Effect of Using Different Welding Currents and Distributed Heat Fluxes on the Geometrical Weld Bead Characteristics

Abstract

The goal of the current work is to experimentally investigate how various currents and dispersed heat fluxes affect
the geometrical weld bead form characteristic of low carbon steel that has been fused utilizing a particular kind of
fusion welding method. Designs for butt welded joints were created by welding a sheet of 4 mm thickness in a
single pass at various input parameters (welding voltage and welding current). In order to ascertain its thermal
influence on the welded bead joint geometry in terms of bead geometric characteristics (weld penetration, weld
bead width, weld bead height, and reinforcement) and shape factors (weld penetration shape factor and Weld
reinforcement shape factor), distributed heat flux and welding velocity were computed based on these factors.
Increasing the welding current was discovered to
