Date of introduction 1977−07−01

The decision of the State standards Committee of the Council of Ministers of the USSR from 28.07.76 N 1826 date of introduction is established 01.07.77

The expiration time limit is removed by the Resolution of Gosstandart from 18.06.92 N 553

REPLACE GOST 14771−69

EDITION (December 2006) with Amendments No. 1, 2, 3, approved in March 1982, December 1986, January 1989 (IUS 6−82, 3−87, 4−89)

1. This standard establishes the basic types, design elements and dimensions welded joints of steels and iron-Nickel alloys and Nickel-based performed by arc welding in a protective gas.

The standard establishes the basic types, design elements and dimensions welded joints of steel pipes according to GOST 16037−80.

2. In the standard the following notation methods of welding:

IN in an inert gas consumable electrode without filler metal;

Of InP in an inert gas non-consumable electrode with filler metal;

IP — in inert gases and their mixtures with carbon dioxide and oxygen consumable electrode;

Up — in carbon dioxide and its mixtures with oxygen consumable electrode.

3. Main types of welded joints shall be as specified in table.1.
