摘要： PROBLEM TO BE SOLVED: To provide a method for surely perform a butt welding of pipe by which anyone can easily set a balloon to a position away from a weld zone without being damaged, and the balloon can be made in close contact with the pipe over a long period of time. SOLUTION: The method of butt-welding pipes by using a water soluble balloon comprises: a step S1 in which, after storing in a shrunken balloon through an introducing cylinder a volatile material that gasifies by volatilization or sublimation, the introducing cylinder is blocked, with the material sealed therein; a step S2 in which the balloon with the volatile material stored is pushed into a pipe and set at a position away from a joining end; a step S3 in which the balloon is expanded with the gas generated by the volatilization of the volatile material and closely stuck to the pipe; a step S4 in which the joining ends of the pipes are abutted on each other, with the inside space substituted with an inert gas; a step S5 for welding the butted part of both pipes; and a step S6 in which the balloon is dissolved by supplying a fluid into the pipes.

摘要： PROBLEM TO BE SOLVED: To automatically copy and buff a deformed work by copying a fillet weld part in a narrow part while keeping a distance between a surface to be buffed and a buffing tool constant by a distance measuring device. SOLUTION: If an object work 14 has a deformation on a surface to be machined, a distance between the object work 14 and a buff is measured by a back-and-forth copying laser distance measuring device 8 which measures a distance by a change in voltage to slide a Y-axis slide base by a Y-axis servomotor 6 and a Y-axis ball screw 7 by means of a microprogram in a sequencer until the value of voltage reaches a predetermined value. That is, a buffing is performed while keeping a distance between the buffing head and a surface to be buffed by automatically moving a buffing head in back-and-forth direction. When a buffing is performed, an X-axis is fixed and, when the buffing head is moved to the next buffing place, the X-slide base 12 is moved by an X-axis servomotor 4 and an X-axis ball screw 5.

摘要： PROBLEM TO BE SOLVED: To automatically copy and mill a deformed workpiece by copying a fillet weld part in a narrow part while keeping a distance between a surface to be cut and a milling tool constant by a distance measuring device. SOLUTION: If a fin 15 is deformed by welding, a distance between the fin 15 and a tool is measured by a right-left copying laser distance measuring device 9 which measures a distance by a change in voltage caused by oscillation in the direction of X axis around a fulcrum O of a bar for supporting a right- left copying roller 10. Next, an X-axis slide base 11 is moved by an X-axis servomotor 4 and an X-axis ball screw 5 by means of a microprogram in a sequencer until the value of voltage reaches a predetermined value. That is, a milling is performed while keeping a distance between a cutting head 1 and a surface to be cut by automatically moving the cutting head 1 in right-left direction.
