Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about your TIG welding experience. What materials and thicknesses have you welded most?

What they are checking: Whether their TIG and GTAW experience is real and matches the work they would do here.

This first shift starts at 4 in the morning, Monday to Thursday. How does that fit your routine?

What they are checking: Whether they can reliably show up for a very early ten-hour shift.

How do you keep up with the production schedule without letting weld quality slip?

What they are checking: Whether they can balance speed and quality instead of rushing welds to hit a number.

What would you do

You find a stack of parts with defective material before you start welding. What do you do?

What they are checking: Whether they report faulty material or equipment to the supervisor rather than welding over a problem.

About the work

How do you control heat to keep a part from warping or distorting?

What they are checking: Whether they understand heat input, sequencing and tacking, which the posting calls out directly.

The posting mentions settings up to 250 amps, 32 volts and 400 IPM wire speed with .045 to .052 metal core wire and 90/10 gas. What are you looking for when you dial in a machine like that?

What they are checking: Whether they can set up wire-fed equipment from the stated parameters and read the puddle to adjust.

Walk me through how you read a blueprint and weld symbol before you start fitting parts.

What they are checking: Whether they can interpret weld symbols and dimensions to build parts correctly the first time.

Which positions are you comfortable welding in, and how does your technique change for overhead work?

What they are checking: Whether they can weld vertical, flat and overhead as the posting requires, with real technique changes.

You notice porosity in a weld you just finished. What are the likely causes and what do you do?

What they are checking: Whether they can diagnose common weld defects like gas coverage or contamination and fix them properly.

How do you prep surfaces before welding, and why does it matter so much for TIG?

What they are checking: Whether they understand that TIG is very sensitive to cleanliness and take prep seriously.
