Internal stiffener automatic welding process null of cylindrical husks

摘要

PURPOSE: To improve the welding quality of a joint and improve the welding efficiency by automatizing the T joint welding operation of an internal surface reinforcing material of a cylinder shell, etc. ;CONSTITUTION: An axial line of a cylinder shell 1 that its diameter is large comparing to its height and circular circumferential reinforcing materials 2 are arranged in its internal surface is made vertically and its lower end periphery is supported with plural driving rotation rollers 5 and following rotation rollers 6, a welding manipulator 11 is installed inside the cylinder shell 1, while rotating more than two rotation rollers 5 around the axial line within the horizontal plane, and the T joint of the reinforcing material 2 is automatically welded by using the welding manipulator 11.;COPYRIGHT: (C)1995,JPO
