 In-House 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 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 3 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.

 PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors


If you are involved in teaching or training, you may wish to purchase a complete set of the trainer's package for this training course. The trainer's package comes complete with ready-to-use PowerPoint slides (fully editable) and test bank (with answer keys). These ready-to-use PowerPoint slides contain high quality color photographs, illustrations, animations, audio and video clips. The test bank contains questions in four categories: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning and open-ended discussions. The trainer's package is suitable for in-house training and university teaching. This is exactly the same package that WebCorr uses to deliver our current training course.

The one-time lump sum fee allows your organization to use the training package and also modify it. For example, your organization may modify the course contents and re-name/re-brand the course under your organization’s name. WebCorr only retains the copyright of the original PowerPoint slides and test bank.


Click here to contact us if you need more information on the trainer's package.
