content of qualification certificates. It is intended for new qualifications issued from the date of publication; previous national qualifications remain valid where their technical intent is satisfied.

Key topics and requirements

• Definition of essential variables and ranges of qualification for hyperbaric wet welding.
• Specified test pieces, welding positions and joint types for qualification testing.
• Requirements for filler materials, fluxes and consumables appropriate to underwater wet welding.
• Acceptance criteria including destructive testing and nondestructive examination methods.
• Certification and recommended format for qualification certificates (Annex A).
• Guidance on job knowledge, safety and process understanding required of the welder‑diver (Annex B).
• Exclusion of fully mechanized and fully automatic processes from this part.

Typical use and users

Used by maritime and offshore engineering organisations, dive contractors, welding qualification bodies, classification societies, inspection and quality‑assurance teams, and training centres. Typical applications include inspection and approval of diver‑welder competencies for in‑service repair, maintenance and construction tasks where hyperbaric wet welding is employed on steel structures.

Related standards

ISO 15618 is a multipart series addressing underwater welding. ISO 15618-1:2016 supersedes ISO 15618-1:2001 (withdrawn) and is accompanied by other parts in the series such as ISO 15618-2 (qualification testing for hyperbaric dry welding / diver‑welders and welding operators). Related ISO documents on welder qualification and welding quality (for example ISO 9606 series and ISO 3834 series) are routinely used alongside ISO 15618 for comprehensive competency and quality management.

Q: What does it cover?

A: It covers essential variables for qualification testing, test pieces and procedures, filler and flux requirements, acceptance criteria (destructive and nondestructive), recommended certificate format (Annex A) and guidance on job knowledge and safety (Annex B). Fully mechanized and fully automatic welding processes are excluded from this part.

Q: Who typically uses it?

A: Offshore/marine contractors, dive‑welding crews, certification and qualification bodies, classification societies, QA/QC inspectors and training organisations concerned with underwater welding competency and safety.
