- Cathodic protection is a more advanced method of corrosion protection. Cathodic protection involves using an electrical current to protect the steel from corrosion. This is done by connecting the steel to a sacrificial anode, which is made of a less noble metal than steel. The anode will corrode instead of the steel, protecting the steel from corrosion.
The choice of corrosion protection method depends on a number of factors, including the size and complexity of the steel structure, the type of marine environment in which it will be used, and the desired lifespan of the structure. By understanding the different corrosion protection methods available, you can make informed decisions about the best corrosion protection method for your marine steel fabrication project.

In marine steel fabrication, quality control is of paramount importance. Marine steel structures are used in harsh and demanding environments, and they must be able to withstand the elements and perform as intended. Quality control ensures that the fabricated structure meets the required standards and specifications, and that it is safe and fit for its intended purpose.
- Materials testing: The first step in quality control is to ensure that the materials used in the fabrication process meet the required standards. This involves testing the materials for their strength, durability, and corrosion resistance.
- Fabrication process control: The fabrication process itself must also be controlled to ensure that it meets the required standards. This involves monitoring the welding, cutting, and forming processes to ensure that they are carried out correctly and that the fabricated structure meets the required specifications.
- Inspection and testing: Once the fabricated structure is complete, it must be inspected and tested to ensure that it meets the required standards. This involves visual inspection, as well as non-destructive testing methods such as ultrasonic testing and radiographic testing.
- Documentation and traceability: Quality control also involves maintaining proper documentation and traceability throughout the fabrication process. This ensures that all materials and processes can be traced back to the final product, and that any problems can be quickly identified and corrected.
By implementing a comprehensive quality control program, marine steel fabricators can ensure that their products meet the required standards and specifications, and that they are safe and fit for their intended purpose.
