Final answer:
Welding assemblers are the professionals who must interpret blueprints and welding procedures, as they have the necessary expertise to understand and execute the welds as per the provided specifications and standards.
Step-by-step explanation:
Welding assemblers must be able to interpret blueprints and welding procedures. Unlike welding machines, welding torches, or welding electrodes, which are tools or materials used in the welding process, welding assemblers are professionals with the skills and knowledge to understand welding blueprints and carry out welding operations according to specific procedures. Interpreting blueprints involves visualizing the final product from a two-dimensional drawing and understanding the various symbols and notations that indicate welding requirements. Welding procedures outline the steps and standards to be followed to ensure a weld is performed correctly and efficiently, covering aspects like welding technique, material preparation, and safety protocols.
