In this study, a three-dimensional (3D)finite elementmodel is developed to investigate thermally induced stress field during hybrid laser–gas tungsten arc welding (GTAW) process. In the hybridwelding case, we focus on the GTAWprocess sharing commonmolten poolwith laser beam and playing an augment role in thehybridweldingsystem.Anexperiment-based thermalanalysis isperformedtoobtain the temperatu...

The article presents results of comparative A-TIG welding tests involving selected unalloyed and fine-grained steels, as well high-strength steel WELDOX 1300 austenitic stainless AISI 304L. involved the use single ingredient activated fluxes (Cr2O3, TiO2, SiO2, Fe2O3, NaF, AlF3). In cases carbon low-alloy revealed that greatest increase in penetration depth was observed steels which had been de...

Tungsten Inert Gas (TIG) welding is otherwise known as the Arc soldering (GTAW) process which when significant levels of weld quality or high precision are required, to represent an advanced arc process. However impact factors on this form important for its produced in single-pass welding. In investigation, autogenous was performed a carbon mild steel plate with four parametric variables. High ...

The prediction of the weld bead geometry parameters is an important aspect welding processes due to it related strength welded joint. This research focuses on using statistical design techniques and a deep learning neural network predict shape shielded metal arc (SMAW), inert gas (MIG), tungsten (TIG) processes. With techniques, experiments were carried out obtain data for generating regression...
