Abstract (en)

[origin: FR2771321A1] The assembly method for two parts (22, 32) includes the following stages: - form at least a first contact of extended length on the first part (22) and at least a second extended contact (34) on the second part (32), with at least one of the contacts being segmented and including at least two extended segments (24, 26); - deposit a brazing element on each segment; - apply a thermal process designed to give to each brazing element a spherical shape (28, 30); - assemble the first and second parts (22,32) by aligning the first and second contacts, and; - carry out a second thermal process designed to fuse the brazing parts, so as to form a continuous brazed strip between the two parts (22,32). The length of the each segment is less than 10 times the width of each segment.
