By cladding, one refers deposition of a relatively thick metal layer onto a cheap grade base material to protect it against severe abrasive / erosive /corrosive working condition. Enhancing hardness of a surface through cladding is given the name hardfacing. In this investigation, FCAW (Flux-Cored Arc Welding) cladding is performed using fluxed-core duplex stainless steel electrode onto low alloy steel substrate using 100% CO2 as the shielding gas. Different values of welding current and welding voltage were selected for the experiment in such a way that 3 sets of constant heat input were maintained. Welding torch travel speed was kept constant throughout the experiment. Hardness test results revealed much improved hardness of the clad part compared to that of the base material. Only slight change in hardness can be noticed under varying weld current when heat input remains the same.Keywords

Cladding is usually done to protect a surface from corrosive or erosive wearing. Better cladding demands optimum weld bead geometry that should have less penetration giving less dilution. Heat input plays a vital role to produce a weld bead profile characterized by its width, reinforcement and depth of penetration and some shape factors like RFF (reinforcement form factor) and PSF (penetration shape factor). In the present case, 316 austenitic stainless steel bead was produced on E250 low alloy steel by GMAW process using only carbon dioxide as the shielding gas. Nine bead-on-plate samples were produced with nine different heat inputs. Welding voltage was kept constant. Experiments were replicated twice for achieving more reliability. Experimental results showed that width, height and depth of weld bead got lager with larger heat input on the whole. On the contrary, shape factors like reinforcement form factor and penetration shape factor tend to become smaller with larger heat input. Linear regression analysis is carried out to evaluate the relation between heat input and different bead profile components as well as shape factors. ANOVA table suggests the equations proposed by regression analysis are explainable and significant at 95% significant level.Keywords
