Abstract
One of the questions that is still controversial in welding is the determination of the fusion efficiency in welded joints; there are different equations in literature which provides distinct results. In the present work, the fusion efficiency was calculated by different equations available in the literature and the results compared using Box-Behnken design of experiment. It sought to study the influence of welding parameters as wire-feed speed, arc voltage, and welding speed in the calculated values, with the aim to better understand the variables influenced in melting efficiency results through the contour plots. The evaluated joint geometries were bead on plate and fillet T-joint. Three equations were used to fusion efficiency determination and comparison, showing significant differences among results and allowing a better understanding of heat flow difference between the joints. Also, it was determined the welding parameters influence in melted area and bead width geometry.
