Question 1 of 27070

When a new section of shell plating is being installed, the proper weld sequence must be followed to __________.

🔍 Key Concepts

• Weld shrinkage and distortion when welding large plates on a hull • How weld sequence (order and direction of passes) affects stresses in the structure • The difference between controlling distortion vs. simply making welding easier or faster

💭 Think About

• Ask yourself: What is the main structural concern when adding a large new shell plate to a hull and applying a lot of heat? • Which option focuses on the behavior of the metal and the hull shape as it cools, rather than on the welder’s comfort or convenience? • Consider which choice best reflects good shipyard practice to keep the hull fair (smooth and true to shape).

✅ Before You Answer

• Identify which option deals with stresses and distortion in the steel itself, not just weld position or sequence preference. • Eliminate any option that talks mainly about welder comfort (e.g., easier positions) instead of hull integrity. • Verify which choice aligns with the goal of keeping the hull form and plating alignment as close to original as possible after welding.
