FAB1050 Basic Electric Welding

Introductory · 1 credit · TMT - Trades, Manufacturing and Transportation

Description
Students develop basic skills related to the safe use and operation of one or more common electric welding processes.
Prerequisite
FAB1010: Fabrication Tools & Materials
Parameters
Access to a materials work centre, complete with electric welding equipment and fabrication facilities, and to instruction from an individual with formal, specialized training in basic Gas Metal Arc Welding (GMAW) and/or Shielded Metal Arc Welding (SMAW).

Outcomes The student will:
