NATIONAL FOREWORD

This Indian Standard (Part 3) (First Revision) which is identical to ISO/TR 25901-3 : 2016 'Welding and allied processes - Vocabulary - Part 3: Welding processes' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Welding General and its Applications Sectional Committee and approval of the Metallurgical Engineering Division Council.

This standard was first published in 1957. In order to ensure harmonization of the vocabulary used in the field of welding on an international level, the Committee decided to revise this standard to bring it in line with ISO standards by splitting in four parts as the requirements of IS 812 : 1957 are covered in multiple ISO standards.

This Indian Standard is published in four parts. The other parts in this series are:

Part 1 General terms

Part 2 Health and safety

Part 4 Arc welding

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical with those used in Indian Standard. Attention is especially drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, it should be read as 'Indian Standard'; and

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