=simulation for welded products

FEM simulation is a good tool to get safe, but light-weight welded constructions.

If you need a quick start / high-level finish, try our checklist:

• Most welding books and rules are mainly for manufacturing of welds
  => find special welding literature for simulation engineers (here will be a link to our list)
• Understand failure analysis of welded products (visit the links below)
  
• Required welding basics for simulation engineers:
  - Understand the needs of your welding manufacturer
  - Establish a good teamwork with the welding manufacturer (treat external like internal!)
  - Understand the preconditions and the workflow of welding-rules ( prefer IIW as the "golden standard" )
  - Do not mix the codes! => choose one and use it
  - Simulating welded products does not only require deep FEM+mat+mfg knowledge, but also good CAD practice
  - Make safer welded products
  - Make cheaper welded products
  - It is never at the end, see our way to good weld-simulation-practice : sim4w-history )
  
• Even the best simulation cannot improve a bad weld construction
  But a good weld construction can make a simulation easier / perhaps even unnecessary!
  
• "Visual" links for e-learning are easier than thick books (use strg to open link in a new window):
  - Typical weld discontinuities as sketches or photos
  - efatigue
  - failure analysis
  - FOSTA: www.Stahlforschung.de
  - "miner defects"
  - SINTAP: Structural Integrity Assessment Procedures for European Industry
  - useful_Tables

  Thanks to everybody who helped us to find and discuss these informations.
