JIG FOR WELDING HEADER AND AIR COOLING HEAT EXCHANGER MANUFACTURING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a jig for welding a header which enables an operator to easily and promptly weld the header to a heat exchanger core.SOLUTION: A jig 1 for welding a header is used for connecting a header 60 to a heat exchanger core 50 including multiple tubes by welding and includes: multiple rotary members 10 which are respectively formed into annular shapes; connection members 20 which connect the multiple rotary members 10 so that the multiple rotary members are spaced away from each other in an axial direction; and holding members 30 which hold the heat exchanger core 50 along the connection members 20.
