- Abstract
- The welding technology of a pleated type metallic filter is an important factor when considering influences on filter quality. In this study, micropulse gas tungsten arc welding (GTAW) was used to weld the pleated type metallic filter. The micropulse GTAW is a multivariate process with a variety of welding parameters that work in pairs, and parameter optimization is necessary in order to achieve high welding quality. For this study, the micropulse GTAW process parameters are optimized using response surface analysis in order to produce high-quality pleated type metallic filter welds. The process parameter values found through optimization are as follows: a pulse current of 20.34 A, a base current of 5.8 A, a pulse duty of 32.01%, a frequency of 10.34 Hz, and a welding speed of 0.21 cm/s. Using the hydraulic pressure estimation model, the pressure was estimated to be 155.8 mmH(2)O. The welding experiment was performed under optimal conditions in order to evaluate the efficiency of the hydraulic pressure estimation model. The actual hydraulic pressure was 152 mmH(2)O, which confirms the performance reliability of the hydraulic pressure estimation model.
