Professional Summary: My Experience as a Quality Control Lab Attendant
I am a committed and detail-oriented Quality Control Lab Attendant (गुणवत्ता नियंत्रण प्रयोगशाला सहायक) with hands-on experience in handling modern testing and inspection equipment. In my role, I assist engineers and quality professionals in ensuring that the materials and components used in manufacturing meet strict standards. My responsibilities include preparing samples, performing tests, maintaining lab instruments, and documenting results as per industry standards like ISO 9001 and ISO/IEC 17025.
Expertise in Universal Testing Machine (UTM) – Ensuring Mechanical Strength of Materials
The Universal Testing Machine (UTM) is one of the most crucial machines in our lab. I use it to conduct tensile and compression tests (खींचने और दबाने की जांच) to determine the mechanical properties of materials like metals and plastics. By carefully mounting specimens and operating the UTM, I gather important data like Ultimate Tensile Strength(UTS), Yield point (Y), and elongation(E). These values are critical in deciding if a material is strong enough for its intended use. I strictly follow ASTM and IS standards and make sure the machine is calibrated regularly for accurate and repeatable results.
Operating Dynamic Hardness Testing Machines – Measuring Resistance and Durability
Hardness testing is essential for evaluating a material's wear resistance and surface durability. I operate Dynamic Hardness Machines like Rockwell Hardness Number (RHN), Vickers, and Brinell Hardness Number (BHN) testers to measure how much a material resists indentation (कठोरता की जाँच). The process involves applying a precise load and measuring the indentation made by an indenter. I regularly verify the machine’s calibration using certified blocks and document results as per ASTM E18 or equivalent standards. My careful testing helps engineers choose materials that will last longer and perform reliably under pressure.
Proficient Use of Bruker Spectrometer – Accurate Chemical Composition Analysis
I am trained in using the Bruker Optical Emission Spectrometer (OES) to analyze the chemical composition (रासायनिक संरचना) of metals. This high-tech machine identifies the presence and percentage of elements like carbon, iron, chromium, manganese, etc., by analyzing light emitted during sparking. I use this data to ensure the metal grade meets client and industry specifications. This fast and highly accurate tool is essential for material certification, and I ensure it is calibrated with reference standards for trustworthy results.
Microscopy and Microstructure Analysis – Studying Materials at the Microscopic Level
Understanding a material’s microstructure (सूक्ष्म संरचना) is critical in quality control. I use a Metallurgical Microscope to examine polished and etched samples. This allows me to identify grain size, phase distribution, and any internal defects like cracks or inclusions. These microscopic features help determine whether the material has been properly heat-treated and if it meets the technical requirements. My ability to prepare and examine samples under the microscope supports accurate failure analysis and root cause investigation.
Skilled Use of Precision Measuring Instruments – Accurate Dimensional Inspections
For daily dimensional inspections, I use high-precision tools such as:
Vernier Calipers – for measuring length, thickness, and internal/external diameters with 0.01 mm accuracy.
Micrometers – ideal for measuring very small components where tight tolerances are critical.
Dial Gauges and Height Gauges – used for depth and alignment checking.
Surface Roughness Testers – To evaluate the surface finish quality of machined components.
Each measurement I perform is compared to engineering drawings and tolerance limits, ensuring that only perfect components proceed to the next stage.
Strict Adherence to ISO Quality Standards and Laboratory Protocols :-
Working in a quality lab means following IS (International Standards) and detailed SOPs (Standard Operating Procedures). Our lab complies with ISO/IEC 17025, which ensures all testing is traceable, calibrated, and accurate. I maintain all logbooks, calibration certificates, and daily reports. I also ensure lab safety by using Personal Protective Equipment (PPE) and maintaining a clean, hazard-free environment. My work supports audits, certifications, and customer satisfaction.
Contribution to the Quality Assurance Process – Supporting Reliable Production
As a Lab Attendant, my job directly supports the company’s ability to produce defect-free, high-quality products. Every reading I record and every test I perform contributes to decisions on material approval and process control. My goal is to maintain high standards and help engineers and quality managers solve problems quickly and accurately.
A Reliable Professional in Quality Inspection and Lab Testing :-
I take pride in being a dependable part of the quality team. My practical skills with modern equipment like UTM, hardness testers, spectrometers, microscopes, and precision tools help deliver results that customers and companies can trust. Whether it’s a routine check or a critical test, I carry out every task with professionalism and attention to detail.
I am always open to learning more and contributing to organizations where quality matters.
