• During the transition among welding machines (4 units in total) the body is rotated and the mouth of the welding is fed by the operator manually. These can lead to wrongly welding (Human).
• Welding machines may have problems (Machine).
After the welding process, CBS that provides inserting the seal into the body is assembled with the help of the welding. CBS welding machine may also be problematic (Machine). It is then subjected to washing process. Then, the body is put in the oven by setting bitumen to its five sides in order. The purpose of this process is to provide insulation. Here;
• Turning operation of the bodies while the transition between the ovens is performed by operators, which can cause deformation (Human).
• Since the turning operation is done mechanically, the body may drop suddenly and harshly onto the conveyor (Mechanical).
• At the end of the operation, the bodies are carried to the work-in-process inventory.
The bodies are still hot and overlapped and this increases the likelihood of deformation
(Methods).
