Hull lofting Linear lofting: manual lofting and machine (computer) lofting, manual lofting is generally 1:1 ratio, the sample table takes up a large area, requires more manpower and material resources, and is less used; Machine lofting is also called mathematical lofting. It relies on advanced technical software to lofting the hull. The mathematical lofting has high accuracy and does not occupy space and manpower. Machine lofting is widely used. Structure lofting and unfolding: lofting and unfolding of each structure, drawing the corresponding processing template and sample bar. Billing Sketch: Sketch the corresponding blanking. steel pretreatment Pretreatment of steel surface to eliminate stress. Steel correction: generally for mechanical methods, that is, the use of multi-roll straightening machine, hydraulic press, steel straightening machine, etc. Surface cleaning: a. Mechanical derusting method, such as shot blasting derusting method shot blasting derusting method, more widely used; B. Pickling rust removal method, also known as chemical rust removal, the use of chemical reactions; C. manual rust removal method, with hammer and other tools to knock rust component processing Edge processing: shearing, cutting, etc; Cold and hot processing: eliminate stress, deformation, etc; Molding processing: oil press, cold bending machine, etc. Hull Assembly Hull (parts) assembly, the various components of the combination of splicing into a variety of space we need shape. hull welding The shape of the assembled space is welded to become a permanent integral whole. tightness test All kinds of tightness test, such as coloring test, ultrasonic, X, etc. ship launching After the basic formation, all the volume below the design line is the immersion volume. Gravity launching: the general method is launching from the ship's platform, which is launched by the ship's own weight and sliding speed; Buoyancy launching: generally in the form of a dock; Machine launching: suitable for small and medium-sized ships, towed or hoisted by machinery and equipment. Ship Outfitting Ship outfitting to carry out a comprehensive outfitting system, mooring system, machine fitting, electrical equipment, pipe fitting and other aspects of the work. ship test Ship test berthing test, tilt test, trial (comprehensive test of the ship's performance).
Hull lofting
Linear lofting: manual lofting and machine (computer) lofting, manual lofting is generally 1:1 ratio, the sample table takes up a large area, requires more manpower and material resources, and is less used; Machine lofting is also called mathematical lofting. It relies on advanced technical software to lofting the hull. The mathematical lofting has high accuracy and does not occupy space and manpower. Machine lofting is widely used.
Structure lofting and unfolding: lofting and unfolding of each structure, drawing the corresponding processing template and sample bar.
Billing Sketch: Sketch the corresponding blanking.
steel pretreatment
Pretreatment of steel surface to eliminate stress.
Steel correction: generally for mechanical methods, that is, the use of multi-roll straightening machine, hydraulic press, steel straightening machine, etc.
Surface cleaning:
a. Mechanical derusting method, such as shot blasting derusting method shot blasting derusting method, more widely used;
B. Pickling rust removal method, also known as chemical rust removal, the use of chemical reactions;
C. manual rust removal method, with hammer and other tools to knock rust
component processing
Edge processing: shearing, cutting, etc;
Cold and hot processing: eliminate stress, deformation, etc;
Molding processing: oil press, cold bending machine, etc.
Hull Assembly
Hull (parts) assembly, the various components of the combination of splicing into a variety of space we need shape.
hull welding
The shape of the assembled space is welded to become a permanent integral whole.
tightness test
All kinds of tightness test, such as coloring test, ultrasonic, X, etc.
ship launching
After the basic formation, all the volume below the design line is the immersion volume.
Gravity launching: the general method is launching from the ship's platform, which is launched by the ship's own weight and sliding speed;
Buoyancy launching: generally in the form of a dock;
Machine launching: suitable for small and medium-sized ships, towed or hoisted by machinery and equipment.
Ship Outfitting
Ship outfitting to carry out a comprehensive outfitting system, mooring system, machine fitting, electrical equipment, pipe fitting and other aspects of the work.
ship test
Ship test berthing test, tilt test, trial (comprehensive test of the ship's performance).
