AUTOMATIC CIRCUMFERENTIAL WELDING MACHINE

摘要

PURPOSE:To save labor and to reduce working time by providing a torch to a cylindrical body fitted to a central shaft in such a way that the position of the torch can be freely adjusted thereby enabling entire circumferential welding of a disc-shaped object to be welded. CONSTITUTION:An automatic circumferential welding machine consists of a central shaft 10, a welding machine body 4 and a fixing device which fixes perpendicularly the shaft 10 to the center 9 of a disc-shaped object 3 to be welded. Said shaft 10 is erected perpendicularly to the center 9 of the object 3. The body 14 is provided with a torch 13 to the cylindrical body 11 fitted to the shaft 10 in such a way that the position thereof can be adjusted. The object 3 is automatically welded over the entire outside circumference thereof by such device. Labor is saved and the working time is reduced.
