Types of Welds and Joints

SPOOLER uses three types of weld definitions and one type of joint definition. These are:

The types of welds and joints are described in the following sections.

Implied Welds

IWELD components provide a link in the Fabrication database to the position of a weld that must be inserted to join two piping components or tubes. For example: fit a flange onto the end of a tube. You do not have to explicitly define these welds as they are implied by the nature of the components involved.

A connection can have an IWELD element associated with it if:

• It has a Ckey (Connection key) of types BW or SW.

  Note:
  If you have explicitly defined a weld (RWELD element) to connect the two components, the software will not insert a implied weld at that point.

Real Welds

RWELD components link to explicitly defined Shop or Field welds in the Design database. They are normally inserted in Design but can also be added in SPOOLER, to break up a spool.

Attached Welds

AWELD components provide a method for numbering the welds required for welded attachments. Typically these are used to secure the piping network to the support ATTAchments. The number of welds on each attachment can be defined in SPOOLER, use the Modify > Attached Welds from the main menu bar.

Implied Joints

IJOINT components define the connection between two non-welded piping components or tubes (for example, bolted flanges, compression joints or screwed connections). You do not have to explicitly define the details of these joints as they are implied by the nature of the components involved.

A connection can have an IJOINT element associated with it if:

• It has a Ckey (Connection key) of types CP, FL or SC.

• Neither of the components are Gaskets.
