Title:
BRAZING METHOD
Document Type and Number:
Japanese Patent JPH03234391
Kind Code:
A
Abstract:

PURPOSE: To realize a brazing assembly free from a brazing flaw by filling a brazing gap with a molten brazing filler, metal and forming a brazing filler metal layer in which a metallic mesh attached thereto is a nucleus.

CONSTITUTION: A metallic mesh 6 is attached to a brazing gap 3 between a tubular brazed member 1 and a tubular brazed member 2. Its gap 3 is filled with a molten brazing filler metal. In such a state, a brazing metal layer 5 in which the metallic mesh 6 is a nucleus is formed. The molten brazing filler metal fills up the brazing gap through a minute opening part of the metallic mesh whose used wire diameter is 0.03mm to 0.12mm, and also, a thin metallic mesh is arranged in the brazing gap. In such a manner, the eccentricity and the inclination of the member to be brazed can be prevented.
