Pengaruh Variasi Tekanan Forging Terhadap Hasil Sambungan Material Stainless Steel 304 Menggunakan Mesin Las Gesek Rotary Tegak Bar-Plate

---

Welding is a process of joining two metals with or without the process of melting the base metal. There are several types of metal that are commonly used in welding, one of which is stainless steel. The aim of this research is to determine the effect of forging pressure on the welding time of the joint in the interface area and the hardness value in the welded joint of 304 stainless steel material using a bar- plate upright rotary friction welding machine. The method used in this research: Forging pressure 0.65 MPa, forging pressure 0.7 MPa, and forging pressure 0.75 MPa. Tests used in the research: liquid penetrant test, metallography, and Vickers. The time results obtained from using a forging pressure of 0.65 MPa resulted in a time of 175 seconds, a forging pressure of 0.7 MPa of 139.7 seconds, and a forging pressure of 0.75 MPa of 81 seconds. When observing the interface area, variations in forging pressure had an effect on cracks and cavities, where at a forging pressure of 0.65 MPa, cracks and cavities were found and none were found at a forging pressure of 0.7 MPa and a forging pressure of 0.75 MPa. In hardness testing from variations in forging pressure of 0.75 MPa, the highest hardness was found in the interface area with an average roughness value of 184.23 kgf/mm². Meanwhile, the lowest hardness value in the interface area resulted from variations in forging pressure of 0.65 MPa with an average hardness value of 167.66 kgf/mm².
