Interrogation of a problem solving expert system will produce an output,
which is usually advice or an opinion as to the likely cause of the problem
and the recommendations to avoid the problem in the future.
A noteworthy advance in computer hardware in recent years has been
the inclusion of a CD ROM player in the PC to provide a multimedia
capability. Multimedia combines scanned photographs, graphics, animation,
audio and video action with very fast processing and large databases to
provide very visual / interactive software.
T he CD ROM disk is crucial in that with a capacity of 700MB can store
over 250,000 pages of text, or up to 30 mins of video, equivalent to 450 high
density 3.5 in floppy disks.
Commercially available software for the welding engineer
There is now a wide range of powerful software available to the
welding engineer which makes best use of the computing, memory,
knowledge based and/or multimedia facilities of the PC. The IT programs
produced as aids for the welding engineer can be conveniently grouped into
the following categories:
► Repetitive calculations;
► Storage of Information;
► Interpretation of Standards;
► Advisory;
► Simulation;
► Education and Training.
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.
