Title:
METHOD OF MANUFACTURING ALUMINUM STRUCTURE
Document Type and Number:
Japanese Patent JP2016215248
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of easily manufacturing a sound fillet on an outer surface of a hollow structure of an aluminum structure having the hollow structure and a cylindrical member.SOLUTION: A method of manufacturing an aluminum structure comprises preparing a clad plate which has a multi-layer structure of two or three layers or more including a core material layer made of an aluminum material and a brazing filler material layer arranged on one surface side of the core material layer and made of Al-Si-based alloy, and also includes an element breaking an oxide film in at least one layer of the multilayer structure. The method comprises preparing a cylindrical member 3 made of an aluminum material. A hollow structure 20 having an outer surface side made of a brazing filler material layer and having a through hole 211 into which the cylindrical member 3 is inserted is manufactured from the clad plate. The cylindrical member 3 is inserted into the through hole 211 so as to assemble the aluminum structure 1 having an end of the cylindrical member 3 arranged inside the hollow structure 20. The aluminum structure 1 is heated in an inert gas atmosphere so as to perform brazing processing for joining the hollow structure 20 and cylindrical member 3 together with the braking filler material layer of the clad plate.SELECTED DRAWING: Figure 1
