RESEARCH ON THE COMPARATIVE ANALYSIS OF PROCEDURAL DIFFERENCES BETWEEN MANUAL GTAW WELDING AND AN 8-AXIS ADAPTIVE ROBOTIC SYSTEM GTAW WELDING ON SPECIFIC SAMPLES

Abstract

The objective of the paper is concerning an 8 axis Adaptive Robotic System GTAW welding on 3,2 mm thickness test piece, base material stainless steel 304L with 1,2 mm diameter ER308L as filler material. The paper determines from the results obtained on test pieces, the current comparative analysis between the manual GTAW welding old process and the 8 axis robot GTAW welding new process. After the welding of the test parts, the application of the 8 axis robot GTAW welding new process requires a major initial investment which determines the decrease of the welding time by 50%, the decrease of the total parts execution time by 25% and the decrease of argon consumption by 44%.
