Which of the following is NOT a benefit of post-heating?

Question

A. Reduces residual stress
B. Improves weld strength
C. increases cooling rate
D. Helps prevent hydrogen cracking

Answer 1

C. increases cooling rate

Post-heating is typically used to reduce residual stress, improve weld strength, and help prevent hydrogen cracking. However, it does not increase the cooling rate; rather, it usually aims to control the cooling rate to mitigate issues such as cracking and to improve overall weld quality.
