Patent number: 7635078Abstract: This invention relates to a method of brazing while the thickness of the opening between materials being brazed can not be maintained constant or can not be adjusted in the appropriate range. In order to solve this issue the porous material of metals or metal alloys consisting of Ni, Cu, Ti, Al, Ag or W should be utilized. The metallic porous material is inserted into the brazing opening mentioned above by using the softness of it, and is made to hold the brazing solder and to reinforce the bonding part after brazing.Type: GrantFiled: February 6, 2006Date of Patent: December 22, 2009Assignee: Kanto Yakin Kogyo Kabushiki KaishaInventors: Tadashi Ariga, Kiichi Kanda
