Answers Graded A| 2025/2026 Review
Shielded metal arc welding is also called stick welding
Suitable arc welding for farm use are fairly easy to use, relatively inexpensive, reliable
The output of a welder is relatively low voltage and a high amperage
Types of polarity on dc welders includes straight and reversed
What is the primary use of arc welding in agriculture?
Arc welding is primarily used for repairing and fabricating agricultural equipment such as
plows, harrows, and cultivators.
How does arc welding help in farming operations?
Arc welding allows for the repair of broken metal parts, improving the longevity and
functionality of farming machinery.
What types of metals are commonly welded in agricultural arc welding?
Steel, stainless steel, and mild steel are commonly welded in agricultural arc welding.

, What are the advantages of arc welding in agricultural applications?
Arc welding provides strong, durable joints and is effective for repairing heavy-duty
equipment in agricultural settings.
What is the recommended electrode for welding farm equipment made of mild steel?
E6011 or E7018 electrodes are commonly used for welding mild steel farm equipment.
How does the choice of welding current affect the quality of the weld in agriculture arc welding?
Higher welding currents produce stronger welds, but too high a current can lead to burn-
through, while lower currents may result in weak joints.
What is the purpose of shielding gas in arc welding?
Shielding gas protects the weld pool from contamination by the atmosphere, ensuring a clean
and strong weld.
What safety precautions should be taken when performing arc welding in agricultural settings?
Proper protective gear, such as welding helmets, gloves, and aprons, should be worn, and the
work area should be clear of flammable materials.
What is a common issue encountered when welding thick metal parts on agricultural equipment?
Heat distortion and warping are common issues when welding thick metals, which can be
minimized with controlled welding techniques.
