  1. Anglicky v odborných předmětech"Support ofteachingtechnicalsubjects in English“ Tutorial: Engineering technology Topic: Markingofwelds on drawings Prepared by: Ing. Josef Martinák st. Projekt Anglicky v odborných předmětech, CZ.1.07/1.3.09/04.0002 je spolufinancován Evropským sociálním fondem a státním rozpočtem České republiky.

  2. Marking of welds on drawings

  3. Marking of welds on drawings ČSN EN 22553

  4. Basic types of welds in accordance to cross section

  5. Marking 135/EN ISO 58179 • Left of the mark – main weld’s dimension • Right of the mark – weld length dimension

  6. Size of corner welds

  7. Marking of butt weld • Example: • a 4 ⊿ 40 x 50 (500) • a = weld thickness • 4 = weld size (4 mm) • ⊿ = marking • 40 = number of welds (seams) • 50 = length of welds (50 mm) • (500) = gap between welds

  8. Preparation of weld connections ČSN EN ISO 9692-1

  9. Welding location ČSN EN ISO 6947

  10. Description of multiple layer weld

  11. Advantages of welding • Weld can have arbitrary shape • Weld joint is dismountable • Disadvantage of welding • For some metals welding is difficult

  12. Used literature • DILLINGER, Josef. A KOL. Moderní strojírenství pro školu i praxi. 1. Praha: Europa-Sobotáles, 2007. ISBN 978-80-86706-19-1. • M. HLUCHÝ, J. KOLOUCH, R. PAŇÁK. Strojírenská technologie II
