Definition of a weldment Is a weldment properly described as an assembly made from two or more separate pieces that are permanently fastened together by welding to function as one unit?

Introduction / Context:
Terminology matters for purchasing, inspection, and documentation. “Weldment” appears on drawings, bills of materials, and process plans. Knowing its meaning helps avoid ambiguity and ensures correct fabrication routes and inspections are applied.

Given Data / Assumptions:

• Multiple discrete parts are joined to perform as one assembly.
• Joining method is welding (fusion or resistance, as specified).
• The result is intended to be permanent.

Concept / Approach:
A weldment is the product of a welding operation that bonds two or more components. It can include plates, shapes, machined parts, or castings. The term distinguishes such assemblies from single-piece items (e.g., a single casting or forging) or from bolted assemblies when the joining method is mechanical.

Step-by-Step Solution:

Verification / Alternative check:
Review manufacturing routers where cutting, forming, and fitting operations precede welding; the final deliverable is labeled as a weldment.

Why Other Options Are Wrong:
A weldment is not a casting by definition; a repair on a single part is a welded repair, not a weldment; the term is not limited to sheet metal.

Common Pitfalls:
Omitting nonwelded attachments (e.g., press-in hardware) from the weldment BOM and failing to distinguish sub-weldments from top-level weldments.

Final Answer:
