Title:
BRAZED JOINT, BRAZING METHOD AND DEVICE FOR PROMOTING BRAZING FILLER METAL FLOW AND DEFORMATION AND GAS ESCAPE
Document Type and Number:
WIPO Patent Application WO/2024/011766
Kind Code:
A1
Abstract:
A brazed joint, brazing method and device for promoting brazing filler metal flow and deformation and gas escape. The brazed joint comprises a first base material (100), a second base material (200) and a brazing seam (300). The brazing seam (300) is formed by using a brazing filler metal to fill a gap between a brazing surface of the first base material (100) and a brazing surface of the second base material (200) and melting the brazing filler metal to join the first base material (100) to the second base material (200), and the brazing seam (300) is a recessed brazing seam. The gap comprises a first distance (L1) and a second distance (L2), wherein the first distance (L1) is located at an edge of the gap, and the first distance (L1) is greater than the second distance (L2); and the first distance (L1) is in curved transition with the second distance (L2).
