WLD 264A - Introduction to CNC Plasma Arc Welding: Module A

2 Credits, 3 Contact Hours
1 lecture period 2 lab periods

Procedures and techniques in Computer Numerical Control (CNC) plasma arc cutting. Includes health, safety, and environmental practices; history of plasma arc cutting; software and coordinate systems; tool paths, importing images, and cutting with a CNC plasma machine.

Prerequisite(s): CAD 101  or CAD 117 ; WLD 110  and WLD 261 .
Information: Prerequisite(s) may be waived with welding industry experience. Constitutes approximately first one-half of WLD 264 . WLD 264A and WLD 264B  combined are equivalent to WLD 264 .
