Question:
Which of the following is solid state welding joining process?
Which of the following is solid state welding joining process?
Show Hint
Solid-state = No melting. Friction welding is like rubbing your hands together to create heat, but on an industrial scale.
Updated On: Jul 4, 2026
- Gas tungsten arc welding
- Resistance spot welding
- Friction welding
- Submerged arc welding
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept Solid-state welding processes produce joining at temperatures below the melting point of the base metals.
Step 2: Meaning Fusion welding (like Arc welding) requires the metals to melt and mix together. Solid-state welding uses pressure and/or friction to bond the surfaces.
Step 3: Analysis GTAW and Submerged Arc are fusion processes. Resistance welding involves localized melting. Friction welding joins metals through mechanical friction and pressure without reaching the melting point.
Step 4: Conclusion Thus, friction welding is the correct example of a solid-state joining process. Final Answer: (C)
