Special Special
Welding
and Cutting and
Processes
After studying this chapter, you will be able to:
• Identify several special welding processes used
in industry for unusual metals or unusual
positions.
• Identify several special cutting processes used in
industry.
• List the advantages of some special welding and
cutting processes that are used in industry.
Frequently Used Special
Processes
The welding, cutting, brazing, soldering, and sur-
facing processes discussed in earlier chapters of this
book are not the only processes available. The
American Welding Society lists over 100 different
welding and cutting processes. Refer to Chapter 2
(Figure 2-6) for a chart listing all these processes.
Among them are special processes used on unusual
metals, or in locations that are unusual. Extremely
thin or thick metals also require special welding and
cutting processes. Many of the special processes
discussed in the following sections are not found in
