Welding device for piecewise splicing of cruise ship sheets

The invention discloses a welding device for sectional splicing of cruise ship sheets, and relates to the technical field of sheet welding, the welding device comprises a supporting table, a positioning box is mounted above the supporting table, one end of the supporting table is connected with a workbench, a containing box is movably arranged in the positioning box, and a plurality of sheet bodies are placed in the containing box; an automatic welding machine body is installed on one side of the workbench. A first electric push rod is installed at one end of the supporting table, and a conveying mechanism is arranged at the other end of the supporting table. Under the cooperative action of the first electric push rod and the conveying mechanism, after two non-welded thin plate bodies are conveyed out, conveying is suspended, welding is conducted, and manual feeding of the thin plate bodies is replaced; by arranging the inclined plate and the conveying belt body, the two welded thin plate bodies are pushed by
