Red Seal Ironworker (Structural/Ornamental) Practice Exam

Which type of structural connection is commonly used in ironwork?

1. Welded connection

2. Bolted connection

3. Screwed connection

4. Casted connection

The correct answer is: Bolted connection

A bolted connection is widely recognized as a common type of structural connection in ironwork. This method involves fastening structural components together using bolts, which provide significant strength and flexibility. Bolted connections allow for easy assembly and disassembly, making them advantageous for structures that may require adjustments or repairs over time. They also facilitate the installation process, as bolts can be tightened to achieve the desired clamping force, ensuring a secure connection. In addition to the ease of use and repair-ability, bolted connections are especially effective in structural applications where load distribution, tension, and shear forces need to be accommodated. This type of connection is often used in structures like bridges, buildings, and towers, where maintaining structural integrity under various loads is crucial. While welded connections are also prevalent in ironwork, they create a more permanent bond and may require extensive equipment and skilled labor for execution, which could complicate construction. Screwed connections tend to be more associated with smaller-scale applications or non-structural components. Casted connections are less common in contemporary ironwork, as modern steel structures primarily rely on the other connection types for flexibility and strength. Thus, the use of bolted connections stands out in ironwork for their practicality and effectiveness in structural design.
