Key Responsibilities:

• • Assist in the fabrication and assembly of rectangular and round ducts, fittings, and HVAC enclosures from sheet metal materials (galvanized steel, aluminum, stainless steel).

  • Operate basic workshop equipment such as shears, brakes, rollers, drills, and hand tools under supervision.

  • Learn to read and interpret HVAC duct layout drawings, fabrication sketches, and job orders.

  • Support the preparation and layout of materials for cutting and forming based on dimensions and tolerances.

  • Participate in spot welding, riveting, fastening, and sealant application during duct assembly.

  • Help with transport, alignment, and fitting of ducts during onboard installation phases.

  • Ensure all parts are fabricated and assembled in accordance with QA/QC guidelines and HVAC standards.

  • Keep the work area organized and comply with workshop safety procedures and PPE requirements.

  • Assist in cleaning and finishing ducts, applying insulation, or fitting flanges and gaskets as needed.

  • Report defective tools or material shortages to the supervisor.

Key Focus Areas:

1. Fabrication Support
   – Provide hands-on help in sheet metal cutting, shaping, and duct assembly processes.

2. Drawing Interpretation
   – Begin learning how to read fabrication drawings and HVAC duct layout plans.

3. Safety and Quality Compliance
