الملخص

A scientific study mainly concerned with calculating and designing a special automatic installation with mechanisms to move- in vertical plane- the automatic welder and to rotate the cylinder or tube with certain speed as well as to move it along its axis. The work contains general information and classification of welding processes and principles arc welding and description of the existing and suggested mechanisms and other calculations. It also contains an economical part.
