Question of the day

The following statement is true or false: Preheating is sometimes used in repair welding to reduce residual stresses.

Explanation:
Preheating before welding is a technique used to manage cooling rates and residual stresses. By raising the base metal temperature, the weld and surrounding material cool more gradually, which reduces the thermal gradient that drives contraction. This lowers the tensile residual stresses that would otherwise form as the metal solidifies and cools. In repair welding, where the workpiece may have varied geometry and restraints, slowing the cooling also helps prevent cracking and distortion in the heat-affected zone. Preheating can also aid hydrogen diffusion out of the weld area and reduce peak hardness, further lowering cracking risk. Because of these effects, preheating is sometimes used in repair welding to reduce residual stresses.

    Still prepping, but the bite sized lessons and clear diagrams are helping me lock in the basics. The randomized questions feel fair and mostly target the exam's core topics. I also like using the flash cards on the go; it keeps the material fresh during commutes.

    Not a perfect fit yet for me. Some questions felt repetitive and a bit surface level, but I still picked up useful tips and gained better time awareness. The flash cards are decent, and the explanations helped my weak spots somewhat. I hope the next update tightens the gaps.
