Abstract

Dengan adanya metode pengelasan gesek (friction welding) yang lebih banyak diaplikasikan untuk pengelasan pada logam-logam padat (solid) untuk itu penulis ingin mengetahui hasil sambungan apabila diaplikasikan untuk pengelasan pada pipa yang diklaim dapat mempersingkat waktu pengelasan. Karena pada proses pengelasan listrik biasa, para tukang las (welder) mengalami banyak sekali kesulitan sehingga memerlukan waktu yang lama dalam pengelasan pipa. Berdasarkan percobaan pengelasan gesek (friction welding) yang pernah dilakukan, didapatkan hasil pengelasan pipa yang mempunyai banyak sekali jariasi pada akar las (root), sehingga akan memberikan kontribusi terhadap penurunan aliran massa fluida (mass flow) yang mengalir didalam pipa. Dalam penelitian ini akan disimulasikan dengan menggunakan software yang berbasis Computational Fluid Dynamics (CFD), untuk menganalisa mass flow yang terjadi didalam pipa yang di las dengan pengelasan gesek. Dari hasil simulasi yang Ielah dilakukan terlihat bahwa terjadi penurunan mass flow yaitu kurang dari 1 %

With the friction welding method being more widely applied for welding on solid metals, the author wants to know the results of the connection when applied to welding on pipes which is claimed to shorten welding time. Because in the ordinary electric welding process, welders experience many difficulties so that it takes a long time to weld pipes. Based on friction welding experiments that have been carried out, the results of pipe welding have been obtained which have a lot of fingers at the root of the weld, so that it will contribute to reducing the mass flow of fluid flowing in the pipe. In this study, a simulation will be carried out using software based on Computational Fluid Dynamics (CFD), to analyze the mass flow that occurs in pipes welded with friction welding. From the simulation results that have been carried out, it can be seen that there is a decrease in mass flow of less than 1%
