AWS Welder Material & Equipment Handling 1 — Questions and Answers
Question 1: What is the proper way to store welding electrodes to prevent moisture absorption?
- In an open-air container
- In a heated storage container (Correct answer)
- In a plastic bag
- On a metal workbench
Correct answer: In a heated storage container
Welding electrodes should be stored in a dry, temperature-controlled environment, and low-hydrogen electrodes should be kept in heated storage to prevent moisture absorption.
Question 2: Which factor should be considered when selecting a welding filler metal?
- Cost of the filler metal
- Base metal composition (Correct answer)
- Brand of the electrode
- Welding speed
Correct answer: Base metal composition
The filler metal must match the base metal's mechanical properties and composition to ensure a strong and durable weld.
Question 3: What is the primary purpose of a welding positioner?
- Increase the size of the weld
- Reduce the need for personal protective equipment
- Hold and rotate the workpiece for better access (Correct answer)
- Increase shielding gas efficiency
Correct answer: Hold and rotate the workpiece for better access
A welding positioner holds and rotates the workpiece, allowing welders to achieve consistent weld quality and better access to difficult angles.
Question 4: Which safety precaution is necessary when handling compressed gas cylinders for welding?
- Store cylinders in a horizontal position
- Secure cylinders in an upright position (Correct answer)
- Keep cylinders next to heat sources
- Lay cylinders on the ground when in use
Correct answer: Secure cylinders in an upright position
Compressed gas cylinders must always be stored upright and secured to prevent them from falling, which could cause dangerous leaks or explosions.
Question 5: Which type of metal is most commonly used for structural welding?
- Stainless steel
- Aluminum
- Carbon steel (Correct answer)
- Titanium
Correct answer: Carbon steel
Carbon steel is widely used in structural welding due to its strength, affordability, and ease of welding with various processes.
Question 6: How should a welder properly lift heavy welding equipment to prevent injury?
- Bend at the knees and lift with the legs (Correct answer)
- Use only the back muscles for lifting
- Carry heavy equipment above shoulder level
- Drag equipment across the floor instead of lifting
Correct answer: Bend at the knees and lift with the legs
Using proper lifting techniques, such as bending at the knees and keeping the back straight, helps prevent injuries when handling heavy welding equipment.
