Which type of joint configuration is often used for joining two workpieces end to end?

The type of joint configuration that is commonly used for joining two workpieces end to end is the butt joint. Butt joints involve aligning the pieces so that their edges meet directly, allowing for the application of weld along the joint line. This configuration is particularly advantageous in situations where a strong, flush surface is desired, as it creates a strong weld and allows for effective penetration of the weld metal into both workpieces. Furthermore, butt joints are often used in structural applications where maintaining a clean and continuous surface is crucial for aesthetics and performance.

Lap joints, on the other hand, involve overlapping pieces, which is not suitable for end-to-end connections. Edge joints typically connect two pieces along their edges but aren't as effective for high-stress applications compared to butt joints. Corner joints are designed for meeting pieces at an angle and are used in specific structural assemblies, rather than for end-to-end connections. Thus, butt joints are the preferred choice for this type of welding configuration, ensuring strength and integrity in the joined workpieces.
