Fabrication drawings are a specific type of detail drawing, whereas some are virtually assembly drawing. It becomes virtually assembly drawing, when the number of items assembled together is fabrication. Fabrication drawing includes list of material parts that help identify all materials used for building up the fabrication. It also includes weld details and the standard symbolic representation of the welds. However, the materials used should be identified according to the codes and standards.
Key Highlights of Fabrication Drawing
• This drawing describes in notes or in the referenced documents about the requirements of heat treatment and stress relief which is imperative especially during the fabrication process and completion of the process
• It also indicates the relevant linear and geometric tolerances
• Sometimes fabrication drawing may include only fabrication details and machining details, which will be shown on a separate drawing
• It also shows other manufacturing information on the drawing
• Fabrication drawings are used in sheet metal, structural steel, stairs, handrails, ballustrading, architectural steelwork
It is further classified into 2 main types and they include:
• Single Part Drawing: This is the workshop drawing, which shows the detail of one part like end plate or single beam. These drawings are presented on small sheet and provide the sufficient information for material cutting
• Assembly Drawing: This is a workshop drawing, which shows about how single parts assemble, such as beam with end plates. This drawing is presented on a small sheet and shows sufficient information for the welder to assemble and weld.
