Arc Welding Basics

What are the different types of welding rods used in arc welding?

• Mild Steel Rods, Stainless Steel Rods, Cast Iron Rods, Aluminum Rods

• Brass Rods

• Titanium Rods

• Copper Rods

List three important safety precautions to follow during arc welding.

• Wear loose clothing and jewelry while welding

• 1. Always wear appropriate personal protective equipment such as gloves, helmet, and clothing to protect against burns and sparks. 2. Ensure proper ventilation in the work area to prevent inhalation of harmful fumes and gases. 3. Inspect welding equipment regularly for any defects or malfunctions to prevent accidents.

• Use welding equipment with visible defects

• Weld in a confined space without proper ventilation

Explain the basic welding techniques that beginners should learn for arc welding.

• Use a high travel speed

• Keep the arc length too short

• Place the bead randomly

• Strike an arc, Maintain a consistent travel speed, Control the arc length, Practice proper bead placement

How do you choose the right welding rod for a specific welding project?

• Consider factors such as base metal type, thickness, welding process, and desired weld strength. Match rod material to base metal, select appropriate diameter, choose rod type based on welding technique, and consult welding charts.

• Select the rod randomly without considering base metal type

• Pick the thinnest rod available for all projects

• Choose the rod color based on personal preference

Why is it important to wear protective gear while arc welding?

• To enhance hearing abilities

• To improve eyesight

• To prevent injuries from sparks, UV radiation, and hot metal particles.

• To keep warm in cold weather
