TLDR
In this article, a new mathematical description of a heat-source has been formed to represent the common in-service welding process, i.e. vertical-up and vertical-down manual metal arc (MMA) welding with hydrogen controlled electrodes.About:

Effect of weave frequency and amplitude on temperature field in weaving welding process
TL;DR: In this article, a coordinate transformation method is put forward to simulate the weave welding process and the temperature distribution during the welding with weaving under different weave parameters are compared and discussed. But the effect of weave frequency and weave amplitude on the temperature field is not clear.

Finite element modeling of GTA weld surfacing applied to hot-work tooling
TL;DR: In this paper, a finite element modeling of GTA weld-surfacing process using abaqus computer code is performed using temperature transients during welding, as well as deformation and residual stresses as a result of repair-weld surfacing of complex-geometry H13 tooling.

The onset of pipewall failure during "in-service" welding of gas pipelines
TL;DR: In this article, a numerical model was used to predict pipe-wall failure for circumferential fillet and longitudinal welds using a thermo-elastic plastic analysis, and the prediction of burn-through has been achieved using thermoelastoplastic model.

Three-dimensional finite element analysis of temperature and stress distributions for in-service welding process
Chaowen Li,Yong Wang +1 more
TL;DR: In this paper, a 3D numerical model was established to simulate a single bead-on-plate specimen to study the influence of flowing water on the temperature field and stress distributions of in-service welding, model predictions have been compared against data generated by welding without flowing water.

A new finite element model for welding heat sources
TL;DR: In this article, a double ellipsoidal geometry is proposed to model both shallow penetration arc welding processes and the deeper penetration laser and electron beam processes, which can be easily changed to handle non-axisymmetric cases such as strip electrodes or dissimilar metal joining.

Models aid pipeline-repair welding procedure
J.F. Kiefner,R.D. Fischer +1 more
TL;DR: Improved welding procedures to repair a pressurized pipeline can now be designed with the use of computer models of the welding process using the Battelle Columbus Division from research sponsored by several major petroleum liquids and natural gas pipeline operating companies as mentioned in this paper.
