Abstract

The railway manufacturing industry is critical for developing efficient and sustainable mass transportation systems. PT. Industri Kereta Api (Persero) (PT. INKA), a leading company in Indonesia, faces significant challenges due to deformation caused by residual stress during welding processes. This study reviews various reforming techniques implemented by PT. INKA to address these issues. The objectives include evaluating the effectiveness of these techniques and identifying potential improvements. Methods such as post-weld heat treatment (PWHT), controlled cooling, and mechanical tools are analyzed for their ability to mitigate deformation. The study demonstrates that PWHT reduces residual stress and improves material quality by homogenizing the microstructure. Controlled cooling techniques effectively reduce distortion by allowing even temperature distribution during the cooling process. Mechanical tools provide nonthermal methods to stabilize and control deformation, significantly reducing distortion levels. Despite the success of these techniques, PT. INKA faces challenges related to process control and skill variance among workers. The study concludes that while reforming techniques significantly enhance the structural integrity and performance of railway components, consistent implementation and clear guidelines are essential for future improvements. Developing new technologies, enhancing workforce training, and creating comprehensive process guidelines are recommended to maintain high standards and competitiveness in the global market.

Abstract

Steel is a metal alloy primarily composed of iron, with carbon as its main alloying material along with several other components according to specific requirements. Low carbon steel has a carbon content of 0.05-0.3% and is easily manufacturable. This type of steel is commonly used for vehicle frames and other applications. The material used in this study is Carbon Steel S355J2, classified as low carbon steel with 0.15% carbon and 1.46% manganese. Carbon Steel S355J2 is used for the underframe of freight trains by PT Industri Kereta Api Indonesia. Coating and protection are crucial due to its susceptibility to corrosion, which can damage its structure in operational railway environments. As additional data for the company and learning for the researcher, a pull-off test was conducted varying the thickness of the primer coat. The results showed that sample A (110 µm), B (150 µm), and C (200 µm) achieved adhesion strengths of 2.5 MPa, 4.5 MPa, and 5 MPa respectively. The surface roughness level of the samples was 90 - 120 µm. Based on the test results, the most suitable coating system for the UGL underframe painting project for PT Industri Kereta Api (INKA) is a primer with a thickness of 150 µm (Sample B). This thickness is not too high, yet it significantly exceeds PT INKA's minimum criteria and avoids overcoating.
