Many companies have written software for in-house use but the
examples described here have been restricted to commercially available
software.
Repetitive Calculations
This group was the first type of software written specifically to help
the welding engineer carry out routine or time consuming calculations.
Topics include the calculation of weld volume, consumable requirements,
cost of fabrication and design calculations for fatigue service. WELDVOL is
typical in that it will allow the user to calculate the volume of weld metal to
be deposited and from this information, the number of rods, or reels of
wire, to be purchased. The program can accommodate a range of arc
processes, joint types and parent metals.
Storage of Information
XWELD is a welding procedure management system. The system is a
multi-user relational database and has the following advantages over a paper
based document control system:
· Integrated drawing system and graphics library;
· Electronic distribution of procedures;
· Search functionality for all essential variables of the procedure;
QMWELD is a complementary program for management of
fabrication information for ensuring that a fabrication is completed on time
and to an appropriate standard. The system gives full traceability with NDT
records.
Interpretation of Standards
FATIGUEWISE is based on BSI 7910 (formally PD 6493),
"Guidance on Methods for Assessing the Acceptability of Flaws in Fusion
Welded Structures". The software allows analysis of structures, for safety
critical applications, using either the fracture procedures or the general
fatigue procedures.
FATIGUEWISE is a typical software for interpreting a standard
which is a complex text procedure. A set of rules derived from the standard
are embedded in the software ensuring that each time an assessment is
made the standard is applied equally rigorously. As most assessments
require numerous calculations, the software will save the user both time and
costs especially when carrying out a sensitivity or critical analysis by varying
one of the input parameters.
The use of a friendly graphical interface ensures that the user is only
asked for information specific to the current assessment.
