What should be checked for when inspecting the appearance of a brazed joint?

When inspecting the appearance of a brazed joint, assessing the even color and texture is crucial. A uniform appearance typically indicates a proper bonding process where the filler metal has flowed correctly and adequately wetted the surfaces of the base metals. This homogeneity in color and texture signifies that the joint has been sufficiently heated and that the filler material has adequately fused with the base metals, leading to a strong, reliable bond.

In contrast, irregularities in color or texture could point to problems such as incomplete wetting or overheating, which can compromise the integrity of the joint. By focusing on evenness, one can infer the quality of the brazing process and subsequently the joint's strength and durability.
