| dc.description.abstract | This study aims to analyze the effect of water, oil, and air cooling methods
on the mechanical properties and microstructure of SMAW welding results on ST
37 steel material. Three types of tests were conducted, namely tensile tests,
Vickers hardness tests, and microstructure tests. The results showed that the
cooling medium significantly affected the tensile strength, hardness, and
microstructure shape. Cooling using oil provided the highest tensile strength
424,19 N/mm², while cooling using water produced the highest hardness 179 HV.
The microstructures formed varied from pearlite, bainite to martensite, depending
on the cooling medium used. This study contributes to the optimization of welding
processes in industrial applications. | en_US |
