Effect of Mig Welding Input Process Parameters on Weld Bead Geometry on Hsla Steel

The various welding parameters such as welding speed, voltage and gas flow rate were varied on HSLA steel and the effects of these parameters on weld bead geometry such as penetration, width & height have been studied. Mathematical equations have been developed using factorial technique. And the result of various effects are shown in tables. (Numerical Values). INTRODUCTION Wide variety of stee...

Influence of shielding gas composition on weld profile in pulsed Nd:YAG laser welding of low carbon steel

Weld area and weld depth/width ratio can be considered to be of the most important geometrical factors in pulsed laser welding. The effects of carbon dioxide and oxygen additions to the argon shielding gas on the weld properties in pulsed laser welding of low carbon steel is investigated. Presence of carbon dioxide and oxygen up to 10 and 15 percent respectively decreases the weld geometrical f...

Influence of Flux Cored Arc Welding Parameters on the Weld Bead Geometry in 316l Stainless Steel Claddings Deposited on Aisi 1020 Carbon Steel Plates

In recent years, stainless steel cladding applications have increased in industrial environments due to this process allows anti-corrosive surfaces be produced from low cost materials, such as carbon steel or low alloy steels. However, to ensure the final quality of the claddings, it is important to know the welding parameters’ effects on the process outputs. This contributes to an appropriate ...

Numerical simulation of the dynamic characteristics of weld pool geometry with step-changes of welding parameters

Abstract The gas tungsten arc welding process is an uncertain nonlinear multivariable system. In order to control the welding process, the nonlinear dynamic relationship between the weld pool geometry reflecting the weld quality and the welding parameters must be developed. A three-dimensional numerical model is developed to investigate the dynamic characteristics of the weld pool geometry when...
