Simulation of Weld Bead Geometry in GTA Welded Duplex Stainless Steel (DSS) [PDF]

open access: yesScholarly Research Exchange, 2009
Temperature analysis of GTA welding of Duplex Stainless Steel material (2205) is simulated using ANSYS software by finite element technique taking in account the characteristics and advantage of GTAW than other sources. A travel heat source combined with body loads was designed by analyzing thermal physical parameters, latent heat of fusion of material.

Influence of Weld Bead Geometry on Thermal Deformation in Laser Micro-Welding

open access: yesProcedia CIRP, 2013
AbstractIn this study, the thermal deformation of thin stainless steel sheet was investigated in the bead-on-plate welding by using a single- mode fiber laser with a Galvano scanning system. The numerical simulation was developed to calculate the temperature and stress fields, and its deformation characteristics were discussed.

Analysis of the combined effects of preheating and welding wire feed rates on the FCAW bead geometric characteristics of 1020 steel using fuzzy logic-based prediction models

open access: yesJournal of the Mechanical Behavior of Materials
Single weld beads were deposited on a steel plate using three different welding wire feed rates (slow, medium, and fast). The samples were preheated before welding at three different temperatures (100, 150, and 200°C).

Effect of welding gas mixtures on weld material and bead geometry

open access: yesIOP Conference Series: Materials Science and Engineering
Abstract Shielding gas is an essential parameter in welding processes, serves to shield the molten material from the atmosphere and external contaminations while providing a stable electric-arc pathway during the process, thus influencing the quality of the weld bead and several other aspects of the process.

Welding polarity effects on weld spatters and bead geometry of hyperbaric dry GMAW

open access: yesChinese Journal of Mechanical Engineering, 2015
Welding polarity has influence on welding stability to some extent, but the specific relationship between welding polarity and weld quality has not been found, especially under the hyperbaric environment. Based on a hyperbaric dry welding experiment system, gas metal arc welding(GMAW) experiments with direct current electrode positive(DCEP) and direct ...

EFFECTS OF WELDING CURRENT AND ARC VOLTAGE ON FCAW WELD BEAD GEOMETRY

open access: yesInternational Journal of Research in Engineering and Technology, 2015
Flux cored arc welding(FCAW) process is characterized with its high deposition rate and productivity. Control of the operating parameters in FCAW is essential to obtain high production rates and good quality welds. Bead on plate welds were carried out on mild steel plates to study the influence of welding current and arc voltage on weld bead geometry ...
