NATIONAL FOREWORD

This Indian Standard which is identical with ISO 14731 :1997 ‘Welding coordination — Tasks andresponsibilities’ issued by the International Organization for Standardization ( ISO ) was adopted by theBureau of Indian Standards on the recommendations of the Welding Applications Sectional Committeeand approval of the Metallurgical Engineering Division Council.

In this adopted standard, some terminology and conventions are, however, not identical to those usedin Indian Standards. Attention is especially drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should beread as ‘Indian Standard’.

b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point ( ) as the decimal marker.

In reporting the results of a test or analysis made in accordance with this standard, if the final value,observed or calculated, is to be rounded off, it shall be done in accordance with IS 2 :1960 ‘Rules forrounding off numerical values ( revised)’.

WELDING COORDINATION — TASKS ANDRESPONSIBILITIES

1 Scope

This International Standard identifies the quality related responsibilities and tasks included in the coordination ofwelding related activities.

In any manufacturing organization welding coordination may be undertaken by one or a number of persons.

Welding coordination requirements can be specified by a manufacturer, contractor an application standard.

2 Definitions

For the purpose of this standard the following definitions apply.

2.1 manufacturing organization: Welding workshops or sites under the same technical and qualitymanagement.

2.2 welding coordination personnel: Personnel who have responsibilities in the manufacturing operation forwelding and welding related activities and whose competence and knowledge has been demonstrated by e.g.training, education and/or relevant manufacturing experience.

A welding coordinator is a person carrying out one or more coordination tasks.

2.3 welding inspection: Examining, testing and measuring of welding related matters.

3 Tasks and responsibilities

3.1 Quality related activities

Table 1 shall be used as a guide to allocate quality-related tasks and responsibilities to welding coordinationpersonnel. It may be supplemented for special applications. Not all the items will necessarily apply to allmanufacturing organizations or quality system requirements and a selection should be made as appropriate, e.g.where there is no destructive testing or non-destructive testing, No. 1.8.2 of table 1 does not apply.

3.2 Specification of tasks and responsibilities

Each single activity in table 1 maybe associated with a number of tasks and responsibilities such as:

— specification or preparation;

— coordination;

— control;

— inspection, checking or witnessing.

1

IS 15327:2003

1s0 14731 : 1997

Where welding coordination is carried out by a number of persons, tasks and responsibilities shall be allocated foreach person.

The manufacturer shall nominate at least one authorized welding coordinator.

Welding coordination is considered to be the responsibility of the manufacturing organization.

For some work activities the coordination tasks and responsibilities may be carried out by subcontractors.Subcontracted activities shall remain subject to welding coordination in accordance with this InternationalStandard.
