WLD 264 - Introduction to CNC Plasma Arc and Basic Robotic Welding 4 Credits, 6 Contact Hours 2 lecture periods 4 lab periods
Procedures and techniques in Computer Numerical Control (CNC) plasma arc cutting and robotic automated welding. 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. Also includes programming and operation procedures for Gas Metal Arc Welding (GMAW) process using a Fanuc R30iA robotics welding cell, Teach Pendent Programs (TPP), and maintenance.
Prerequisite(s): CAD 101 or CAD 117 ; WLD 110 and WLD 261 . Information: Prerequisite(s) may be waived with welding industry experience. WLD 264A and WLD 264B combined are equivalent to WLD 264.
