Principles of Welding

This course provides an introduction to the principles of welding technology. The course describes the process of welding and how it affects welded materials and structures. It describes the electric circuits that are used to generate welding arcs, material properties, and the metallurgical and dimensional effects of welding on structures. The course also provides an overview of weld design concepts including efficient weld sizing and communication of weld and welding information through weld symbols on drawings.

This is an online, instructor-supported course, allowing you to work at your own pace and convenience.

You Will Learn To

•  Explain how to use and application of common welding processes
• Describe basic weld design concepts, such as weld size determination and communication through weld and welding symbols on drawings
• Explain how welding affects various welded materials, including metallurgical and dimensional changes
• Describe the advantages and disadvantages of various arc-welding processes
• Identify basic electric circuits that are used to accomplish arc welding
• Identify weld inspection techniques, including non-destructive examination
• Identify common problems with welding processes and explain how to troubleshoot them

Who Should Attend
New technologists, engineers, managers and quality personnel who wish to understand the fundamental principles of welding to control and troubleshoot welding processes, reduce operating cost and improve the quality of their product. It is an ideal prerequisite to the ASME B&PVC Section IX Course for those individuals with little or no prior welding experience.

To take this course you should have a personal computer, Web browser, Internet connection, and software to display PDF files (such as Adobe Reader^®).
