Where can I learn to read welding blueprints online?

admin

Does anyone know of a site where I can learn to read welding blueprints online?  As in a freebie, nada, zip, zero cost site.  Surely someone has written a nice, accurate article on blueprint reading.Hmmm, if not, maybe someone from WeldingWeb should write such an article and keep it in the "Keepers" forum.Thanks all,Scott
Reply:AWS puts the welding symbol key somewhere on their site as well as Lincoln I think.  The problems with print reading is that structural drawings will stump a boilermaker and pressure vessel drawings will have a structural fabricator scratching his head.  It is a very big subject area.  Simple foundations of orthographic projection is where to start.

Reply:If you google " orthographic projection"  There is quite a few hits on print reading.AWS   American Welding Society  has some info but is more and more restrictive...capitalism.TWI  The Welding Institute in Britain is helpful.http://www.twi.co.uk/professional/index.xtp#informationLook under Job knowledge for Welders.  The second section on weld symbols is quite detailed.  Symbols are quite universal as are prints.  I worked with a Russian who had a calculator size translator he had to use all the time.  He had not problem building stuff from prints however.
