Demonstration should include
- following all general safety procedures for the lab/shop
- following all recommended safety guidelines for cold and hot metalworking procedures, such as welding (e.g., arc, 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 a 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 shielded metal arc welding (SMAW) or stick welding, instead of a gas metal arc welding (GMAW) when repairing farm machinery?
