Three common ways to create the heat that is applied to the parts being joined are electric arc welding, resistance welding, and gas welding. In arc and gas welding, filler materials are melted and added to the weld puddle to give the joint greater strength. It is the job of the welder to control the amount of heat and the size of the melted area and to add the proper amount of filler material in order to form a strong joint.

Employment for welders is expected to increase due to a greater demand. This demand, high skill requirements, and working conditions that are often difficult combine to make the earnings in this field above average to excellent.

Students who successfully complete sections A through H on the Welding / Fabrication Target List, and are recommended by their Instructor, will have completed Level 1 of the American Welding Society (AWS ) welding certification program, and are eligible for advanced placement in the NCCVT Welding Apprenticeship Program.
