**u2.03.05** User manual for numerical welding simulation
==========================================================================

**Summary**

The objective of this document is to provide the information necessary for a user to perform multi-pass welding calculations with*Code_Aster*. It is a methodological guide on the tools available and the good practices to be put in place to conduct a quality study in numerical welding simulation.

The various tips given to the user come essentially from feedback from three studies:


*A chamfered 316L pipe welded by the TIG process, with filler metal in thirteen passes (sheet CEA/EDF 3488); the first 2 passes of this example constitute a test case*Code_Aster* [:external:ref:`V7.42.100 <V7.42.100>`]);


*A 316L chamfered plate welded by the TIG process, with filler metal in two welding passes (sheet CEA/EDF 2425); the various command files associated with this study are stored in the*Code_Aster* study base (SERVICE/BDD Studies);


* A non-chamfered 316L plate, with the creation of a fusion line by the TIG process, but without a filler metal (thesis INSA from Lyon by L. Depradeux defended in 2004).
