Weilding participants will meet  in rooms V103 and V104 for registration. The rooms are located by the SCC Registration near the east entrance. 

The welding event will consist of the following divisions:

  1. Shielded Metal Arc Welding
  2. Oxygen Acetylene Welding
  3. Gas Metal Arc Welding

Each division will involve a 30 minute written test and a 30 minute skill test. A 10 minute orientation for each division will also be included, for a total of 70 minutes per event division. Safety will be a big part of the event and will be emphasized at all times.
