Basics of Welding

Welding is the joining of two or more pieces of metal by applying heat and/or pressure to produce a localized union through fusion (melting) or diffusion across the interface that forms the joint. Many of the common welding methods employ only heat to melt the metals at the interfaces (fusion welding) without application of pressure. Arc welding and oxyfuel welding are examples of processes that use heat to melt the interface and then allow a joint to form by solidification of the molten metal. At the opposite extreme, metals can be welded together by pressure alone. This self-guided digital course uses helpful visuals, narrated animations, and interactive quizzes to teach the basic principles of welding and welding technique.

• Conclusion

Target Audience

This is an ideal first short course for anyone who needs a working understanding of the basic principles of welding and welding techniques. It has been designed for those with no previous training in welding, such as technical, laboratory, and sales personnel; engineers from other disciplines; management and administrative staff; and non-technical support staff such as purchasing and receiving agents.

 Learning Objectives:

• Define the term: welding
• Describe the basic principles of:
  • Arc welding
  • Electroslag welding
  • Oxyfuel gas welding
  • Resistance welding processes
