Document Type and Number:
WIPO Patent Application WO/2013/039289
Kind Code:
A1
Abstract:
The present invention pertains to a cooling ring for welding bellows, a cooling ring for welding used in the manufacture of bellows, which include multiple pairs of diaphragms, wherein a pair of diaphragms are formed of a first diaphragm and a second diaphragm disposed to face the first diaphragm. The cooling ring includes: an arc-shaped main body which is disposed to bring the first diaphragm and the second diaphragm into contact with each other in the state in which the main body is in contact with the first diaphragm and/or the second diaphragm, and includes copper; and a plating layer which is plated on the main body, wherein the plated layer includes at least one selected from the group consisting of nickel and chromium. Since the present invention is provided with the arc-shaped main body, which includes copper, and with the plating layer, which is plated on the main body, the present invention does not generate, during welding, the powder of metals such as copper, aluminum, gold, silver or the like, which have high electric conductivity.
