REPRINT (August 1992) with amendment No. 1, approved in June 1989 (IUS 8−89)

1. This standard establishes the basic types, design elements and dimensions welded joints of steels. The standard does not specify the size of the gap between the welded parts before welding.

The standard does not apply to welded joints of corrosion-resistant steel.

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

 — wire electrode;

 — consumable nozzle;

electrode, the cross section of which corresponds to the shape of the cross section of the welding space.

For structural elements of welded joints the following notation:

,  — thickness of the welded parts;

the length of the seam;

 — distance from the face of the shelf brand to the top surface of the fin;

 — the width of the cutting edges;

 — the height of the convexity of the weld;

 — the width of the remaining substrate;

 — the height of the remaining pads;

 — the thickness of the electrode, the cross section of which corresponds to the shape of the cross section of the welding space;

 — thickness melting of the mouthpiece (the larger of the thicknesses of the plate or channel);

 — the calculated gap and the conventional gap between the two collected under electroslag welding of parts without taking into account the convergence or divergence of the welded parts with the weld shrinkage on the basis of which calculate the dimensions of the welded parts.

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

Table 1

4. Structural elements of the longitudinal sections of welds shall be as specified in table.2.

Table 2

Note. The weld joint of variable cross section and variable curvature is allowed to pair with the alignment to the rectangle.

5. Constructive elements of welded joints, their size and the limit deviations shall be as specified in table.3−12.
