Top 10 Questions for Welder-Fitter Apprentice Interview

1. What is the difference between welding and brazing?

Welding and brazing are both techniques used to join metals, but there are some key differences between the two processes.

• Welding is a permanent joint, while brazing is a semi-permanent joint.
• Welding uses heat to melt the metals together, while brazing uses heat to melt a filler metal that flows into the joint.
• Welding is typically used for stronger joints, while brazing is used for more delicate joints.

2. What are the different types of welding processes?

Arc welding

• MIG (metal inert gas) welding
• TIG (tungsten inert gas) welding
• Stick welding

Gas welding

• Oxy-acetylene welding
• Propane welding

3. What are the different types of welding joints?

• Butt joint
• Edge joint
• T-joint
• Corner joint

4. What are the safety precautions that must be taken when welding?

• Wear appropriate protective clothing, including a welding helmet, gloves, and apron.
• Ensure that the work area is well-ventilated.
• Keep the welding torch away from flammable materials.
• Be aware of the potential for electrical shock.

5. What is the purpose of a welding rod?

• Filler metal that is added to the weld joint to create a strong bond.
• Helps to protect the weld from corrosion.
• Can be used to create different types of weld joints.

6. What is the difference between a tack weld and a fillet weld?

• Tack weld is a small weld used to hold two pieces of metal together temporarily.
• Fillet weld is a larger weld used to create a strong, permanent joint.

7. What are the different types of welding defects?

• Cracks
• Porosity
• Undercut
• Cold lap

8. What is the best way to prevent welding defects?

• Use the right welding technique for the job.
• Use the right welding equipment.
• Inspect the weld joint regularly.
• Repair any defects immediately.

9. What are the different types of welding symbols?

• Basic weld symbols
• Joint preparation symbols
• Dimension and other symbols

10. What is the AWS (American Welding Society)?

• A non-profit organization dedicated to advancing the science, technology, and application of welding.
• Develops welding standards and certifies welders.
• Provides training and education programs for welders.
