Abstract:
The welded material manufacturing method is provided with: a process for preparing a welding jig, which is disposed so as to straddle a line extended from the abutment line of the abutting parts of two plates and supports an end tab from a position that intersects with said extension line, and in which a groove, which is disposed along the extension line and through which a first shoulder can pass, and an open section, which faces said groove, are formed; a process for disposing the plates to abut against each other; a process for disposing the welding jig on an end of the abutment line; a process for setting an end tab on the welding jig and positioning said end tab with respect to the plates; a process for disposing the first shoulder and a probe connected to the first shoulder in a position that is on the groove side of the extension line; a process for disposing a second shoulder in a position corresponding to the first shoulder and the probe; a process for connecting the second shoulder to the probe so as to interpose the end tab between the first shoulder and the second shoulder; and a process for executing the friction stir welding.
Abstract:
A flange joint for structural members is provided, wherein by avoiding stress concentration at a welded portion, the cross-sectional size can be determined based on the base material strength, and a structure can be reduced in weight and size. In a flange joint (20) for structural members, structural members are connected to each other in a state where an end face (21a), for example, of an H-shaped steel beam (21) is connected to a structural-member-connecting face (22a) of an end plate (22) by welding and a non-connection face (22b) of the end plate (22) is coupled to another structural member. The structural-member-connecting face (22a) of the end plate (22), to which the end face (21a) of the H-shaped steel beam (21) is connected, is provided with recessed grooves (23) along the shape of the welded portion of the end face (21a).
Abstract:
A method and related apparatus for precision deploy-attaching beam-mount structure (38) to the outside of an elongate column (32) at plural, defined attachment sites that are distributed and spaced along the length of the column (32). The method involves (a) preparing an elongate column (32) to act as a travel way for a carriage (62) which is designed to transport and deploy beam-mount structure (38), shifting such a carriage (62) progressively along the column (32) from defined attachment site to defined attachment site and at each site, deploy-attaching from the carriage (62) to the column (32) the carriage-carried beam-mount structure (38).
Abstract:
A hat profile (11) has a tensile strength exceeding 1400 MPa and it has soft bands (20) with a tensile strength below 1100 MPa on its side flanges (15,16). The profile is welded to a cover (17) by single rows of weld dots (18). The side flanges have high strength zones (21,22) on both sides of the soft bands (20).
Abstract:
A shaped, sealed sandwich product is manufactured by press hardening of a sandwich blank consisting of two sheets (12, 13) with spacer material (14) and solder lying in between. The edges of the blank are excepted from the spacer material and the edges are pressed together in the press hardening so that the sheet edges are sealingly joined without spacer material. Alternatively, there is a sealing rim with spacer material along the edges.
Abstract:
Microfabricated particles are dispersed throughout a matrix to create a composite. The microfabricated particles are engineered to a specific structure and composition to enhance the physical attributes of a composite material. The microfabricated particles are generated by forming a profile extrudate. A profile extrudate is an article of indefinite length that has a cross sectional profile of a desired structure with micro-scale dimensions. Upon or after formation, the profile extrudate may be divided along its length into a plurality of microfabricated particles.
Abstract:
A beam working apparatus, includes opposed vice assemblies for holding and rotating a beam about a long axis thereof and a number of gantries that are arranged for translational motion along the beam. At least one tool head mount is provided fast with each of the gantries for a tool for working upon the beam. A number of motors are provided to selectively rotate the vice assemblies and move the gantries in order that the apparatus can be operated by a computerized control system.
