Engineers typically have more experience with traditional joining methods and often turn to them without considering the advantages of structural adhesives.
Structural adhesives are similar in overlap shear strength to welds and significantly stronger than spot welds, bolts and rivets. They also provide better aesthetics because they do not require refinishing steps or leave protrusions.
