Popis:	This paper presents an approach for a weld connection modeling in the finite element method using the method of La-grange multipliers. The key issue is to fulfil contact conditions of the weld connection with the possibility to use it for connection of non-conforming meshes. That is why a general node-to-segment (NTS) algorithm which enables to define the connection between nonconforming meshes is used.
