Zusammenfassung:	PCT No. PCT/SU85/00094 Sec. 371 Date Jul. 20, 1987 Sec. 102(e) Date Jul. 20, 1987 PCT Filed Nov. 26, 1985 PCT Pub. No. WO87/03330 PCT Pub.

The length of the rod-end blanks is so selected that the weld joints (6, 7) be established, after the upsetting procedure, across the maximum cross-section of the sucker-rod heads (8 and 9).
