Maintain the stock of SS plate for making tanks.

4. Quality Control & Inspection

Ensure fabrication meets standards such as:

o AWS D17.1/17.1M

Coordinate and support NDT activities:

o Radiography Testing (RT)

o Ultrasonic Testing (UT)

o Dye Penetrant Testing (PT)

Monitor dimensional accuracy and tolerance compliance.

5. Shop Floor Supervision

Lead and supervise welders, fitters, grinders, and technicians.

Allocate daily work, monitor productivity, and ensure target achievement.

Troubleshoot fabrication issues and provide technical solutions.

6. Safety & Compliance

Enforce safety practices in the fabrication shop:

o Handling of pressurized systems

o Working at heights and in confined spaces

Conduct safety audits and toolbox talks.

7. Documentation & Reporting

Maintain fabrication records:

o Welding & rolling logs

o Inspection reports

o Material traceability records

o Weld consumable test reports

o PQR test reports

Prepare daily/weekly progress reports.

Coordinate with QA/QC for WPS approval.

Required Qualifications

Bachelor’s Degree or Diploma in Mechanical Engineering.

3–6 years of experience in cryogenic tank fabrication.

Strong knowledge of fabrication processes and welding techniques.

Technical Skills

Expertise in welding processes (TIG/GTAW, SMAW, MIG).

Knowledge of cryogenic tank fabrication.

Familiarity with fabrication codes:

o ASME Section VIII

o AWS D1.6 (preferred)

Ability to read and interpret fabrication drawings.

Hands-on experience with NDT methods.

Soft Skills

Strong leadership and team supervision skills.

Problem-solving and troubleshooting ability.

Attention to detail and quality focus.

Effective communication with cross-functional teams.

Key Performance Indicators (KPIs)

Reduction of weld/rolling/pressing rework.

Fabrication cycle time.

Compliance with quality and safety standards.

On-time completion of fabrication milestones.

Preferred Qualifications

NDT Level II certification (RT/UT/PT/MT).

Experience in LNG, industrial gas, or aerospace sectors.

Knowledge of lean manufacturing.

Work Environment

Primarily shop-floor based with exposure to heavy fabrication.

Involves welding, rolling, pressing, and lifting operations.

May require extended hours during critical project phases.
