Core Responsibilities

Primary Functions

Perform comprehensive first article, in-process, and final inspections on induction heat-treated components to verify 100% conformance to all engineering drawings and specifications.
Utilize a wide array of precision measuring instruments, including micrometers, calipers, height gauges, profilometers, and various bore gauges, to conduct detailed dimensional analysis.
Execute Rockwell hardness testing on part surfaces and prepared cross-sections to ensure components meet specified hardness ranges and gradient requirements.
Meticulously prepare metallurgical samples by sectioning, mounting, grinding, and polishing specimens for microscopic examination fatores such as case depth, microstructure, and grain size.
Conduct Nital Etch or other temper etch inspection procedures to expertly detect grinding burns, re-hardening, decarburization, or other thermal processing defects.
Interpret complex engineering drawings, blueprints, and technical specifications, demonstrating a strong command of Geometric Dimensioning and Tolerancing (GD&T).
Set up, calibrate, and maintain all inspection equipment and metallurgical laboratory apparatus to ensure the accuracy, precision, and repeatability of measurements.
Diligently and accurately document all inspection results, test data, and qualitative findings in quality logs, ERP systems, and formal inspection reports.
Systematically identify, tag, and segregate non-conforming products, and initiate detailed Non-Conformance Reports (NCRs) in accordance with company and industry procedures.
Collaborate proactively with Production, Engineering, and Materials teams to investigate the root cause of defects and participate in developing effective Corrective and Preventive Actions (CAPAs).
Verify and audit induction hardening machine parameters, process travelers, and operational documentation to ensure strict alignment with the approved manufacturing plan.
Conduct thorough visual inspections under various lighting conditions to identify surface imperfections such as cracks, pitting, quench failures, or other discontinuities.
Operate and interpret results from Non-Destructive Testing (NDT) equipment, such as Magnetic Particle Inspection (MPI), to detect surface and near-surface flaws.
Evaluate the microstructure of heat-treated materials against established photographic standards and specifications to confirm that the proper metallurgical transformation has occurred.
Perform destructive testing as required by the quality plan to validate the integrity of the induction hardening process on lot samples or sacrificial test pieces.
Review and approve supplier and outside processor certifications, ensuring all required documentation and test results comply with purchasing and engineering requirements.

Secondary Functions

Support the Quality Engineering team by collecting and organizing data for Statistical Process Control (SPC) charts and process capability studies.
Contribute to the continuous improvement of inspection methods, work instructions, and quality control procedures to enhance efficiency and effectiveness.
Collaborate with the Materials Review Board (MRB) by providing detailed data, samples, and technical insights to aid in the disposition of non-conforming material.
Participate actively in department meetings, safety briefings, and Kaizen events to drive a culture of quality and continuous improvement across the organization.
Assist in the training and mentoring of junior inspectors and production operators on critical quality standards, inspection techniques, and the proper use of gauging.
Support internal, customer, and third-party audits (e.g., NADCAP, AS9100) by retrieving records, demonstrating procedures, and answering technical questions.
Adhere to all workplace safety regulations, champion 5S/6S principles to maintain a clean and organized work station, and utilize all required Personal Protective Equipment (PPE).
