Title: Welding method of active metallic pipe and active metallic pipe plate
Inventor: YAO SHIN
IPC: B23K9/028
Filed: 1983-05-04
Abstract: PURPOSE:To prevent loosening of an expanded pipe owing to a deformation by welding heat and the consequent generation of a blow hole by keeping the pipe of an active metal pressed circumferentially from the inside surface of the pipe toward a pipe plate during welding of the pipe and the pipe plate so that no clearance is generated between the pipe and the pipe plate. CONSTITUTION:A pipe 2 of an active metal inserted into the pipe hole of a pipe plate 1 of an active metal having an easy tendency to generation of a blow hole in the weld zone is preliminarily expanded. A center rod fixing part 4a which is made smaller in diameter than the inside diameter of the pipe 2 is then inserted into the pipe 2 and a center rod actuating part 4b is pressed in an arrow direction so that the pipe 2 is kept circumferentially pressed from the inside surface. The part 4b and a torch 7 are attached to one body via a bearing 10 in this state and only the torch 7 is rotated while the part 4a and the part 4b are held stationary. A shielding gas 6 such as Ar is then blown to the weld zone. The pipe 2 is further kept circumferentially pressed to prevent the loosening of the expanded pipe owing to a deformation by welding heat.

Abstract: PURPOSE:To improve the measuring accuracy of the surface characteristic of a plate-shaped viscoelastic material by relatively moving a surface-flaw imparting indenter with respect to a sample stage, forming a flaw on the surface, and measuring the shape of the flaw after an arbitrary time. CONSTITUTION:Position adjusting handles 4 are provided at the front part and the side surface of a sample stage 2 and determine the position of the sample stage 2. The tip of a surface-flaw imparting indenter 9 is made of ceramics or metal. The indenter 5 is fixed to an indenter fixing fixed shaft 5-1. After the position of the indenter 5 is adjusted with the handles 4, a surface-flaw imparting load 6 is applied. The sample stage 2 is moved at a constant speed with a driving system. Thus, a flaw is formed on the surface of the sample. Then, a surface-shape measuring indenter 9 is moved in the direction perpendicular to the flaw 8 by using the driving system immediately after the formation of the flaw or after the elapse of arbitrary time. Then, the shape of the flaw is measured. At the same time, the depth of the flaw in which the indenter 5 is pressed into the sample is measured with a laser displacement gage which is attached to the upper part of the indenter 9. Thus, the measuring accuracy of the surface characteristic is improved.
