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...
متن کاملSelection of Arc Welding Parameters of Micro Alloyed Hsla Steel
Like all steel types, HSLA requires a definition and strict practical adherence to welding parameters in order to achieve the required weld quality. Different sources offer a varying array of welding parameters. Although their hierarchical importance can be disputed, their principal definition and practical adherence are prerequisites for the quality of welded joints 1,2 . The analysis of earli...
متن کاملTransformation Plasticity in Steel Weld Metals
Professor Ulrich Dilthey’s passion for the science and technology of joining processes is amply reflected in the enormous archive of published work which will forever serve the community. It is a pleasure therefore to be able to present this small story as a tribute to someone who has been a scholar, a gentleman and a leader in this most difficult of subjects. The matter of our everyday world i...
متن کاملSize distribution of oxides and toughness of steel weld metals
The trend in strong weld metals is towards microstructures dominated by low carbon martensite. The role of oxide particles introduced into the metal during welding then becomes uncertain. The particles do not seem to affect the nucleation or growth of martensite. This is probably because this phase forms at relatively large driving forces and therefore does not rely on heterogeneous nucleation ...
متن کاملInfluence of Cu and Ni on the Microstructure and Mechanical Properties of an HSLA Steel
In this research the role of alloying elements on the microstructure and mechanical properties of an as cast and hot rolled high strength low alloy (HSLA) steel was studied. Different compositions with different amount of copper in the presence of nickel, hot rolled and quenched in oil. Tensile test, hardness test, scanning electron microscope (SEM) and optical microscope (OM) were used to eval...
