Out of the following, the joint produced by ______________ has the lowest strength?
Correct answer: A. Soldering
- A. Soldering
- B. Welding
- C. Brazing
- D. Riveting
Explanation
Soldering uses a low-melting filler metal and does not melt or strongly fuse the base materials, so the joint is weaker than brazed, welded or riveted joints. Welding generally produces the strongest metallurgical joint among these methods when properly performed.
