Pengaruh Variasi Tekanan Gesek Terhadap Distribusi Temperatur, Struktur Mikro, Kekerasan dan Uji Tarik Pada Pengelasan Continuous Drive Friction Welding Silinder Pejal Logam Beda Jenis Baja St 60 dan Stainless Steel 304

Many welding techniques are carried out in the construction of buildings
and on vehicles. The process of friction welding is a fairly new welding method.
Conventional rotating friction welding only requires one part to be joined by
rotating it. The CDFW (Continuous Drive Friction Welding) is friction welding
where one component is stationary with the component rotating at a constant
speed. Parameters of friction pressure, forging pressure, friction time and forging
time. Therefore, a study was conducted to determine the effect of variations in
friction welding friction pressure. by adding the temperature distribution in order
to find out the optimal pressure in friction welding.
The purpose of this research is to find the optimal variation of friction
pressure in friction welding with the method of Continuous Drive Friction
Welding (CDFW). This study uses materials of different types with variations in
friction pressure. The use of temperature distribution in this study was used
because in previous studies it was still not widely used.
The results of the study consisted of different variations of friction
pressure, by adding to the temperature distribution that occurred during the
welding test with tensile testing, microstructure testing and hardness testing. The
results of the maximum temperature distribution are at the variation of the friction
pressure of 50 MPa with these results showing that the friction pressure affects the
temperature distribution in each variation. The results of the tensile test show that
the pressure variation of 70 MPa gets a maximum tensile strength value of 567.07
MPa with the results of the tensile test showing brittle fracture in the joint area.
The results of microstructure testing showed that microstructure reactilization
occurred in the joint area.The hardness test results obtained at the variation of the
friction pressure of 50 MPa get the highest hardness value with a value of 455
VHN.
