Final answer:
Epoxy bonding with steel is an example of adhesives combined with spot welding, used to enhance the structural integrity and chemical resistance in various industrial applications such as metal construction and automotive manufacturing.
Step-by-step explanation:
The question provided by the student pertains to an example of adhesives combined with spot welding. Among the options given, A. Epoxy bonding with steel is an illustrative example of such a combination. Epoxy adhesives are characterized by their strong bonding capabilities and durability, making them suitable for adhesion to various substrates, including metals like steel. These adhesives react to form a thermosetting polymer with mechanical properties that are beneficial for high-strength applications. When combined with spot welding, an epoxy can provide additional bonding strength along with the mechanical interlocking of the welded spots. This dual bonding method is particularly useful in applications where the structural integrity is paramount and where thermal and chemical resistance is required.
For instance, the use of epoxy as a bonding agent in metal construction or automotive industries is quite common. The adhesive can fill gaps and provide corrosion resistance in addition to the structural support obtained from spot welds.
