Abstract
The necessity to develop a welding holdfast to avoid warping of the plates during a multiple passes welding process, caused that the computational analysis was approached in order to obtain the necessary parameters. The welding processes used as well as their parameters and samples sizes were defined by Welding Process Specifications (EPS). The finite element study was carried out through a transient analysis of the stainless steel AISI304, using its temperature-dependent properties. Birth and death functions were applied to represent the deposition of the addition metal through a Gaussian heat source.
