【 摘 要 】

The scope of this paper is the identification of an optimum technological solution for brazing aluminum alloys using crack tested specimens. To obtain conclusive results, these tests are conducted on two sets of different specimens. Thus, we get two sets of data which we will compare. These tests are part of the standardized series of tests required by the ASME standards. These are called exfoliation tests. They are used to determine where the crack occurs: in the base material or in the filler material. Thus, we can determine whether the cracking is cohesive or adhesive.
