The invention provides a laser welding-brazing packaging method and device for a three-dimensional weld joint. The method comprises the steps of step S1, carrying out surface treatment on a joint of ato-be-connected device, and selecting low-temperature brazing filler metal with a proper size; step S2, performing in-situ melting on the low-temperature brazing filler metal through laser melting brazing, spraying the molten brazing filler metal to the joint through high-pressure airflow, and completing preliminary connection through an auxiliary wetting and filling method; and step S3, after the brazing filler metal is sprayed, applying a second laser to heat the brazing filler metal again for secondary remelting, conducting heat preservation aftertreatment on the weld joint after a periodof time, and completing metallurgical connection. According to the technical scheme, three heating procedures are adopted to sequentially complete melting, filling, wetting and interface reaction of the brazing filler metal, and rapid low-temperature welding is achieved; and compared with traditional one-time laser welding, the method has the advantages of being more sufficient in wetting and spreading, good in weld joint integrity, high in welding performance and surface quality and low in residual stress.

A touch display panel includes a first substrate, a second substrate, a plurality of active components, at least one conductive layer, a touch electrode, and at least one first conductive pattern. Theconductive layer is disposed on the first substrate, and the touch electrode is disposed on the second substrate. The first conductive pattern is disposed on the inner surface of the second substrateand electrically connected to the touch electrode. The first conductive pattern includes a first flat portion and a convex portion extending from the first flat portion toward the first substrate, wherein the convex portion is electrically connected to the corresponding conductive layer. A method of repairing the touch display panel has also been proposed.

The invention discloses an assembled floor which comprises an upper plate and a lower plate, wherein a support structure is arranged between the upper plate and the lower plate, the upper plate is composed of upper regular hexagonal ring cells, the lower plate is composed of lower regular hexagonal ring cells, and the lower plate is also provided with a support structure. The assembled floor is scientific and reasonable in structural design, and has a good balanced stressed structure. When people play various ball games on the assembled floor, the motion trajectory of a ball impacted with the floor does not deviate, and therefore, the assembled floor has good ball control capacity.

The invention provides a novel hole-pattern heavy-duty goods shelf stand column and a manufacturing method of the novel hole-pattern heavy-duty goods shelf stand column and belongs to the technical field of machinery. The novel hole-pattern heavy-duty goods shelf stand column solves the problem that an existing heavy-duty goods shelf stand column is poor in bearing capacity. The novel hole-pattern heavy-duty goods shelf stand column is provided with a stand column body, two oppositely-arranged first connecting parts, two second connecting parts and two clamping parts, wherein the edges of the two sides of the stand column body extend in the same direction to form the two first connecting parts; the sides, away from the stand column body, of the first connecting parts extend to form the two second connecting parts; the sides, away from the stand column body, of the second connecting parts extend in the same direction to form the two clamping parts; the stand column body is provided with at least one column of hook hole group arranged in the vertical direction; the distances between the adjacent hook hole groups gradually decrease from bottom to top; each hook hole group comprises a first hook hole and a second hook hole located over the first hook hole; each clamping part is provided with a column of plug pin holes arranged vertically, and the distances between the adjacent plug pin holes gradually decrease from bottom to top. The novel hole-pattern heavy-duty goods shelf stand column is simple in structure and high in bearing capacity; the manufacturing method is simple in procedure, and the production cost is saved.

The invention discloses a conformal construction method of a full-width type structure section of a warship, which mainly comprises the inverse construction of a left section and a right section. A left section and a right section are normally lif to a section bracket, and are combined on that section bracket to form a full-width structure section; Fix sectional inner wall panels, sectional outfitting and L-shaped stiffener panels; The steps of hoisting the section bracket with full-width structural segments to the final assembly area. The present invention is a section which can only be constructed in reverse state before, a scheme which can be constructed normally is provided, but also provides a full-width construction option for segments previously constructed only in half-width form,The method also changes the transportation form of the full-width structure segments which can only be transported in reverse state, so that the sections can be transported in a normal state, the structural deformation produced in the process of lifting, turning over, shelving, painting and the like of the sections is avoided, the construction scale of the sections is enlarged, and the pre-outfitting rate of the sectionss is improved.
