Our Welding Process

Project Review & Planning

Every project begins with a detailed review of engineering drawings, welding procedures, material specifications, and client requirements to ensure the correct welding methodology is selected.

Material Preparation

Components are accurately cut, bevelled, aligned, and assembled before welding to achieve precise fit-up and consistent weld quality.

Certified Coded Welding

Our qualified welders carry out welding using approved procedures and processes, including:

  • MIG (GMAW)
  • TIG (GTAW)
  • MMA / Stick Welding (SMAW)
  • Flux-Cored Arc Welding (FCAW)

The welding process is selected based on the material type, service conditions, and project specifications.

Inspection & Quality Assurance

All completed welds undergo thorough visual inspection and, where required, are verified using advanced Non-Destructive Testing (NDT) techniques, including:

  • Visual Inspection (VT)
  • Ultrasonic Testing (UT)
  • Magnetic Particle Inspection (MPI)
  • Dye Penetrant Inspection (DPI/PT)
  • Radiographic Testing (RT)

This ensures every weld complies with applicable codes, project specifications, and quality requirements.

Documentation & Certification

Upon completion, we provide comprehensive documentation, including welding records, inspection reports, quality assurance documentation, and certification to support project handover and regulatory compliance.
