Title: (Optional) Demonstrate metalworking skills.
Course: Agricultural Production Technology (18301-I) > Section: Using Mechanics in Agricultural Production

Demonstration should include

- following all general safety procedures for the lab/shop
- taking all related safety tests
- following all recommended safety guidelines for cold and hot metalworking procedures, such as welding (e.g., Gas Metal Arc Welding [GMAW/MIG], Gas Tungsten Arc Welding[GTAW/TIG], Shielded Metal Arc Welding [SMAW], and Flux Cored Arc Welding [FCAW], oxy-fuel gas) and cutting
- identifying hazards encountered in welding
  - fire hazards (e.g., combustibles)
  - specific burn and eye hazards
    - heat
    - sparks
    - high voltage
    - hot metal
    - flammable material
    - arc flash
  - electrical hazards
  - machinery and tool hazards
  - fumes and airborne contaminants
  - confined space
  - compressed gases
  - hazardous waste
- identifying various types of metalworking (i.e., cold, hot) used in production agriculture
- using welding equipment in production agriculture to perform a
  - butt joint
  - lap joint
  - corner joint
  - T- joint
  - edge joint
- utilizing weld beads (e.g., stringer bead, weave bead) and passes to create the joint
- constructing a metalworking project, including bill of materials.

Process/Skill Questions:

- How are metalworking skills used in agriculture?
- Why does one need plans and a bill of materials before starting a metalworking project?
- What should be done to the weld joint prior to welding?
- How does one decide which metalworking process to use to make repairs in production agriculture?
- Why would one choose to use SMAW or stick welding, instead of a GMAW when repairing farm machinery?
