What is the proper end anchor weld for a deep long span joist?

1. Finish blading

2. Weld bead

3. Slip joint

4. Anchor plate

The correct answer is: Finish blading

The proper end anchor weld for a deep long span joist is commonly achieved through the process known as finish blading. This technique is essential in ensuring that the load distribution across the joist is maintained and that there is adequate strength at the connection points. Finish blading involves applying a specified welding technique that allows the joist to effectively transmit loads to the supporting structure while also accommodating for any movement or thermal expansion that may occur during the lifespan of the building. Using the finish blading method helps enhance the stability and performance of the joist, particularly in situations where a long span is required. The result is a secure and robust connection that contributes greatly to the overall integrity of the structure. This method is particularly important because it ensures that the weld joins do not introduce weaknesses that could compromise the joist's performance under load. While other options such as weld bead, slip joint, and anchor plate serve specific purposes in construction and structural integrity, they do not provide the same level of effectiveness and stability as finish blading does for deep long span joists, particularly in terms of strength and flexibility in the connection.
