Hull Structural Steel And Process

Introduction to the

Since 1961 since the foundation, undertake and participate in the all ship structural steel in our country and related materials and technology research and development tasks, in view of the various types of ship structure design, construction, service and maintenance of the technical requirements of materials and technology to carry out a large number of materials development and application research, technology development and application of the research, performance evaluation technology research, hull structure failure analysis and repair, etc. After 50 years of development, the establishment of a complete hull structural steel and all kinds of form a complete set of materials and technology research and development conditions, to form the perfect structure material and technology of the engineering application adaptability evaluation technology system, created a rich practical experience and theoretical basis of solid scientific research personnel, has solved the hull structure material and process a large number of technical problems in engineering application, satisfied the all ship model in different stages of the development of our country demands for material and process technology, ensure the service safety and reliability of naval ships all shapes and sizes, and support the development of various new ships.

The main research direction

Basic properties characterization of materials

Through stress-strain properties, phase transition behavior and thermal parameters, corrosion, fracture parameters, fatigue parameters determination of the basic material parameters such as the basic characteristic of the system research of hull structural steel and welding joint.

Safety and reliability evaluation for engineering applications

Through dynamic tear drop, drop weight tear,, explosion bulge, wide plate tensile fatigue test, structure unit, real sea hanging pieces and engineering model test system research of hull structural steel and welded joint fracture resistance, fatigue resistance and corrosion resistance.

Welding engineering applicability evaluation

By shipyard under the condition of actual construction condition and the simulation of various welding crack sensitivity test of welding process, a variety of operating conditions can be sexually experimental study on the engineering application of form a complete set of hull structural steel welding process adaptability.

Hot and cold processing technology development and engineering applicability evaluation

For a wide variety of hull steel development corresponding heat treatment process, water and fire bending plate process, initiation of orthopaedic technology and hot and cold forming process.

Failure analysis and repair process

For a wide variety of hull structure, analysis of the causes of the mechanism and failure behavior and make feasible repair process.
