3. Most existing software systems in the fabrication industry are tools for
large companies.
3. The first database management systems could not create new procedures
for new application.
Part 2. Weldspec 4
Taking all this into account, The Welding Institute (TWI), Cambridge,
U.K., and C-spec, Pleasant Hill, California, have collaborated to develop a
new version of Weldspec. Weldspec 4 has been designed to help the welding
engineer write and draft new welding procedures while still giving the
benefits of speed and editing of existing procedures in Microsoft Windows®.
The software comes from many backgrounds, including the following:
- Worldwide welding and application standards from such organizations as
ASME, AWS, European standards and API;
- Industry practice in developing, qualifying and using welding procedures;
- Typical interactions between customer, fabricator and inspector;
- Welding engineering and metallurgy;
- Software development and knowledge representation techniques.
Software so vitally based on knowledge and recommendations from
standards needs to be frequently updated; indeed, ASME IX is updated
annually. Because anything hard coded within software is difficult to change,
Weldspec's knowledge base is stored externally to the main program so it can
be modified.
Managing welder performance qualifications (WPQs) is very similar to
welding procedures: Both are designed by standards. Variables that must be
recorded, the extent of approval given by a test and the destructive and
nondestructive examination (NDE) regimes are specified in national and
international standards.
However, unlike welding procedures, WPQs are only valid for a
specified time without practice or additional testing. Certificates expire, so
the fast sorting capability of computers is even more beneficial. By
integrating another program called Welderqual 4 with Weldspec 4 to share a
database of welder details, WPQs can be created directly from welding
procedures.
An integrated software system such as Welding Co-ordinator can help.
Welding Co-ordinator is designed to be used live to manage fabrication as it
is progressing. It is usually based around an electronic weld map, weld data
sheet or weld schedule, into which data are entered as welds are designed,
engineered, welded and tested. The weld map would also usually have some
space for approval, either weld by weld, or once a project or structure has
