Abstract
Preheating is the process of heating material before welding to reduce thermal stress and prevent welding defects and distortion. This study aims to analyze the effect of variations in preheating temperature and holding time on welding defects and distortion in SS400 steel material. The preheating temperature variations tested were 55°C, 60°C, 65°C, 70°C, and 75°C, while the holding time variations were from 52 seconds to 127 seconds. The research methodology included specimen preparation, preheating, welding, measurement of welding defects using Non-Destructive Testing (NDT), and distortion analysis. Data analysis was conducted using ANOVA to determine the significant effects of the tested variables. The results showed that variations in preheating temperature and holding time significantly affected the number of welding defects and degree of distortion but did not significantly affect the size of welding defects. A preheating temperature of 65°C and a holding time of 127 seconds resulted in the minimal welding defects and distortion. This combination provides the best optimization for reducing the number of defects and distortion in the welding process of SS400 steel. This research can serve as a reference for more efficient and effective preheating parameter settings in the welding industry.
