🔍 Key Concepts

• Plate fairing and distortion control during construction or repair • How localized heating affects the shape of steel plate • Difference between weld preparation and post‑weld correction

💭 Think About

• Ask yourself: Is this procedure mainly about preparing for welding, fixing stresses in a weld, or correcting plate shape after it has distorted? • Think about what happens when a small strip of steel is heated and then allowed to cool on a larger plate—does it expand or contract, and how could that change the plate’s shape? • Which option best matches a controlled process used by shipyards to straighten or fair hull plating without cutting it out and replacing it?

✅ Before You Answer

• Identify which choices talk about before welding, which talk about after welding, and which talk about changing plate shape. • Consider what shipyards do when plating becomes warped or buckled after welding: do they usually cut it out, or is there a heat‑based correction method? • Verify which option explicitly refers to removing or correcting distortions in plating, not just treating the weld itself.
