Question

Which of the following is a solid state joining process?

• A. Gas tungsten arc welding
• B. Friction welding
• C. Submerged arc welding
• D. Resistance spot welding

Hint:

Solid-state joining processes, like friction welding, do not involve melting the materials.

Answer 1

The Correct Option is B

Step 1: Solid-state Joining Processes
Solid-state joining involves joining materials using heat and pressure, without melting them.Step 2: Process Identification
- Friction welding is a solid-state method utilizing friction-generated heat for joining without melting.
- Gas tungsten arc welding, Submerged arc welding, and Resistance spot welding are fusion welding methods that melt the base materials.
Step 3: Conclusion The correct answer is Friction welding. Final Answer: \[ \boxed{\text{Friction welding}}\]
