“…Menurut dokumentasi dan penelitian arkeologi, ada banyak cara yang dapat dilakukan untuk memproduksi pedang secara konvensional, misalnya teknik pembuatan Katana (pedang Samurai) Jepang dengan material baja karbon [7], sementara di bagian Timur terdapat pembuatan pedang dengan Teknik Damaskus yang dikenal dengan nama Teknik Welded Damaskus [8].…”

ABSTRAKTanto merupakan senjata tajam yang berasal dari Jepang dan merupakan senjata kedua bagi para Samurai di Jepang. Tanto biasa terbuat dari baja karbon menengah hingga baja karbon tinggi yang. Material baja yang digunakan untuk pembuatan Tanto dalam penelitian ini adalah baja AISI seri O1 karena memiliki karakteristik sifat mampu bentuk yang baik serat dapat dikuatkan melalui proses heat treatment. Material baja ini dibuat dengan proses tempa lipat dengan variasi tempa empat lipatan dan satu lipatan. Pembuatan Tanto dan spesimen uji dilakukan dengan proses tempa lipat secara konvensional menggunakan tungku arang, dengan temperatur tempa rata-rata yaitu ±1200oC, kemudian dilanjutkan dengan quenching pada temperatur ± 850oC, serta tempering pada temperatur ±250oC. Penelitian ditujukan untuk mengetahui pengaruh dari proses tempa empat lipatan dan tempa satu lipatan terhadap sifat mekanik, yaitu kekerasan dan kekuatan impak serta untuk melihat perubahan pada struktur mikro. Hasil pengujian menunjukkan bahwa nilai kekerasan paling tinggi sebesar41HRC yang dimiliki oleh pada raw material, ,sedangkan nilai impak paling tinggi sebesar 224,02 Joule/cm² ayng dicapai oleh material dengan proses tempa empat lipatan, Fasa akhir yang ditemukan pada baja tempa empat lipatan adalah bainit dan martensit, sementara perlit dan ferit ditemukan pada baja satu lipatan, dan lath martensit ditemukan pada pada raw material Kata kunci: Pisau Tanto, Tempa lipat ,Quenching, Tempering, Uji Impak ABSTRACT Tanto is a sharp weapon originating from Japan and is the second weapon for Samurai in Japan. Tanto is usually made of medium carbon steel to high carbon steel. The material which is used in this research is AISI O1 series steel because of its high ability to be formed and also can be made tough through a heat treatment process. This steel is made by folding forge process, with variation in number of folding, which is 4 folds and 1 fold. The making of Tanto and test specimens was carried out by conventional fold forging processes by using a charcoal furnace, with an average forging temperature at ± 1200oC, continue with quenching at ± 850oC, and tempering at ± 250oC. The research is carried out in order to determine the effect of the four-folds forging and one-fold forging to the mechanical behavior, which are hardness and impact strength, and also to see change in its micro structure. The test that have been carried out shows that the highest hardness value of 41 HRC owned by raw material, while the highest impact value of 224.02 Joules / cm² obtained by material with four layer forging process. Final phases that found in the four-fold forged steel are bainite and martensite, pearlite and ferrite found in one-fold forged steel. and lath martensite in found in the raw material. Keywords: Tanto Knife, Folding Forging, Quenching, Tempering, Testing, Impact Tests

“…Solid state welding methods include one of the oldest welding methods in the world, such as forging [4]. The katana swords used by the ancient Japanese Samurai were also produced with forging welding (forged steel) [5]. Pressure and/or heat are used in solid state welds, but the effect of heat does not melt the parts and softens them [6].…”

Lightweight and durable materials such as aluminum alloys are widely used in sectors such as defense industry, aerospace industry, automotive industry, and high-speed train manufacturing. Some of these materials cannot be welded by conventional methods due to their high thermal conductivity and low melting point. In welding processes, the material properties are expected to be as close as possible to base material. Friction stir welding (FSW) is a joining method that provides welding below the melting point of materials that cannot be welded by conventional methods or where the welding process causes the mechanical structure of the material to deteriorate. In this study, FSW application, advantages and disadvantages and usage areas of friction stir welding were examined.

Welding by Hot Forging of Two Carbon Steels for the Manufacture of Spanish and Japanese Weapons

Abstract: The technologies of manufacture of medieval and modern weapons in Spain and Japan, keep a very remarkable similarity. Through different paths and sensitivities, the use of steel was achieved with a common idea: hardness, resistance and toughness; all combined in a single set of steel.
