Welding Technology

Exit Point I: Structural Welder. Upon completion of WELD 1410, 1420, 1430, and 1440, students will be eligible for a certificate.

Exit Point II: Combination Welder. Upon completion of requirements in Exit Point I and WELD 1450, 1460, 1470, and 1480, students will be eligible for a certificate.

Capstone Experience: Graduation with a Combination Welder Certificate or an Associate of Applied Science Degree in Welding requires successful completion of a comprehensive exit exam.
