Text 4. IT in Welding and Cutting for the Welding Engineer –
PC Programs and the Internet
The PC has now become an essential tool in the work of the engineer for
not only word processing but also specialized tasks such as in design, simulation
and performance assessment. Within the manufacturing industry sector, most
engineers have access to a PC and the vast majority can be classed as frequent
users. It is not surprising, therefore, that in response to the growing market
demand, a wide range of computer programs have been written
specifically for the welding engineer. Whilst PC programs can be
considered to be a mature source of welding engineering IT, over the last
year the Internet has emerged as a new exciting source of welding related
information.
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.
