The first papers on the activating flux application appeared already in 1950’s and 1960’s, but the interest for this welding process has been activated again in the last ten years 1, 2 . In order to increase the efficiency and productivity of TIG process, a variant of process with the activating flux is applied (ATIG). With the presence of the activating flux and high temperature, the value of ...

Gas tungsten arc welding (GTAW) is important in those manufacturing where it significant to control the mechanical and metallurgical characteristics its weld bead geometry. This work has been committed study influence of oxide fluxes on 4 mm thick 304 austenitic stainless steel plates. The Al2O3 TiO2 were used as an flux powder form are mixed with acetone. prepared mixture applied plate without...

This paper presents a numerical and infrared experimental study of thermal and grain growth behavior during argon tungsten arc welding of 443 stainless steel. A 3D finite element model was proposed to simulate the welding process. The simulations were carried out via the Ansys Parametric Design Language (APDL) available in the finite-element code, ANSYS. To validate the simulation accuracy, a s...

The present investigation uses arc voltages, current, welding speed, wires feed rate and nozzle-to-plate distance as process parameters. Two level full factorial a technique has been used for experiment design. Multiple regression analysis has been used to develop a mathematical model to predict weld width using a single wire Submerged arc welding depositing bead-on-plate welds on 12mm plate. A...

Plates of 3–5 mm in thickness were extracted from an AZ91D ingot and then butt joints of the plates were produced using tungsten inert gas (TIG) welding method. The TIG arc was also used to deposit welding beads on some of the thin plates. No cracking was found in the butt joints. However, hot cracking was always observed to propagate from the heat affected zone (HAZ) under the welding bead int...

This study involves the validating of thermal analysis during TIG Arc welding 1.4418 steel using finite element analyses (FEA) with experimental approaches. 3D heat transfer simulation stainless arc is implemented ABAQUS software (6.14, Inc., Johnston, RI, USA), based on non-uniform Goldak’s Gaussian flux distribution, additional DFLUX subroutine written in FORTRAN (Formula Translation). The in...

Submerged arc welding process is usually employed for welding of thick workpieces. Quality of submerged arc welded components depends on various factors. Selection of appropriate process parameters for joining metallic components is needed to obtain sound weldment. Many researchers carried out investigations to find out appropriate process conditions to obtain quality submerged arc welded compo...
