 Stray Current Corrosion Course Overview

Stray current corrosion poses a real risk to the rails, rail fasteners, tunnels, and other supporting structures. Among the many different types of corrosion, stray current corrosion is probably the most misused term by unqualified corrosion consultants worldwide who literally refer to any corrosion phenomenon beyond their comprehension as stray current corrosion. This mis-diagnosis often results in significant financial losses and serious safety lapses for facility owners and operators. This 3-day in-depth training course with hands-on sessions will give you the power to separate myth from fact on anything related to corrosion in general and stray current corrosion in particular. The course covers how to identify, detect, mitigate, monitor, and prevent stray current corrosion in DC rail transit systems. Attendees will have the opportunity to use stray current corrosion prediction and modeling software (SC-Compass) during the course.


This corrosion short course can be taken as online corrosion course, in-house training or on-site training corrosion course, and on-demand corrosion course. It can also be customized to meet the specific needs of your organization.

 In-House Training Corrosion Courses and On-Site Training Corrosion Courses


If you are concerned with corrosion in your company, in-house training or on-site training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all our corrosion courses can be customized to fit your organization's needs.


There is no limit to the number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises worldwide, and at a time convenient to your company.

 Corrosion Course-On-Demand


All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you (on an one-on-one basis) or for a small group from your company at a time and in a location convenient to you. This option costs significantly less than a full-scale in-house or on-site corrosion training program.

 Online Corrosion Courses and Distance Learning Corrosion Courses


All our corrosion short courses are available for online or offline distance learning. You can start an online corrosion course at any time and learn at your own comfortable pace and schedule, whenever and wherever you are. You have around-the-clock access to the interactive and media-rich course materials, virtual labs, course instructions and course assessments. Discussions and questions related to the corrosion courses are posted on the website or exchanged through email for a period up to 12 months. Video conferencing or instant messaging can also be arranged for discussions of course topics. For those who do not have ready access to internet, we can send you our online course materials on a CD-ROM, or DVD, or USB flash drive for offline distance learning.
