5. REPRINTING. December 2002
1. This standard establishes the basic types, design elements and dimensions of spot welds of steels, copper, aluminum and Nickel alloys, operated by arc welding.
2. Terms and their definitions in the standard are given in the Appendix.
3. In the standard the following notation methods of welding:
F — submerged arc;
Up — in carbon dioxide consumable electrode;
UPM — in carbon dioxide consumable electrode with the application of longitudinal magnetic field;
The PBSO in carbon dioxide consumable electrode with application of longitudinal magnetic fields with a through-penetration and the formation;
UNIVERSITY in carbon dioxide consumable electrode;
SP — in an inert gas consumable electrode;
IN in an inert gas consumable electrode;
PP — consumable stick electrode with forced non-through penetration and shaping;
PPS — consumable stick electrode with a forced through-penetration and molding;
IPP — in an inert gas consumable electrode to a removable lining.
4. Main types of welded joints shall be as specified in table.1.
5. Constructive elements of welded joints, their dimensions and limit deviations thereon shall be as specified in the hell.1, 2 and table 2−5.
6. For the welding of PP, PPP, PPP size (Fig.1 and 2) must be not less than 1.2
.
7. Size (damn.1 and 2) must be at least 2
when welding with non-consumable electrode and at least
for all other welding methods.
