A number of welding processes are commonly used to assemble metallic components. The most familiar type is arc welding. This type of welding produces a weld pool through the intense heat emitted by an electric arc.
This course covers the safety factors related to arc welding (handling, setting-up, adjustments, control), the operating principles of the various electric arc welding processes, and how to select the proper electrodes depending on the metals and the welding conditions.
Topics covered in this course include:
- electricity basics,
- arc welding machines,
- arc welding processes,
- electrodes (consumables),
- setting-up an arc welding unit,
- weld beads,
- troubleshooting an arc welding unit,
- preventive maintenance, and
- suggestions for practical exercises.
