... of this chapter. At the time this chapter was written, bridging the gap between Solid Modeling and FEA/FDA casting simulation programs is one of the main challenges for the effective use of these programs in a Concurrent Engineering environment. Most of the FEA/FDA programs require as input the transfer of Finite...

... the joints (electrical resistance) [ Messler 1999 ; O’Brien 1991 ]. Filler metals may be used to supplement the fusion process for components of similar composition, as, for example, when the joint gap is wide and, possibly, of variable width. In that situation, the filler is often chosen to have...

Center buckling can be minimized by optimizing the roll gap. A tight gap may support transversal elongation and increase buckling. Another defect that may appear...

In that situation, the filler is often chosen to have a marginally lower melting point than the components in order to help ensure that it completely melts. Characteristic features of welding include: Welding invariably involves a heating...
