Technicians, engineers, and students in general who are interested in gaining insight into how corrosion works in metals and the means the industry offers to protect them, especially cathodic protection systems.

This course is aimed in particular at technicians engaged in project engineering, assembly and commissioning of facilities, and personnel who perform maintenance and operation of industrial processes with metal structures exposed to the corrosion, whether buried, submerged or in concrete structures in the atmosphere.

Necessary Prerequisites: No prerequisites required. Yes with a basic level of general training.

Recommended Prerequisites: It takes a lot of desire and time to study the course.

The student will learn to:

• Know the phenomena that cause corrosion.
• Know the protection systems and use the most appropriate ones in each case.
• Know, calculate and design a system of passive and active cathodic protection.
• Specify cathodic protection equipment.
• Protect structures from external influences (power lines, railways and other cathodic protections).
• Install, commission and maintain a cathodic protection system
