Which of the following is a common method used to apply pressure to glue joints during bonding?

• A. Clamps
• B. Nailing Strips
• C. Power Presses
• D. Small Screws

Answer: (A)

When bonding with adhesive, keeping the joint surfaces firmly in contact while the glue cures is essential for a strong bond. Clamps are the common method because they provide adjustable, uniform pressure along the entire joint, forcing the surfaces to mate evenly and allowing squeeze-out to escape without creating gaps or voids. This consistent pressure helps the adhesive fill the joint properly and keeps parts aligned during cure, which is critical for both strength and accuracy.

Other methods don’t offer the same reliable, surface-wide pressure. Nails or strips of wood used to apply pressure can create holes and leave uneven contact, and can damage surfaces or interfere with the glue bond. Power presses deliver controlled force but are specialized, bulky, and not always practical for typical bonding tasks. Small screws may hold parts together after bonding but aren’t designed to provide initial, uniform clamping pressure and can introduce gaps or damage the joint if driven during curing.

So, clamps are the go-to tool for applying even pressure during bonding, ensuring a strong, properly formed glue joint.
