- Environmental Impact: Managing waste from surface preparation and coating application processes.
Level II: Advanced Coating Inspection and Quality Control
1- Advanced Surface Preparation and Coating Systems
- Specialized Surface Preparation: Techniques for preparing non-metallic surfaces (e.g., concrete, plastic, wood).
- Advanced Coating Systems:
- Thermal spray coatings.
- Intumescent coatings (fireproofing).
- Powder coatings.
- High-performance epoxies and polyurethanes.
2- Quality Control and Documentation
- Quality Control Procedures: Ensuring that the entire coating process adheres to project specifications and industry standards.
- Inspection Reports: Writing and reviewing detailed inspection reports, including observations, measurements, and test results.
- Defect Analysis and Troubleshooting: Identifying common coating defects (e.g., blistering, cracking, flaking) and their causes, and how to resolve them.
3- Coating Failures and Remedial Actions
- Common Causes of Coating Failures:
- Poor surface preparation.
- Incorrect application methods.
- Environmental factors (humidity, temperature).
- Remedial Actions: Strategies to repair or reapply coatings after failure.
4- Non-Destructive Testing (NDT) Techniques
- Holiday Testing: Detecting coating defects that may lead to corrosion.
- Ultrasonic Thickness Testing: Measuring the thickness of coatings on complex surfaces without removing the coating.
- Infrared Thermography: Identifying defects in coatings through thermal imaging.
5- Advanced Adhesion and Performance Testing
- Adhesion Testing: Performing advanced adhesion tests such as pull-off adhesion testing.
- Coating Durability Testing: Understanding the methods used to test the long-term performance of coatings, including UV exposure, salt spray testing, and abrasion resistance tests.
