Operator - Shot Blasting

Reponsibilites

To carry out abrasive blasting operations for structural and precision components of tower cranes and drive systems to achieve the required surface cleanliness, roughness (anchor profile), and preparation standards prior to painting or coating processes. The Shot Blaster ensures proper surface preparation for long-term coating adhesion and corrosion resistance, as per technical and quality specifications (e.g., ISO 8501-1).

Surface Preparation

• Perform shot/grit blasting on fabricated assemblies, machined components, or drive housing components. - Ensure uniform blasting to remove rust, scale, weld slag, oil, and previous coatings.
• Achieve the required surface cleanliness grade (e.g., Sa 2.5 / Sa 3) and anchor profile as specified in the technical specification sheet or paint system.

Pre-Blasting Inspection

• Verify material identity using heat code / part ID prior to blasting.
• Ensure weld joints, oil marks, burrs, and surface damages are appropriately rectified before blasting. - Mask or protect critical surfaces (e.g., machined areas, threads, nameplates) from abrasive media using suitable masking tape or shields.

Equipment Operation & Setup

• Operate manual/semi-auto blasting machines, including blasting pots, hoses, nozzle guns, recovery system, and dust collectors. - Adjust air pressure, nozzle size, and abrasive flow as per job card / SOP.
• Monitor compressor operation and airflow consistency during the job. - Ensure adequate lighting and ventilation inside blasting booths.

Abrasive Media Handling

• Load, monitor, and maintain abrasive blasting media (e.g., steel shots, aluminum oxide).
• Ensure media cleanliness by screening and rejecting contaminated or broken grits. - Inform supervisor for replenishment of low media stock.

Post-Blasting Inspection

• Conduct visual inspection of blasted surface for cleanliness, roughness, or missed areas.
• Reject and reblast areas that show flash rust, oil residue, under-blasting, or excessive pitting.
• Inform quality or paint department once surface is ready for primer application.

Documentation & Traceability

• Record job number, component name, part number, heat number, blasting parameters, date, and operator initials on surface treatment records or Q-log sheet.
• Ensure traceability between raw material heat code and finished component at all stages.
• Tag components clearly post-blasting before transfer to paint.

Maintenance & 5S

• Wear mandatory PPE: blasting helmet with air supply, earplugs, gloves, overalls, and steel-toe boots.
• Follow confined space entry protocols and ventilation system operation.
• Handle used abrasives and waste according to hazardous waste handling norms.
• Follow SOP in case of emergency (e.g., equipment burst, media exposure, fire).

Coordination with Other Teams

• Coordinate with quality, paint, fabrication, and material handling teams for job sequencing.
• Report delay reasons, rejection causes, or equipment readiness status.
• Support continuous improvement or 8D problem-solving activities in case of quality issues.

Qualification & Education Requirements:

• Minimum Education- ITI / NCTVT in Painter / Fitter / Fabrication / Surface Treatment or equivalent
• Preferred Vocational Training- Industrial Blasting, Abrasive Media Handling, Safety in Surface Treatment
• Additional Training / Certifications- SSPC/NACE Blaster Certification Level I (preferred) Internal training on ISO 8501-1, ISO 12944, ISO 11124 blasting standards (if available)
• Work Instruction Comprehension- Must be able to read and interpret job cards, pictorial SOPs, and technical paint/blasting parameters in English or local language

Experience

• Industry Experience- Minimum 2–4 years in surface preparation/blasting operations in heavy fabrication, construction equipment, pressure vessels, or shipbuilding
• Equipment Experience- Hands-on with air pressure blasting pots, suction blasting, recovery & dust extraction systems
• Familiarity with Standards- ISO 8501 (surface preparation), ISO 11124 (abrasives), NACE/SSPC standards
• Safety Experience- Experience in working with full PPE, confined booth operation, ventilation, and safety interlocks

Preferred Skills / Special Skills

• Equipment Usage- Authorized to operate blasting machine, compressor, and recovery systems after safety checks
• Job Execution- Authorized to proceed with blasting after verifying masking, fixture integrity, and job cards
• Process Escalation- Process Escalation
• Surface Readiness Confirmation- Can declare a part ‘ready for paint’ based on visual inspection and blasting standards
• Maintenance Request- Authorized to raise maintenance ticket for preventive or breakdown repairs
• Safety Non-Compliance Reporting- Right to report any violation of EHS protocols or absence of PPE in area
• Job Priority Request- Can inform supervisor regarding job urgency or re-sequencing if dependent process is delayed
