Hard Skills
AdvancedRotary Piercing Mill OperationThe ability to operate and monitor the machinery that transforms solid copper billets into seamless hollow shells using high-pressure rollers and piercing plugs.
IntermediateThermal Management and ControlRegulating the temperature of the billets and machinery components to ensure the copper is at the ideal plasticity for piercing without causing material degradation.
IntermediateDimensional Quality ControlUsing precision measuring tools such as ultrasonic gauges and micrometers to verify wall thickness, eccentricity, and outer diameter of pierced copper shells.
AdvancedMachine Setup and Tooling AlignmentThe technical skill required to configure rolls, guides, and mandrels for specific billet sizes and tube specifications.
AdvancedMechanical TroubleshootingIdentifying and diagnosing irregularities in the piercing process such as vibrations, unusual noise, or surface defects in real-time.
