چکیده مقاله
Turbulent friction welding FSW is a growing technology in the manufacturing industry because of its many innovations, including the welding of lightweight materials such as aluminum and magnesium This process has recently been implemented for the connection of thermoplastics Turbulent friction welding is a solid state welding process that has a non consumable rotating tool consisting of two parts, a comb and a pin The process tool generates friction and heat by rotating and entering two sheets that are firmly placed next to each other, creating a bond In this process, the connection is made by the rotating tool and the existing pin on its head Turbulent friction welding has many advantages over conventional melting welding methods due to its low inlet temperatureand lack of melting and re freezing of materials In this paper, the effect of linear velocity changes of the tool on the tensile strength of welded polypropylene parts in this method is investigated After welding the parts and their tensile test, it was found that at low rotational speeds, the welding strength decreases with increasing linear velocity of the tool However, this is not the case at high linear velocities, and the highest yield limit recorded at the linear velocity is 25 mm / min, which is achieved at a rotational speed of 400 rev / min, and its value is 11 7 MPa, which is 80% of the yield limit of the base material
