Individual contestant and team scored will be determined by tabulating examination and skill activity using 40% for written and 60% for welding skills.
A team score will be determined by adding the individual scores of each of the three welding divisions (Shielded Metal Arc, Oxygen Acetylene, and Gas Metal Arc Welding).
The Welding Contest is divided into three Sections and will rotate each year. Consult the CDE schedule to determine the current year's rotation.
The contest will be conducted at Southeast Community College Lincoln Campus. The skill activity portion of the contest will be conducted in the Welding Lab (K- 1) and the examination will be conducted in nearby classrooms.
