The advantage of thermit welding is that
A. All parts of the weld section are molten at the same time
B. Weld cools almost uniformly
C. Results in a minimum problem with internal residual stresses
D. All of the above
Answer: Option D
Solution (By Examveda Team)
Advantages of thermit welding is listed below:• The weld formed has high mechanical strength.
• Excellent corrosion resistance as compared with other forms of weld.
• It is highly stable to repeated short circuit pulses.
• The electrical resistance remains unchanged over lifetime of the installation.
• All parts of the weld section are molten at the same time.
• Weld cools almost uniformly.
• Results in a minimum problem with internal residual stresses.
