Crimping Press Operator

Core Responsibilities

• Precision Pre-Bending: Operate the hydraulic crimping press to bend plate edges to the specific radius required for the final pipe diameter.
• Edge Alignment: Ensure perfectly symmetrical bending on both longitudinal edges to prevent peaking, waviness during the subsequent JCO forming process.
• Tooling Setup: Change crimping dies based on the plate thickness and steel grade (e.g., X65, X70, X80).
• Dimensional Verification: Use radius templates and gauges to verify the Crimp Radius and Flat Zone width (which must be minimized to facilitate high-quality SAW welding).
• Surface Protection: Monitor the process to ensure no die marks, indentations, or surface galling occur on the plate edges
• Equipment Monitoring: Perform daily checks on high-pressure hydraulic pumps, cylinder synchronization, and automated plate-feeding conveyors. 

Technical Skill Set

• 
  CNC/HMI Operation: Proficiency in operating automated control systems from manufacturers like Haeusler, SMS Group, or Linsinger.
• Hydraulics Knowledge: Basic understanding of high-pressure hydraulic circuits (often exceeding 300 bar) and proportional valve control.
• Measurement Tools: Expert use of radius templates, digital callipers

Key Qualifications

• Education: ITI (Fitter/Mechanical) or a Diploma in Mechanical Engineering.
• Experience: 3+-8 years of experience specifically in Crimping or Pre-bending within an LSAW or UOE pipe mill.

• Industry Background: Candidates from similar industries are highly preferred due to their familiarity with high-strength API-grade steels. 

 Preferred Attributes

• Understanding how edge-bending affects the Heat Affected Zone (HAZ) during later welding stages.
• Strict adherence to Lock-Out Tag-Out (LOTO) and safety protocols, as the crimping press involves high-force pinch points.
• Zero-Defect Mindset: Proactive identification of plate laminations or edge defects that become visible only after the bending stress is applied.

Employer-Specific Context

• Strict focus on minimizing the unbent flat edge to ensure a perfect circular profile at the weld seam
• Integration with automated data logging to track Crimping Force per plate per stroke
• Focus on high-speed throughput and rapid die changeovers to maintain aggressive production schedules.
