• Interpret isometric drawings, P&IDs, and welding procedures (WPS).
• Maintain proper welding parameters and ensure joint alignment and penetration quality.
• Conduct root pass, fill, and cap welding with precision to meet inspection criteria.
• Follow strict safety protocols related to welding, confined spaces, and hot work.

Radiography & Ultrasonic Testing Duties:

• Set up and operate industrial radiography (X-ray/Gamma ray) and ultrasonic testing equipment to examine welded joints for internal defects.
• Interpret radiographic films and UT results to identify cracks, porosity, inclusions, and other discontinuities.
• Prepare detailed inspection reports and maintain traceable records of all testing results.
• Ensure NDT activities comply with ASNT SNT-TC-1A, ISO 9712, or equivalent certification standards.
• Coordinate with QA/QC teams, project engineers, and third-party inspectors for weld acceptance.
• Calibrate and maintain NDT equipment in good working condition.

• NDT Level II or III in Radiography (RT) and Ultrasonic Testing (UT) per ASNT or ISO 9712
• Experience: Minimum 3–5 years in chilled water piping, HVAC, or industrial piping systems.
• Familiarity with materials such as CS, SS, CuNi, and HDPE (fusion joints) preferred.
• Strong understanding of QA/QC documentation, weld maps, and inspection test plans.

Skills:

• Excellent technical and analytical skills.
• Proficient in interpreting welding symbols and inspection codes.
• Strong attention to detail and safety awareness.
• Ability to work independently and as part of a multidisciplinary team.

Work Conditions:

• Work may involve confined spaces, heights, and outdoor environments.
• Must comply with site HSE regulations and permit-to-work systems.
