Abstract
In this report, the relationship between wettability, bond strength and mutual solubility was discussed on the basis of experimental results shown in the previous report. Consequently, taking a microscopic view of bonded layer of brazed joint, it may be said that wettability has a close relation to mutual solubility and bond strength of brazed joint has also, that is, the greater mutual solubility is, the better wettability is and the larger bond strength is. So, it may be given as a conclusion that wettability and bond strength in brazing are related closely through a factor of mutual solubility between solid base metal and liquid filler metal.
