Optimization of the FCAW process by weld bead geometry analysis
The flux cored arc welding process has grown in use in recent times as a function of its characteristics of high rate of deposition, associated with suitable mechanical properties in the welded joint. However, many aspects still remain obscure in regard to greater utilization of this process. As a result, the intention of this work is the analysis and optimization of the voltage, wire feed speed and contact tip part distance welding parameters, in a process using tubular wire with shielding gas, on the penetration and convex index of the weld. By means of statistical techniques, a mathematical model was developed with subsequent optimization of the responses. Based on the results obtained, the strong influence of the wire feed speed on the process was seen, followed by the voltage and, with less intensity, the contact tip to workpiece distance (CTWD). Statistical analyses indicated that the best condition for the parameters analysed was obtained with voltage values between 32 and 34 V, associated with a wire feed speed of 12 m/min and a CTWD of 20 mm. On the other hand, tensions at around 36 V caused surface defects that prejudiced the quality of the weld. Later tests showed an acceptable forecast of the results of the mathematical models when compared to the actual results.
