WELDED CONNECTING PART BETWEEN MAIN PIPE BODY AND BOTTOM PART THEREOF

PURPOSE: To suppress the formation of blowholes in the welding of a joint between a tube body and a bottom part at a commercially reasonable expense. CONSTITUTION: A bottom part has an extended part for centering for a tube body 1, this extended part overlaps the tube body 1 and, as a result, the tu...

Zusammenfassung:	PURPOSE: To suppress the formation of blowholes in the welding of a joint between a tube body and a bottom part at a commercially reasonable expense. CONSTITUTION: A bottom part has an extended part for centering for a tube body 1, this extended part overlaps the tube body 1 and, as a result, the tube body 1 has an end face where a gap 9 exists between the tube body 1 and the extended part 5 with respect to the tolerance in the diameters. In a weld joint which is between the tube body 1 and the bottom part 3 and which consists of a contact face 15 formed with the end face of the tube body 1 and the inner stepped end face 13 of the bottom part 3, the contact face 15 is provided with at least one ventilating connecting part 21 for the gap 9. Consequently, the gap 9 is in communication with the outside air existing on the other side of the contact face 15.
