=simulation for welded products
Welding is (compared to casting / machining) a fast and profitable method to build complex machines.
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
- failure analysis
- FOSTA: www.Stahlforschung.de
- "miner defects"
- SINTAP: Structural Integrity Assessment Procedures for European Industry
