The OSE Metal Fabrication Certificate is the first in OSE's line of certification based on well-defined criteria and testing. The basic test involves MIG welding, torching, grinding, drilling, marking, and tool selection skills. These skills are based on a generalized skill set indispensible to effective functioning in OSE build events.
