The main use of the Internet by engineers is to search for technical
information, exchange technical data and to purchase products. Most of the
sites have hypertext links to many more sites that contain related
information on, for example, engineering, materials, manufacturing and non
destructive testing. TWI is typical of the organizations offering technical
information. The information available includes technical data sheets, "best
practice" guides, directory of suppliers, standards information, abstracts of
research projects.
The TWI Web site is accessed by over 6000 users each month and
approximately half of the users are from the USA. The most requested
pages relate to the technical information.
As advertising is freely practiced on the WWW, most commercial
companies have Web pages devoted to the advertising and marketing of
their products. The companies can make text, pictures, sounds and video
available on their Web pages using the hypertext mark-up language. The
ESAB WWW site (http://www.esab.se) contains the following PC programs
available from Business Area Consumables:
WELDCOST - selection of welding process from
economic/productivity calculations;
WELDOC - storage and retrieval of welding procedure
specifications;
PREHEAT -calculation of preheat temperature;
EQUIST -steel grades and their equivalents;
STAR - stainless steel consumables;
CONQUEST - range of steel grades and their recommended
consumables;
THE SCHAEFFLER-DELONG—WRC'92 analysis program is
particularly useful to welding engineers and metallurgists in that it can be
used to select a suitable consumable when welding dissimilar metals, predict
the microstructure of the resulting weld, warn about possible metallurgical
risks on welding, build a database of commonly used metals and their
consumables.
A typical screen display may show the composition of the resulting
weld metal produced when welding 15 Mo 3 steel to AISI316L stainless
steel using the type OK 67.60 consumable. The diagram may also contain a
useful warning on the zones of weld metal compositions (nickel and
chromium equivalents) in which cracking is likely to occur.
