Title : Analysis Corrosion Resistance and Flexural Stress of AISI 304L using ER308L in GTAW with Currents Variations

Abstract :

The joining of metal material for pressurized tanks generally uses gas tungsten arc welding (GTAW) with the selected content, which has the character of being resistant to Corrosion and bending, AISI 304 L is often used as material for the tank. Still, a weakness that is often experienced by the content. Starts from Corrosion that can be caused by metals, environmental factors, and factors in the process of making tanks. With the various factors that influence the above, this research was conducted to determine the extent of material resistance to Corrosion and flexibility after the welding of GTAW. The method used is an experimental test of the material by first checking the content using ARL 3460 Optical Emission Spectrometer (OES). NDT-liquid dye penetrant to determine weld defects, then bending test to determine post-welding flexibility and corrosion resistance tests using the Ferric Chloride Pitting Method Test. The results showed that at 70 A current, there were no cracks that occurred after the face bend and root bend tests, but at 100A and 130A currents, the break occurred along with the specimens in the root bend test. The greatest bending stress at 130A and the weight loss of corrosion test results occur in samples with 70A welding currents
