Top 10 Questions for Oxyacetylene Burner Interview

1. What are the key safety precautions that must be taken when operating an oxyacetylene burner?

• Ensure that the work area is well-ventilated and free of flammable materials.
• Wear appropriate protective clothing, including gloves, eye protection, and fire-resistant clothing.
• Inspect the equipment regularly for leaks or damage and never operate a faulty burner.
• Store oxygen and acetylene cylinders securely and separately, in an upright position and secured with chains.
• Never smoke or work near open flames when handling oxyacetylene equipment.

2. What are the different types of flames produced by an oxyacetylene burner?

• Neutral flame: Blue inner cone with a slightly oxidizing outer cone, used for welding.
• Oxidizing flame: Shorter, bluer inner cone with a larger, more defined outer cone, used for cutting metal.
• Reducing (or carburizing) flame: Longer, brighter inner cone with a smaller outer cone, used for heating metal or brazing.

3. How do you adjust the flame of an oxyacetylene burner?

• Adjust the oxygen flow rate to control the inner cone length: shorter for neutral flame, longer for oxidizing flame.
• Adjust the acetylene flow rate to control the outer cone shape: smaller for oxidizing flame, larger for reducing flame.

4. What are the different welding techniques used with an oxyacetylene burner?

• Left-hand welding: Torch in left hand, filler rod in right, used for welding thin materials.
• Right-hand welding: Torch in right hand, filler rod in left, used for welding thicker materials.
• Forehand welding: Flame directed ahead of the weld pool, used for most general welding.
• Backhand welding: Flame directed behind the weld pool, used for welding thicker materials or when visibility is limited.

5. What are the different types of tips used on oxyacetylene burners?

Tips vary in size and shape depending on the desired flame size and shape, material being welded, and thickness of the metal.

6. What factors affect the quality of an oxyacetylene weld?

• Proper flame adjustment
• Correct welding technique
• Cleanliness of the metal surfaces
• Appropriate filler rod selection

7. How do you maintain an oxyacetylene burner?

• Clean the tip regularly to prevent clogging.
• Check and replace worn or damaged hoses and fittings.
• Lubricate moving parts as recommended by the manufacturer.

8. What is the difference between oxyacetylene welding and oxyacetylene cutting?

• Welding: Uses a neutral or reducing flame to join metal pieces by melting and fusing them together.
• Cutting: Uses an oxidizing flame to cut through metal by rapidly oxidizing and melting the metal.

9. Describe the process of cutting metal with an oxyacetylene burner.

• Set the burner to an oxidizing flame.
• Hold the torch at a 90-degree angle to the metal.
• Start the cut by preheating the metal along the desired cut line.
• Once the metal is hot enough, move the torch along the cut line, directing the flame slightly ahead of the cut.

10. What are the advantages and disadvantages of using an oxyacetylene burner?

Advantages

• Versatile tool for welding, cutting, and heating metal.
• Produces a hot, concentrated flame for precise work.
• Relatively low equipment cost.

Disadvantages

• Requires careful handling and safety precautions due to flammable gases.
• Produces fumes that require proper ventilation.
• Limited penetration depth compared to other welding methods.
