Abstract
In this work, investigations on characteristics of weld of AISI stainless steel using DOE methodology with and without magnetic interaction in microplasma welding studied. Three welding parameters i.e. magnetic field strength, welding current and plasma gas flow rate used to conduct the experiment. The objective of this paper was to study the effect of magnetic field on the weld quality and geometry when the field is applied longitudinal to the electrode travel i.e. the field lines are perpendicular to the electrode travel. It was noticed from experimental results that with the interaction of magnetic field to the welding arc, penetration decreases.
