display the information. The hypertext links allows the user to browse
through information held either on the same server or, more importantly, on
any other computer connected to the Internet. The WWW protocol covers
most types of information, including multimedia, and the method of
communication.
Accessing and Searching the WWW
To enable a user to gain access to the Internet an account is required
with a "Service Provider". When the user logs on to the Service Provider's
server, the software will allow the user to browse the Internet accessing and
retrieving information from the various servers/web sites.
To search for particular information on the WWW, a "search engine"
is used to produce an index or a catalogue of web pages. Searching involves
simply filling in a form with words or phrases which describe the
information you require. The search engine will produce a list of Web pages
which best match the query.
Welding engineering IT on the WWW
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;
