  1. 1. A Presentation On Vocational Training At Hindustan Aeronautics Limited Transport Aircraft Division(HAL-TAD) KESHAV SHUKLA 89/16 (V.T. No.) Mechanical 4th year
  2. 2. CONTENTS  INTRODUCTION TO HAL  HAL DIVISIONS AND PRODUCT  ABOUT HAL TAD  PROJECT DISCRIPTION  PROJECT ANALYSIS  PAINTING PROCESS  PROJECT RESULT  CONCLUSION
  3. 3. About HAL Type Public Sector enterprise Industry Aerospace and defence Founded 1940 (in 1964, company took on current name) Headquarters Bangalore, Karnataka, India Chairman T.S. Raju Products Aerospace equipment Military aircraft Communication & Navigation equipment Space systems Revenue ₹15000+ crore Employees 30,000+

  6. 6. About HAL-TAD  Founded - In 1960 to manufacture HS -748  Products mfg. – over 500 aircrafts  Rotables mfg. – 400 types  Extensive facility- for repairing, overhauling, modification
  7. 7. “How to reduce repainting in aircraft equipment and rotables”
  8. 8.  To reduce re-painting we have to focus on following points-  To ensure about previous operation done  Properly follow all aircraft painting standards  Storage of aircraft  Why we painting it. etching Surface treatment N.D.T. Electroplating and masking Priming and painting For etching we have two methods- 1.Chemical stripping 2.Dry stripping
  9. 9. Painting Reasons of painting-:  Protect skin and structure from corrosion.  Top coat provides an abrasion and fluid resisting cover to the primer.  The decorating finish.  To save surfaces from filliform corrosion THE CORROSION WHICH FORMS IN FINE FILAMENT IS KNOWN AS FILLIFORM CORROSION.
  10. 10. Painting The general Process of painting-: Cleaning or degreasing Anodizing or electroplating (as per require) Priming Final paint coating
  11. 11. STRUCTURE OF AIRCRAFT
  12. 12. PAINTING 1.Cleaning -: a) Using PCE [per chloro ethelene] solution b) Use of cotton rags for skin cleaning c) After solvent cleaning we treated it with deoxidine -202, restodine-624 with brush d) After leaving 20 min we wash off with jet pressure of water
  13. 13. Painting 2.Anodizing- it is an electrochemical process that converts the metal surface into decorative durable corrosion-resistant, anodic oxidize finish. • Provide better glue-ability. • Improved paint adhesion. TYPES OF ANODIZING 1. CHROMIC ACID ANODIZING- GOOD FOR TIGHT TOLERANCE PARTS AND PROVIDE PAINT BASE 2. SULFURIC ACID ANODIZING- USED TO ANODIZE HYDRAULIC PARTS 3. HARD ANODIZING- NOT USED IN HAL KANPUR
  14. 14. 3.Priming-: it is a process of surface preparation. a) Wash primer - 1 coat of 0.013 mm b) Epoxy primer – popular for use under urethane & polyurethane coating. Wash primers are water-thin coatings of phosphoric acid in solutions of vinyl butyral resin, alcohol, and other ingredients. Epoxy is a synthetic, thermosetting resin that produces tough, hard, chemical-resistant coatings and adhesives
  15. 15. 4. Painting And Condition Of Painting-:  The topcoat finish is applied to protect the exposed surfaces from corrosion and deterioration.  Paint has three components: 1. Resin as coating material 2. Pigment for color 3. Solvents to reduce viscosity
  16. 16.  Temperature and humidity table HUMIDTY 90g per kg of DA R.H. 57% TEMP. 70° Fahrenheit~21.1°C IF R.H. 49% TEMP. 75° Fahrenheit~23.9°C
  17. 17. Project Result To reduce repainting we have to  follow international painting standards.  Cover and mask the part which we have painted and also those which we have not to paint.  Painting booth should be closed and fulfill all basic needs to paint.
  18. 18. Conclusion  HAL being the premier aircraft manufacturers are not that productive.  The reasons for this are :- # Demotivating workspace environment # Lack of planning in setting up of short term objectives. # Lack of monitoring and regulation. # Multiple Unions that cause disruption of work. # Lack of proper training facilities. # Hiring done only on basis of merit.
