Abstract: The present disclosure provides a forced forming apparatus for a plurality of welds in a narrow space, belonging to the field of welding technology, and the apparatus includes a plurality of first backing members arranged adjacent to one another, and second backing member group structures configured to interconnect every two adjacent first backing members; each of the second backing member group structures is used for adjusting a distance between two adjacent first backing members; and a frame enclosed by the first backing members and the second backing member group structures is configured to be clamped on back sides of welds of a workpiece to be welded; and the first backing members and the second backing member group structures are both provided with forming arced faces, and the forming arced faces are arranged opposite to the welds of the workpiece to be welded.

Abstract: The present invention provides a welding apparatus and a welding method for ultra-narrow welding gap, relating to the technical field of welding with an ultra-narrow welding gap. The welding apparatus for ultra-narrow welding gap comprises: a blowing mechanism, a conductive nozzle and an industrial water-cooling unit. The industrial water-cooling unit is connected to the blowing mechanism. A medium flow of the industrial water-cooling unit flows through the inside of the blowing mechanism. The industrial water-cooling unit is configured to reduce a temperature of the shielding gas outputted by the blowing mechanism and a temperature of the conductive nozzle.

Abstract: A modular multipurpose offshore operation platform comprises a floating structure having a lower portion submerged below the surface of the sea, and a platform structure provided at an upper surface of the floating structure. An integrated work platform comprises at least two modular multipurpose offshore operation platforms. Framework structures of two adjacent operation platforms are detachably and fixedly connected, and floor boards of the operation platforms collectively form a deck. A transportation method transports goods to the platform by means of a hoist, and a hoist bracket with a rotating roller. The platform can achieve standardized production, and is flexible and has multiple functions.

Abstract: A maritime green human settlement system and a modularized construction method therefor. The maritime green human settlement system comprises at least one floor unit (1), solar photovoltaic plates (2), and a deck (3). The floor unit (1) is mounted on the deck (3). The solar photovoltaic plates (2) are mounted on the top surface of the highest floor unit (1). Each floor unit (1) comprises at least one room and indoor furniture. The room and the indoor furniture are formed by means of dislocated splicing of at least three modules (4), and at least one recessed portion (H) is formed at splicing positions. The maritime green human settlement system can form multiple indoor-outdoor spatial relationships; the flexibility is high, the construction period is short, and costs are low.
