At the joining of non-removable plastic parts, the methods such as friction welding, friction-stir welding, ultra-sonic welding, chemical joining, hot-plate welding use. Rotary friction welding, which is one of the friction welding methods, is generally used for joining the filter parts of water treatment devices. After rotating friction welding of the filter parts, semi-melted agglomerations are formed in the inner parts. To prevent semi-melted accumulation, weld joint profile design was developed in the ABAQUS program in the previous study. In this study injection molds had been produced and production according to weld joint profile design. The taken plastic presses were welded with the friction welding machine and the joint was controled and compared. It is seen that the semi-melted agglomeration was successfully confined. By performing Taguchi experimental method and ANOVA analysis on friction welding machine parameters the optimum pressure conditions were determined, aimed to carry out static and dynamic tests according to NSF standards and field tests by producing 1500 pilots product and it has been put into use. The lifetime of the developed filter depends on the material which was used in manufacture. In the next study, it is aimed to improve the lifetime of the developed filters.

When welding ultra-fine-grained metals using conventional methods, the microstructure in the joint area is degraded (mainly due to recrystallization) in the heat-affected zone and a significant deterioration of mechanical properties, including joint strength. The aim of the research presented in this article was to identify the possibility of obtaining joints with strength close to initial material using friction welding of metal materials with ultra-fine grain. For this purpose, UFG (ultra-fine-grained) material was produced from technically pure M1Ez4 copper using a hybrid SPD (severe plastic deformation) process. The welding process was carried out on a machine with a prototype design that allows minimizing the welding time, while generating high force. The process parameters used on the prototype machine resulted in an increase in the hardness of the material by 4% in the joint area. The strength of the joint compared to the base material decreased slightly by 2%. The tests carried out proved that, using appropriate process parameters, it is possible to obtain a UFG metal joint without a decrease in its mechanical strength.
