Thermal spray operators play a crucial role in surface engineering, applying protective and functional coatings to components used in demanding environments. Using high-energy systems like thermal plasma spray, they enhance surface properties such as corrosion resistance, wear resistance and thermal stability across a wide range of industries.
Training and Responsibilities
Becoming a thermal spray operator requires both technical knowledge and hands-on experience. Operators typically undergo rigorous training, which includes safety procedures, coating theory, material science and machine operation. A standard training pathway may involve over 100 hours of classroom and on-the-job instruction, particularly for complex techniques like plasma spray, flame spray and High-Velocity Oxy-Fuel coating, each requiring specific operational skills and equipment knowledge.
Once qualified, operators are responsible for preparing surfaces through blasting, masking and cleaning. They must configure the equipment according to standard operating procedures and monitor every stage of the spraying process to ensure accurate and consistent results. Coating samples are frequently produced for quality control and validation purposes.
In addition to technical application, operators must interpret process sheets, handle gauges to measure coating thickness and document all procedures for compliance and traceability. Their work directly supports engineers and quality-control teams in optimising surface treatments.
Skills and Safety Standards
Successful thermal spray operators possess a strong understanding of materials, industrial safety and precision measurement. They often work with flammable gases, high-voltage equipment and robotic handling systems, making attention to detail and strict adherence to safety protocols absolutely essential. Communication skills are also important, as operators frequently collaborate with engineers to adjust processes and solve potential issues.
Advanced coatings like thermal plasma spray require precise execution to meet performance standards. Facilities will showcase how skilled operators enable high-performance outcomes through careful process control and expertise.
