IS 18734 : 2024/ISO 6847 : 2020 Welding Consumables - Deposition of a Weld Metal Pad for Chemical Analysis
NATIONAL FOREWORD
This Indian Standard which is identical to ISO 6847 : 2020 'Welding consumables - Deposition of a weld metal pad for chemical analysis' 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.
The committee decided to adopt ISO 6847 : 2020 standard under dual numbering system.
This document outlines the procedure for depositing a weld metal pad for chemical analysis. It applies to various welding methods and consumables, including covered electrodes, wire electrodes, tubular cored electrodes, solid rods, tubular cored rods, wire-flux combinations, and strip-flux combinations. It also encompasses a wide range of materials, including non-alloy and fine grain steels, high strength steels, creep-resisting steels, stainless and heat-resisting steels, nickel and nickel alloys, as well as copper and copper alloys.
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.
