AISC Fabricator common mistakes
AISC Fabricator · Understand the traps and how to avoid them.
Describing the fabricator's organizational chart only as a list of names and titles, without stating who holds authority for quality decisions or how the quality function reports relative to production.
Candidates memorize titles from their own shop and assume the examiner shares that context, so they omit the reporting lines and authority relationships the question is actually testing.
What to do instead
For each role, state the reporting line, the scope of authority (especially stop-work or hold authority for nonconforming product), and how the quality function is independent of production pressure.
Presenting experience as a total years-in-business figure with no breakdown of the specific work types, sizes, codes, or project delivery methods performed.
Years of service feels like the strongest credential, so candidates lead with it and never map experience to the scope the question describes.
What to do instead
Break experience into categories: project types, tonnage ranges, code editions worked to, welding and coating processes, and roles held. Tie each category to the requirement being asked about.
Claiming a written procedure exists without naming its title, revision control, approval authority, and where it is invoked in the workflow.
Candidates know their shop has procedures but have never read the document control system, so they answer at the level of 'we have a procedure for that.'
What to do instead
Cite the procedure by name and revision, state who approves it, how revisions are distributed and superseded copies withdrawn, and which hold point or inspection step triggers its use.
Answering a technical question with a general practice statement instead of the specific code clause, acceptance criterion, or tolerance value being tested.
Candidates rely on shop-floor habit rather than the referenced standard, and habit often reflects a looser or older practice than the current edition requires.
What to do instead
Anchor each answer to the governing document and edition, quote the acceptance criterion or tolerance, and state what happens when the criterion is not met.
Listing equipment by brand or model name without stating capacity, calibration status, maintenance interval, or the operating limits that determine whether it is suitable for the work.
Candidates describe the machines they use daily and assume the examiner will infer capability, so suitability and calibration are left unstated.
What to do instead
For each machine, give rated capacity and envelope, calibration or verification frequency and records, preventive maintenance schedule, and the condition that removes it from service.
Treating commitment to quality as a slogan or a statement of pride rather than describing measurable indicators, review cadence, and corrective action follow-through.
Quality culture is easy to talk about abstractly, and candidates default to attitude language because they have not tracked the metrics behind it.
What to do instead
Name the metrics (rework rate, NCR count and closure time, first-pass yield, audit findings), who reviews them and how often, and give one example of a corrective action carried through to verification of effectiveness.
Describing a quality manual or procedure as complete without showing how personnel are trained on it and how competence is verified.
Candidates equate a documented procedure with an implemented one and skip the training and qualification evidence that closes the loop.
What to do instead
Describe the training path for each relevant role, the record that proves qualification, the requalification interval, and how a revision to the procedure triggers retraining.
Giving an organizational answer that never distinguishes between the person who performs an inspection and the person who accepts the product.
In small shops the same person often does both, so candidates describe reality without recognizing the independence the question is probing.
What to do instead
State explicitly who performs, who verifies, and who has final acceptance authority, and explain how independence is preserved when staffing is limited.
Describing equipment maintenance only as 'per manufacturer recommendations' with no schedule, owner, or record.
It is a safe-sounding phrase that avoids committing to specifics the candidate may not know.
What to do instead
Provide the interval, the responsible role, the record kept, and the criteria for calibration failure or out-of-tolerance handling.
Answering a scenario about nonconforming product by describing rework only, omitting segregation, disposition authority, and customer or engineer notification where required.
Rework is the familiar daily response, so candidates stop there and never address containment or disposition routing.
What to do instead
Walk the full sequence: identify and segregate, document the nonconformance, route disposition to the authorized party, obtain any required outside approval, then rework and re-inspect with records retained.
