Weld Map

A controlled engineering drawing or document identifying the location, identification and characteristics of welds within a fabricated assembly.

Definition

A Weld Map is a controlled engineering drawing or document that identifies the location, identification number, weld type and associated information for welds within a fabricated assembly, piping system or pressure vessel. Weld Maps support fabrication, inspection, non-destructive testing, repair management and quality assurance by providing complete traceability of individual welds.

Why It Matters

Weld Maps provide the location and identification of welds to support fabrication, inspection and quality management.

In Practice

Weld Maps commonly identify weld numbers, weld types, welding procedures, inspection requirements, repair history and associated non-destructive testing results to support complete weld traceability.

Common Misuse

A Weld Map identifies and tracks individual welds within an assembly, whereas a Welding Procedure Specification defines the approved method used to produce those welds.
