Voltage

Term from Welding industry explained for recruiters

Voltage is a basic measure of electrical power used in welding. Think of it like water pressure in a pipe - it determines how strong the electrical current is that creates the weld. When you see "voltage" mentioned in welding resumes or job descriptions, it usually refers to a welder's ability to properly set and control the power settings on welding machines. Different materials and types of welds need different voltage settings, so understanding voltage is a key skill for welders. You might see it referred to as "volts" or "V" in job descriptions.

Examples in Resumes

Example Interview Questions

Senior Level Questions

Q: How do you determine the correct voltage settings for different materials and thicknesses?

Expected Answer: A senior welder should explain how they consider material type, thickness, welding position, and desired penetration to select voltage settings. They should mention experience with multiple types of materials and the importance of testing settings before starting the main work.

Q: How would you train a junior welder about voltage control?

Expected Answer: Should demonstrate teaching ability by explaining how they would break down voltage concepts into simple terms, show practical examples, and emphasize safety considerations while adjusting power settings.

Mid Level Questions

Q: What problems can incorrect voltage cause in welding?

Expected Answer: Should be able to explain common issues like poor penetration with low voltage or burn-through with high voltage, and how to identify and correct these problems.

Q: How do you adjust voltage when switching between different welding positions?

Expected Answer: Should explain how different positions (flat, vertical, overhead) require different voltage settings and why, demonstrating practical knowledge of voltage adjustment.

Junior Level Questions

Q: What is voltage in welding and why is it important?

Expected Answer: Should be able to explain that voltage controls the power of the welding arc in simple terms and understand that different jobs need different voltage settings.

Q: How do you safely adjust voltage on a welding machine?

Expected Answer: Should demonstrate basic knowledge of machine controls, safety procedures when adjusting settings, and understanding of when adjustments are needed.
