____ is used to reduce the rate at which welds cool.
A) Preheat
B) Annealing
C) Normalizing
D) Stress relieving

Question

Quizplus · Accepted Answer

Preheating is a technique used to reduce the cooling rate of welds by heating the base metal before welding. This helps to minimize the risk of cracking and stress build-up in the welded joint. Annealing, normalizing, and stress-relieving are different heat treatment processes used to improve the properties of metals, but they do not directly affect the cooling rate of welds.
