Dual Wire Sub Arc Welder

Dual Wire Submerged Arc Welder

Dual Wire Submerged Arc (Subarc or SAW) Welder operates heavy-duty mechanized welding equipment to fuse thick metal plates. They set up parameters to feed two consumable wires simultaneously into a single molten weld puddle beneath a blanket of granular flux. This role requires precision machine calibration for deep penetration and high deposition rates.

Core Responsibilities

• Equipment Setup:
  Thread continuous twin wires through feed rolls, set electrode angles, and calibrate variables (current, voltage, travel speed) per Welding Procedure Specifications (WPS).
• Flux Management:
  Fill and direct hoppers to gravity-feed granular flux over the weld line, protecting the weld from atmospheric contamination.
• Operation & Monitoring:
  Monitor machines and adjust parameters in real-time to maintain synchronization between the wire feed and travel speed.
• Quality Control:
  Visually inspect welds and the surrounding metal for defects, and ensure adherence to project blueprints.
• Post-Weld Processing:
  Remove surplus fused slag, flux, and spatter using brushes, portable grinders, or power chippers between passes.

Required Qualifications

• Experience:
  
  2–5 years of experience operating automatic or semi-automatic submerged arc welding machinery in heavy manufacturing, shipbuilding, or pressure vessel fabrication.
• Technical
  
  Skills:
  
  Ability to read/interpret technical drawings and setup operating charts.
• Certifications:
  
  Certified Welder (CW) or Certified Welding Inspector (CWI) is strongly preferred.
• Physical & Safety Requirements:
  Must be able to wear required Personal Protective Equipment (PPE) and navigate around large, heavy structural fabrications.
