Main types, design elements and dimensions

Date of introduction 1977−01−01

APPROVED AND promulgated by the decree of the State Committee of standards of Ministerial Council of the USSR from December 12, 1975 N 3880

Proven in 1991 by the Resolution of Gosstandart from 16.05.91 N 695 removed the limitation of the term

REPLACE GOST 11533−65

REPRINT (June 1993) with amendment No. 1, approved in may 1991 (IUS 8−91)

1. This standard establishes the basic types, design elements and dimensions of joints of structures of carbon and low alloy steels, operated by automatic and semi-automatic arc welding under flux with the location of the welded parts under acute and obtuse angles.

The requirements of this standard are mandatory.

(Changed edition, Rev. N 1).

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

A — automatic arc welding under flux;

Ac — automatic arc welding under flux on the steel lining;

APS — automatic arc welding under flux with pre-overlay Podarochnoe seam;

P — semi-automatic arc welding under flux;

PS — semi-automatic arc welding under flux on the steel lining;

PPSh — semi-automatic arc welding under flux with pre-overlay Podarochnoe seam.

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

4. Constructive elements of welded joints, their dimensions and limit deviations thereon shall be as specified in table.2−23.

Note. The application of special methods of automatic submerged arc welding change the size of e compared with the specified in table.2−23.

8. Allowed the displacement of the welded edges relative to each other is not more than:

0.5 mm — for edges with thickness up to 4 mm;

1.0 mm — for edges with thickness 4−10 mm;

0.1 s but not exceeding 3 mm — for edges of a thickness exceeding 10 mm.

9. Maximum deviations podarochnyj joints welded joints of nominal sizes indicated on the drawings, shall comply with:
± 1 mm when a or <6 mm;
± mm — at in or 6 mm.

10. When you vary the thickness of the edges to be welded at an angle =179−160°, the edge having a greater thickness should be a bevel on one or both sides in length  — with one-sided excess of the edges and length  — for two-sided excess edges to the thickness of thin edges s, as indicated on the devil. 1, 2.

The difference in thickness of the welded edges, not exceeding the values given in table. 24, preparation of edges for welding shall be the same as for edges of the same thickness; the structural elements of prepared edges and dimensions of the welding seam welded joints selected at large thickness.

11. At a variable angle coupling parts, the seam is divided into sections and each section of the coupling elements is performed in accordance with the requirements of this standard.
