What is the purpose of a weld map in a structure?

• A. Document maintenance schedules for welding equipment
• B. Record paint schemes
• C. Document locations, types, sizes, and continuity of welds across the project
• D. Track welding crew hours

Answer: (C)

A weld map is a detailed record that shows exactly where welds are located on a structure and what kind of welds they are. It identifies locations, weld types (such as fillet or groove), sizes (throat or leg dimensions), and whether welds are continuous across connections. This single reference lets fabricators, inspectors, and engineers verify that every required weld is present in the correct form and that welds meet the design specifications and code requirements. It supports quality control and traceability, making it easier to plan inspections, coordinate repairs, and manage future modifications. It’s not about maintenance schedules, paint schemes, or tracking crew hours.
