 Corrosion Course Overview


corrosion short course: corrosion control and corrosion preventionEnvironmental Cracking is one of the key factors that can affect the structural integrity or limit the life of metallic structures. Environmental cracking is a general term that includes: stress corrosion cracking (SCC), caustic cracking, liquid metal cracking, corrosion fatigue, hydrogen blistering, hydrogen embrittlement (HE), hydrogen-induced cracking (HIC), stepwise cracking (SWC), stress-oriented hydrogen-induced cracking (SOHIC), sulfide stress cracking (SSC), soft-zone cracking (SZC), and hydrogen stress cracking (HSC).

This 5-day corrosion short course systematically and thoroughly covers the recognition, mechanisms, test methods and prevention of the various types of cracking phenomena. Also discussed in this corrosion short course is the NACE MR0175/ISO 15156 standard for the selection of crack-resistant materials for use in H2S-containing oil and gas environments.


This corrosion course is available for in-house training, online and distance learning worldwide. 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.


Click here to contact us for a quotation for in-house training corrosion courses.

 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.

 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 (30 lecture hours). 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 organizationís name. WebCorr only retains the copyright of the original PowerPoint slides and test bank.
