The 2-Day N.S. Sample Course is for students who may want a career in welding but are uncertain what is involved. The first day will be 4-hours of STICK welding and 4-hours of TIG welding. The second day will be 4-hours of MIG welding and a small fabrication project that is yours to keep. This way you get to try the four most used welding processes in the industry day in and day out.
