Title:
WELDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/157638
Kind Code:
A1
Abstract:
This welding apparatus is provided with: a first pressing mechanism (30) that presses a cylindrical member (10) in such a manner that a first end section (10a) and a second end section (10b) face each other with a first spacer (38) therebetween; a welding part (40) that is penetrated by the cylindrical member (10), which is pressed by the first pressing mechanism (30) while being fed by a feeding mechanism (20), and has a guide member (42) that guides the cylindrical member (10) toward a welding gun (44), while holding the cylindrical member (10), in such a manner that the first end section (10a) and the second end section (10b) are maintained in a facing state with a second spacer (46) therebetween; and a second pressing mechanism (50) that presses the cylindrical member (10), wherein the first end section (10a) and the second end section (10b) have been welded by the welding part (40), while the cylindrical member (10) is fed by the feeding mechanism (20). Thus, the cylindrical member (10) is smoothly and continuously introduced to the welding part (40) while the facing state of the end sections of the cylindrical member, which are facing each other, is maintained, thereby continuously welding the end sections of the cylindrical member (10), which are in contact with each other, and smoothly and continuously discharging the cylindrical member (10) from the welding part (40), enabling welding distortions to be corrected.
