Numerical Analysis of the Influence of Electrode Inclination on Temperature Distribution during GMAW Overlaying

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In the work, an analysis of the influence of electrode inclination on the distribution of temperature in the weld overlaying has been conducted. In the analytical description of the temperature field, a volumetric heat source model with an inclined axis with respect to the direction of surfacing was adopted.

Computational and Mathematical Model with Phase Change and Metal Addition Applied to GMAW

Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017
This work presents a 3D computational/mathematical model to solve the heat diffusion equation with phase change, considering metal addition, complex geometry, and thermal properties varying with temperature. The finite volume method was used and the computational code was implemented in C++, using a Borland compiler.
