Abstract
PURPOSE:To eliminate adverse influence of strains easily despite the presence of the strains in the structural members for a juncture by using a thin walled metallic sleeve which can be deformed when pressed and sealing materials mounted on the outside circumference thereof, putting a light source in a metallic pipe and detecting the presence or absence of any clearance between the sealing materials and the metallic pipe. CONSTITUTION:A backing strip 8 is mounted to a thin walled metallic sleeve 7 which can be deformed by pressing, and rubber elastic sealing materials 9 are mounted on the outside circumference thereof. While such sleeve 7 is inserted into one metallic pipe 1 to be connected, a light source 14 is put in said pipe 1, and the clearance between the pipe 1 and the materials 9 is inspected by utilizing the light from said source. If there is any clearance, the sleeve 7 is deformed at that clearance part and the materials 9 try to close the clearance. After this is checked, a metallic pipe 1' to be connected is butted, and the strip 8 is located in the butted part 2s, then the parts 2 are welded.
