As the Internet is already widely used by many welding engineers as a
source of IT, guidelines are provided on how the vast amount of information
on welding engineering related topics can be accessed.
Welding engineering software for the PC
The first IT packages written for the welding engineer were for
carrying out simple calculations such as the preheat temperature level to
avoid hydrogen cracking. However, as the PC became more powerful (faster
computing speeds and additional memory), their use was extended to mass
storage of information in databases such as for welding procedures and
welder qualification. More recently, software has incorporated novel
programming techniques, expert systems for knowledge based advisory type
software and multimedia systems for advisory and education and training
software. The main advantage of expert systems is that they are capable of
encapsulating expert knowledge, which may be largely subjective. Thus,
operation of an expert system differs from that of a conventional software
which progresses in a predetermined, step by step manner until a result is
obtained e.g. the preheat temperature or the output of a database.
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;
