Qualification testing of welders for under-water welding - Part 1: Diver-welders for hyperbaric wet welding (ISO 15618-1:2001)
This standard applies to welding processes where the skill of the diver-welder has a significant influence on weld
quality.
This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and
certification for the approval testing of diver-welder performance for the welding of steels underwater in hyperbaric
wet environment. The recommended format for the certificate of approval testing is given in Annex A.
During the approval test the diver-welder should be required to show adequate practical experience and job
knowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to be
approved, information on these aspects is given in Annex B.
This standard is applicable when the diver-welder's testing is required by the purchaser, by inspection authorities or
by other organisations.
The welding processes referred to in this standard include those fusion welding processes which are designated as
manual or partly mechanised welding. It does not cover fully mechanised and fully automatic processes (see 5.2).
All new approvals should be in accordance with this standard from the date of this issue.
However, this standard does not invalidate previous diver-welder approvals made to former national standards or
specifications, providing the intent of the technical requirements is satisfied and the previous approvals are relevant
to the application and production work on which they are employed.
Also, where additional tests should be carried out to make the approval technically equivalent it is only necessary
to do the additional tests on a test piece which should be made in accordance with this standard.

This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by June 2002, and conflicting national standards shall be withdrawn at the latest by
June 2002.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

Introduction
This standard covers the principles to be observed in the approval testing of diver-welder performance for the fusion
welding of steels in a hyperbaric wet environment.
The ability of the diver-welder to follow verbal or written instructions and testing of his skill are therefore important
factors in ensuring the quality of the welded product.
Testing of skill to this standard depends on welding methods in which uniform rules and test conditions are complied
with, and standard test pieces are used.
This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating
to the diver-welder's competence in the various fields of application. Tests should be carried out in accordance with
this standard unless additional tests are specified by the relevant application standard when these should be applied.
The test weld can be used to approve a welding procedure and the diver-welder provided that all the relevant
requirements, e.g. test piece dimensions, are satisfied.
The diver-welder's skill and job knowledge continue to be approved only if the diver-welder is working with
reasonable continuity on welding work within the extent of approval.
1 Scope

quality.
This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and
certification for the approval testing of diver-welder performance for the welding of steels underwater in hyperbaric
wet environment. The recommended format for the certificate of approval testing is given in Annex A.
During the approval test the diver-welder should be required to show adequate practical experience and job
knowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to be
approved, information on these aspects is given in Annex B.
This standard is applicable when the diver-welder's testing is required by the purchaser, by inspection authorities or
by other organisations.
The welding processes referred to in this standard include those fusion welding processes which are designated as
manual or partly mechanised welding. It does not cover fully mechanised and fully automatic processes (see 5.2).
All new approvals should be in accordance with this standard from the date of this issue.
However, this standard does not invalidate previous diver-welder approvals made to former national standards or
specifications, providing the intent of the technical requirements is satisfied and the previous approvals are relevant
to the application and production work on which they are employed.
Also, where additional tests should be carried out to make the approval technically equivalent it is only necessary
to do the additional tests on a test piece which should be made in accordance with this standard. Consideration of
previous approvals to national standards or specifications should be at the time of the enquiry/contract stage and
agreed between the contracting parties.
The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.
