The type of welded joint illustrated is...

🔍 Key Concepts

• Look at how the pipe fits into the fitting in the illustration – is one piece slipped into another, or are two edges pressed end‑to‑end? • Think about where the weld metal is located: around an outside ring, between edges, or just along a thin edge plate. • Recall that in piping systems, small‑diameter pressure lines commonly use a joint where the pipe is inserted into a recessed seat on a valve body or flange.

💭 Think About

• Ask yourself: does this drawing show two plate edges being joined, or a pipe inserted into a recessed pocket on a larger component? • Which weld term is normally used in pipework when the weld is made around the outside of a pipe that has been inserted into a counterbored recess? • Which option describes only a weld along the thin edges of plates, and which option describes two pieces butted directly together in line?

✅ Before You Answer

• Verify whether the joint shows a recessed “socket” or counterbore in the larger fitting that receives the pipe end. • Check if the weld bead forms a ring around the outside where the pipe meets the fitting, instead of directly between two squared pipe ends. • Eliminate the choice that applies to flat plate edges only, and the one where parts are aligned end‑to‑end with no overlap.
