Welder (Process Piping & Structural)

About the Role

We are seeking a qualified and detail-oriented Welder to join our site installation and fabrication team. In this role, you will carry out high-quality welding on stainless steel (SS) and carbon steel (CS) process piping systems, as well as structural steel frameworks across process and pharmaceutical plant facilities.

Key Responsibilities

• Piping Welding (GTAW / TIG): Perform full-penetration GTAW root pass, fill, and cap welding on Stainless Steel (SS304/SS316L) and Carbon Steel (CS) process pipes in various positions (e.g., 2G, 5G, 6G).
• Purge Gas Management: Ensure proper internal backing gas (Argon) purging setups for stainless steel piping to prevent oxidation, sugaring, or internal root contamination.
• Structural Steel Welding (SMAW): Execute manual metal arc (SMAW / Shielded Metal Arc) welding on structural steel supports, platforms, pipe racks, skids, and secondary brackets in accordance with approved Welding Procedure Specifications (WPS).
• Welding Equipment & Consumable Control: Set up, operate, and maintain welding machines, TIG torches, regulators, gas hoses, and grounding clamps. Correctly select, handle, and store welding consumables (filler wires, flux-coated electrodes, and baking ovens).
• Inspection & Quality Compliance: Clean, deburr, and prepare weld joints; inspect finished welds visually for surface defects (porosity, undercut, lack of fusion, cracks) to ensure 100% compliance with NDT (RT/PT/VT) acceptance criteria.
• Site Coordination & Safety: Follow daily site Permit-to-Work (PTW) protocols, hot-work safety procedures, fire watch standards, and cleanroom/GMP plant housekeeping requirements.

Requirements

• Qualifications & Certifications:

  • Qualified welder holding valid Welder Performance Qualification (WPQ / 6G certification) in:

    • GTAW (TIG) for Stainless Steel (SS) piping.
    • GTAW (TIG) for Carbon Steel (CS) piping.
    • SMAW (Arc) for Structural Steel.

  • Relevant trade qualification (NITEC, CoreTrade, SEC/SEC(K), or equivalent testing authority certification).

• Experience:

  • Proven experience in welding process plant piping, high-pressure lines, or utility systems.
  • Familiarity with local Workplace Safety & Health (WSH) standards and operational procedures in process plants, refineries, or pharmaceutical facilities is an advantage.

• Technical Skills:

  • Familiar with piping components, welding machine accessories, shielding gases, and welding consumables.
  • Capable of interpreting basic piping isometrics, weld symbols, and WPS sheets.

• Language: Basic English proficiency (capable of understanding site safety instructions, toolbox briefings, and daily work tasks).
