Welding & Metal Fabrication (WMET), AAS

At Dunwoody College of Technology, the Welding & Metal Fabrication program provides students with the unique opportunity to combine skills from both welding and machining. Students gain the entry-level skills and theoretical knowledge to machine parts, layout assemblies for fabrication, weld assemblies, and finish weldments utilizing various welding processes and machine tools. 

Graduates from this program are prepared to enter the industry as welders, fabricators, machinists, and machine operators. 

The course of study includes: manual milling and turning; measurement and materials; job planning and layout; metallurgy; oxygen-fuel welding and cutting; shielded metal arc welding (SMAW-stick); gas metal arc welding (GMAW-MIG); gas tungsten arc welding (GTAW-TIG); and the various fabrication processes. 

The program's curriculum is closely aligned with standards set forth by National Institute of Metalworking Skills (NIMS) and the American Welding Society (AWS).

Arts & Sciences curriculum supports the technical coursework by enhancing the students' communication, mathematics, and critical thinking skills. 

A shorter certificate option that focuses only on welding is also available.
