Abstract
This study focuses mainly on studying the effect of a range of welding parameters on the weld quality of 304L stainless steel welded bars, using ER-308L filler wire. All welding experiments carried out in this work were conducted at the Welding Lab, The University of Tripoli, Libya. The welding process is performed with the use of Gas Tungsten Arc semi-automatic welding manner. The effects of different welding parameter (welding current, welding speed, and the flow rate of shielding gas) on the quality of welding joint (welding bead width, weld penetration and heat affected zone(HAZ))wereinvestigated. The optimum welding conditions based on the analysis of the data from the different experiments for tensile and hardness tests of the welded sampleswere established.A modeling approach; named Taguchi method, which examines the effect of the measured weld bead width, welding penetration and the size of heat affected zone(HAZ) region on the weld quality was used. The modeling results compared with the data from the mechanical properties of the welded samples and investigate whether there is a link between the modeling approach and the experimental work.The results showthata good quality welding joints of 304L stainless steel, with a welding current of 185 A, welding speed of 135 mm/min and gas flow rate of 10 L/min should be used. These combination of welding conditions provided the best tensile and hardness mechanical properties for the welded samples, and find a reasonable agreements with the Taguchi modeling approach.
