Key Responsibilities and Required Skills for Iron Inspector

🎯 Role Definition

The Iron Inspector is responsible for ensuring that iron castings, forgings, machined components, and welded assemblies meet print specifications, customer requirements, industry standards and internal quality systems. This hands-on role combines visual, dimensional and non-destructive testing (NDT) inspection techniques, documentation and root-cause investigation to prevent nonconforming product from reaching customers. Ideal candidates are experienced in GD&T, CMM or manual gauging, magnetic particle and liquid penetrant testing, and have a disciplined approach to documentation, calibration, and continuous improvement.

Core Responsibilities

Primary Functions

Perform visual inspections of iron castings, forgings and welded assemblies to detect surface defects (porosity, cracks, cold shuts, fins, misruns), ensuring parts meet customer print and specification requirements prior to release.
Conduct dimensional inspections using calipers, micrometers, height gauges, bore gauges, gauges, and optical comparators to verify tolerances and features per GD&T callouts on engineering drawings.
Program, operate and validate coordinate measuring machines (CMM) for first article inspections, production sampling, and complex dimensional verification; analyze and document CMM reports for conformity and trend analysis.
Execute non-destructive testing (NDT) including magnetic particle inspection (MPI), liquid penetrant inspection (LPI/PT), ultrasonic testing (UT), and visual weld inspection, following written procedures and NDT acceptance criteria.
Read and interpret engineering drawings, bills of materials (BOM), blueprints and geometric dimensioning and tolerancing (GD&T) symbols to drive inspection decisions and acceptance/rejection criteria.
Perform First Article Inspections (FAI) and prepare FAI reports (AS9102 or customer-specific formats) to obtain part approval and support new product introductions.
Document inspection results accurately in quality records, inspection reports, control plans, and manufacturing execution systems (MES); ensure traceability of parts, gages and inspection data.
Identify, segregate and disposition nonconforming materials; write clear nonconformance reports (NCRs), perform containment actions, and coordinate rework or scrap with production and engineering.
Maintain and verify inspection gages and test equipment; perform routine verification checks and initiate calibration actions in accordance with ISO 9001/AS9100 and internal calibration schedules.
Perform sample-based statistical process control (SPC) checks on production runs, record measurement data, create control charts and escalate out-of-control conditions to Quality or Production leads.
Support root cause investigations for quality incidents by collecting objective evidence, participating in 8D/CAPA or RCA processes and implementing corrective/preventive actions to reduce recurrence.
Communicate inspection findings and dimensional issues to production, engineering, and suppliers; collaborate to determine disposition and required process adjustments.
Validate surface finish, heat-treatment, coating, plating and metallurgical requirements by checking specifications, performing simple hardness checks, and ensuring compliance with specified standards.
Conduct in-process inspections at defined operation stages to prevent downstream defects and ensure process capability is maintained through the production flow.
Prepare and maintain quality documentation for customer audits and internal inspections; provide evidence and explanation for inspection methods and acceptance criteria.
Train and mentor junior inspectors on inspection techniques, use of measurement tools, NDT fundamentals, and company quality practices while enforcing safety and PPE requirements in the inspection area.
Participate in supplier quality surveillance including receiving inspection of incoming castings/forgings, verifying PO conformance, and initiating supplier corrective actions when required.
Support engineering change initiatives by validating engineering revisions on the shop floor, updating inspection checklists, and ensuring newly released drawings are interpreted and inspected correctly.
Maintain high standards of cleanliness, organization and 5S in the inspection area; ensure inspection fixtures, gauges and CMM areas are free from contaminants that could affect measurement accuracy.
Help develop and refine inspection procedures, work instructions and control plans; contribute practical feedback that improves inspectability and reduces downstream rework.
Operate basic lab instruments and perform metallurgical sample preparations or hardness checks when required, and coordinate with metallurgists for advanced material analysis.
Participate in internal and external quality audits, demonstrate compliance to auditors, and assist with corrective action implementation and follow-up.
Use digital measurement systems and software (MES, QMS, CMM software, spreadsheets) to capture, analyze and present inspection data for management reporting and continuous improvement.
Safely handle and move castings and heavy parts using hoists, cranes, or fixtures during inspection activities, following lifting procedures and maintaining PPE compliance.

Secondary Functions

Support continuous improvement projects (Lean, Kaizen, process capability studies) by providing inspection data, performing measurement system analysis (MSA), and suggesting practical improvements.
Assist in the creation and upkeep of inspection gauges, fixtures and test setups; work with maintenance and tooling to resolve measurement or fixturing issues.
Respond to ad hoc customer quality queries by pulling records, reproducing inspection results, and collaborating with quality engineering to prepare formal responses.
Participate in cross-functional daily production and quality meetings to prioritize inspection activities, schedule FAI work, and address immediate quality concerns.
Maintain calibration logs and coordinate external calibration services to ensure all measurement devices are within tolerance and documented per quality system requirements.
Support supplier development activities by visiting vendor facilities for capability checks, reviewing supplier inspection documentation, and coaching suppliers on acceptance criteria.
Assist production with quick containment actions for suspect parts on the line and help implement interim inspection checkpoints until permanent corrective actions are implemented.
Contribute to the department’s training matrix by recording skill certifications, expiration dates for NDT certifications, and scheduling refresher training.
Aid in maintaining inspection software libraries, 3D CAD models and CMM probe libraries to streamline future inspection programming and reduce setup time.
Participate in safety initiatives and ergonomics assessments for inspection tasks to reduce risk of injury and ensure a safe workplace for inspection personnel.
