- Metallographic Sample Preparation & Analysis

- Perform full-process metallographic sample preparation including cutting, mounting, grinding, polishing, and etching

- Conduct microstructural observation, grain size rating, phase content analysis, and defect identification (e.g., porosity, inclusions, cracks) using metallurgical microscopes

- Analyze weld penetration depth, heat-affected zone, and weld microstructure of welded joints

- Prepare and archive metallographic specimens; maintain metallographic sample library

- Hardness Testing

- Operate and maintain Brinell, Rockwell, Vickers, and microhardness testers to perform hardness testing on metallic materials

- Select appropriate hardness testing methods and loads based on material type and specification requirements

- Perform gradient and cross-sectional hardness testing (e.g., on welded joints, heat-treated parts)

- Record and analyze hardness data to determine material heat treatment status and process conformance

- Material Mechanical Testing

- Operate universal testing machines to perform tensile testing, obtaining ultimate tensile strength, yield strength, and elongation values

- Perform other mechanical property tests in accordance with ASTM standards

- Organize, analyze, and report test data

- Laboratory Equipment Maintenance & Quality Management

- Perform daily calibration, maintenance, and upkeep of testing equipment

- Maintain laboratory consumables inventory, including hardness test blocks, chemicals, polishing consumables, etc.

- Comply with laboratory safety procedures and 5S management requirements

- Participate in internal laboratory audits and proficiency testing

- Cross-Functional Collaboration

- Collaborate with production,



process, quality, and engineering teams to support process validation and problem-solving

- Participate in failure analysis projects, providing metallographic and hardness testing support

- Support material property validation required for PPAP submissions for new projects
