Abstract

A construction company produced a side-dump type trailer used to transport coal, but it suffered damage in the form of cracks in the welding joints on the floor. The weld joint uses two different materials, Bissalloy 400 and SM490YA steel. This study aims to analyze the damage and repair it using appropriate electrodes, preheating, and interpass temperature, which affect the hardness and microstructure of both materials. The hardness test results showed that the highest value reached 385 HVN. Increasing the preheat and interpass temperatures was found to decrease the material's hardness. Microstructure analysis revealed phase changes in the weld metal, including mixing of martensite phase, ferrite phase, and pearlite phase. The use of a buffer layer between dissimilar materials proved effective in reducing the risk of cracking and deformation. This research confirms the importance of selecting appropriate welding parameters to improve joint quality in materials with significant carbon equivalent differences.

Abstract

The use of welding technology in the manufacturing industry has become increasingly widespread due to its ability to enhance production effectiveness and efficiency. Stainless steel 304 is commonly used in industrial applications but is highly sensitive to weld-induced thermal expansion, making it prone to distortion. Such distortion is considered detrimental as it leads to deformation of the design, reduced dimensional accuracy, decreased mechanical strength, and increased costs for welded product repairs. To address this issue, a study was conducted using trailing heat sink-assisted welding. The Gas Metal Arc Welding (GMAW) method was applied with variations in filler electrodes (ER316LSi and ER308LSi) and welding currents (100 A and 120 A). The welding results were visually inspected and distortion was measured. The findings indicate that welding with a trailing heat sink can effectively reduce distortion, particularly at higher current levels.
