摘要:
The present invention relates to a processing apparatus and a processing method with which a cutting target may be processed with ease and a superconducting accelerating cavity may be formed with high precision. The processing apparatus, which processes a hollow workpiece (10A) with a large diameter portion (11) at one side and a small diameter portion (12) at the other side to form a half cell (10), comprises a fixture (1) which fixes the workpiece (10A), a rotary drive portion which turns the fixture (1), and a cutting tool (4) which cuts the workpiece (10A). The fixture (1) is formed of a plurality of members, and, when a first cutting-target part of the workpiece (10A) is cut, the members are assembled in a first pattern so that the first cutting-target part is exposed. When a second cutting-target part of the workpiece (10A) is cut, the members are assembled in a second pattern so that the second cutting-target part is exposed. The assembly of the members is changed from the first pattern to the second pattern without having to remove the workpiece (10A).

A welding system of cylindrical structures which welds a welding end surface of an upper cylindrical structure and a welding end surface of a lower cylindrical structure, each of which being an end surface in an axial direction thereof and facing each other, includes: two or more welding apparatuses which are opposite to the welding end surfaces of the upper cylindrical structure and the lower cylindrical structure and are disposed at equal arrangement intervals in the circumferential direction of the cylindrical structures; a moving device which is configured to rotate the upper cylindrical structure and the lower cylindrical structure relative to the welding apparatuses in a circumferential direction of the cylindrical structures; and a control device which is configured to control operations of the welding apparatuses and the moving device, wherein each of the welding apparatuses has a filler metal and a heating source which melts the filler metal, and is configured to melt and fuse the filler metal on the welding end surfaces to thereby weld the welding end surfaces, and the control device is further configured to continuously rotate the upper cylindrical structure and the lower cylindrical structure by an angle of the arrangement interval of the welding apparatuses by the moving device, while welding the welding end surfaces with the welding apparatuses.
摘要:
To prevent poor quality of weld in a welding process for a thick material or for welding a gap, the laser welding apparatus has granular flux (3) supplied to a side of the base material (W) opposite to the side where a laser beam is directed and a pressing member (5) that presses the granular flux onto the base material (W) upon receiving fluid therein. Either the flux prevents the laser beam that coming through the base material (W) from penetrating the flux or the thickness of molten flux is selected so that the laser beam coming through the base material (W) does not penetrate the molten flux.
