In dishwashers, the washing process is realized by spraying the water received from the water delivery line onto the dishes by means of spray arms. Water is sprayed onto the items placed in the rack by means of the spray arms. In order to spray water homogeneously onto all the items in the dishwasher, the spray arms rotate around themselves at different RPMs and speeds. Thus, the water is enabled to be delivered onto the items at an angle. Water can reach a larger area as the density and the speed thereof increase. It is highly important to deliver the water to the edge regions of the machine. While the dishes placed in the central region of the rack are generally washed more effectively, the dishes placed near the edges are not washed properly due to insufficient water delivery. The positioning of the nozzles on the spray arm is generally determined by taking such situations into account so as to aim to improve the washing performance. Spray arms may be manufactured as a single piece, but generally the lower and upper parts are manufactured separately and the lower and upper parts are joined together by welding. Thus, ease of production is provided. However, in order to provide a welding line, the nozzles must be positioned closer to the central region of the spray arm. The joint line formed along the outermost edge of the spray arm makes the placement of the nozzles difficult. This prevents the water delivery from the ends of the spray arm. In the state of the art, there are embodiments where the joint line is formed through the center of the spray arm, and the end nozzles are intersected along the joint line. However, this also results in manufacturing challenges.
