🔍 Key Concepts

• Flush construction in ship hull plating and what it means about how plates meet • Difference between butt joints and fillet joints in welding • How shell plates are arranged along the length of the vessel (longitudinal vs transverse joints)

💭 Think About

• Ask yourself: when two plates are in the same plane and meet edge-to-edge so the surface stays smooth, what type of welded joint is normally used? • Which weld name refers to the type of joint rather than whether it is long/short or on the outside/inside? • Which option describes how plates are joined, not just the fact that the weld runs along a seam or is unbroken?

✅ Before You Answer

• Identify which choice refers specifically to a weld on an edge-to-edge joint between plates in the same plane • Eliminate any option that mainly describes the weld’s length or continuity rather than the joint geometry • Make sure the term you choose is standard for flush shell plating where the outer surface of the hull remains smooth
