Key Responsibilities
Precision Welding Operations: Perform high-quality TIG / GTAW welding on critical components made of Stainless Steel (SS), Aluminum, Carbon Steel, and exotic alloys like Titanium or Inconel.
Full Argon Purging: Execute back-purging setups using Argon gas for pipe welding to prevent internal oxidation (sugarisation) and ensure a smooth, uniform internal root bead.
Machine & Torch Calibration: Select and sharpen appropriate tungsten electrodes (., thoriated, ceriated, lanthanated). Calibrate high-frequency welding machines, adjusting amperage, post-flow gas timing, and flow meters precisely.
Blueprints & Weld Symbols: Read and interpret advanced engineering drawings, blueprints, and Welding Procedure Specifications (WPS) to understand specific joint designs and dimensional tolerances.
Joint Preparation: Cut, bevel, clean, and fit-up workpieces using specialized tools. Ensure the welding zone is completely free of moisture, grease, or oxides before striking an arc.
Radiographic Quality Checks: Ensure all critical joints meet stringent non-destructive testing (NDT) standards, including X-ray/radiography, dye penetrant testing (DPT), and visual inspections.
Safety & Cleanliness: Maintain an ultra-clean workspace (critical for high-alloy welding). Adhere to rigorous safety protocols, including wearing correct shade auto-darkening helmets, leather safety gear, and respiratory protection when working with toxic fumes.
