BRIEF HISTORY
The IS0 Recommendation R 636, Code of Syrnbols.for Filler Rods for Gas Welding
of Mild Steels and Low Alloy High Tensile Steels, was drawn up by Technical Committec
ISO/TC 44, Welding, the Secretariat of which is held by the Association Française de
Normalisation (AFNOR).
Work on this question by the Technical Committee began in 1955 and led, in 1958,
to the adoption of a Draft IS0 Recommendation.
L
In September 1958, this Draft IS0 Recommendation (No. 226) was circulated to all
the IS0 Member Bodies for enquiry. It was approved, subject to a few modifications of
an editorial nature, by the following Member Bodies:
Australia France Norway
Belgium Germany Poland
Bulgaria India Republic of South Africa
Burma Israel Spain
Czechoslovakia Italy Sweden
Switzerland
Denmark Japan
Finland Netherlands U.S.A.
Four Member Bodies opposed the approval of the Draft:
Austria
Canada
Romania
United Kingdom
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
1967, to accept it as an IS0 RECOMMENDATION.
Council, which decided, in November

FOREWORD
This IS0 Recommendation is one of a set which also includes the following:
ISO/R 637, Methods of Test for Determining the Mechanical Properties of Weld Metal Deposited
by Filler Rods for Gas Welding Mild Steels and Low Alloy High Tensile Steels.
INTRODUCTION
a reference for the symboliza-
The mechanical properties of the deposited metal which serve as
tion of filler rods must be looked upon as conventional values resulting from the test methods
described in IS0 Recommendation R 637. They cannot be taken to characterize an assembly
welded with the same filler rods because the influence of the parent metal, of the welding pro-
cedure, of the heat treatment after welding or the absence of heat treatment, may cause substantial
changes in the conventional values found during the tests on
