Course content

8 Chapters • 39 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Foundations of Repair Work

  • Lesson 1 • Core Hand Tools and Their Uses

    Introduces essential hand tools, their functions, and proper grip techniques. Correct tool selection reduces damage and improves repair quality.

  • Lesson 2 • Materials and Their Properties

    Surveys common repair materials including metals, plastics, wood, and composites. Material knowledge guides adhesive, filler, and fastener selection.

  • Lesson 3 • Introduction to Repair Concepts

    Defines repair versus replacement and explains cost-benefit thinking. Establishes the decision framework used throughout the course.

  • Lesson 4 • Workplace Safety Essentials

    Covers personal protective equipment, hazard identification, and safe work habits. Safety compliance underpins every hands-on task in the course.

  • Lesson 5 • Damage Assessment Fundamentals

    Teaches systematic inspection methods to classify damage severity and scope. Accurate assessment prevents under-repair and unnecessary material waste.

Chapter 2See details

Diagnostic Methods and Problem Identification

  • Lesson 1 • Creating Repair Fault Reports

    Guides students in writing clear, structured fault reports with evidence and recommendations. Quality documentation supports client communication and quality control.

  • Lesson 2 • Interpreting Wear and Failure Patterns

    Teaches recognition of fatigue, corrosion, impact, and thermal failure signatures. Pattern recognition accelerates diagnosis and informs preventive action.

  • Lesson 3 • Using Diagnostic Instruments

    Covers meters, gauges, and testing devices used to measure performance deviations. Instrument accuracy directly affects repair precision.

  • Lesson 4 • Systematic Diagnostic Thinking

    Introduces root-cause analysis and elimination-based reasoning for fault finding. Structured thinking prevents misdiagnosis and repeat failures.

Chapter 3See details

Mechanical Repair Techniques

  • Lesson 1 • Fastener Repair and Replacement

    Addresses stripped threads, seized bolts, and broken fasteners using proven extraction methods. Fastener integrity is critical to structural reassembly.

  • Lesson 2 • Safe Disassembly Procedures

    Establishes sequenced disassembly protocols to avoid secondary damage. Proper sequencing preserves component integrity for reuse.

  • Lesson 3 • Alignment and Calibration After Repair

    Teaches post-repair alignment checks and calibration to restore operational tolerances. Misalignment after reassembly is a leading cause of repeat failures.

  • Lesson 4 • Bearing, Bushing, and Seal Service

    Covers inspection, removal, and installation of bearings, bushings, and seals. Correct installation prevents premature wear and fluid leaks.

  • Lesson 5 • Reassembly Best Practices

    Guides systematic reassembly using correct sequences, torque values, and sealants. Consistent reassembly practice reduces callbacks and warranty claims.

Chapter 4See details

Electrical and Electronic Repair

  • Lesson 1 • Component-Level Electronic Repair

    Introduces PCB inspection, component identification, and soldering for board-level repairs. Component-level repair reduces cost compared to full board replacement.

  • Lesson 2 • Circuit Diagnosis and Testing

    Covers voltage, current, and resistance testing to locate open, short, and ground faults. Accurate circuit diagnosis prevents component replacement errors.

  • Lesson 3 • Wiring Repair and Connector Service

    Teaches splicing, crimping, soldering, and connector replacement to restore wiring integrity. Poor wiring repairs are a primary source of electrical failures.

  • Lesson 4 • Control System Troubleshooting

    Addresses fault codes, sensor signals, and actuator testing in control systems. Control system faults often mask underlying mechanical or electrical issues.

  • Lesson 5 • Electrical Safety and Lockout Procedures

    Establishes energy isolation protocols before any electrical work begins. Lockout compliance is compulsory for safe electrical repair practice.

Chapter 5See details

Surface Repair and Finishing

  • Lesson 1 • Filling and Leveling Damaged Areas

    Teaches filler selection, mixing, application, and shaping to restore surface profiles. Correct filler use eliminates visible repair boundaries after finishing.

  • Lesson 2 • Curing, Polishing, and Protection

    Addresses curing schedules, polishing compounds, and protective topcoats to finalise repairs. Proper curing and protection extend repair life significantly.

  • Lesson 3 • Coating Application Techniques

    Covers brush, roller, and spray application of protective and decorative coatings. Consistent application technique prevents runs, sags, and uneven coverage.

  • Lesson 4 • Colour Matching and Blending

    Introduces colour theory, tinting, and blending techniques for seamless repairs. Visible colour mismatch is the most common customer complaint after surface repair.

  • Lesson 5 • Surface Preparation Methods

    Covers cleaning, degreasing, sanding, and priming to create ideal bonding surfaces. Preparation quality is the single greatest predictor of finish durability.

Chapter 6See details

Structural and Fabrication Repairs

  • Lesson 1 • Adhesive and Composite Bonding

    Introduces structural adhesives and composite patch repairs for non-weldable materials. Bonded repairs can match or exceed original material strength when applied correctly.

  • Lesson 2 • Structural Repair Verification

    Covers non-destructive testing and load testing to confirm repair integrity. Verification prevents premature failure and supports safety compliance.

  • Lesson 3 • Welding for Repair Applications

    Covers MIG, TIG, and stick welding processes selected by material and joint type. Weld quality directly determines the strength of structural repairs.

  • Lesson 4 • Structural Damage Evaluation

    Teaches load path analysis and deformation measurement to assess structural compromise. Structural repairs require higher accuracy than cosmetic work.

  • Lesson 5 • Fabricating Replacement Sections

    Guides cutting, forming, and fitting custom replacement parts when originals are unavailable. Fabrication skills reduce downtime when spare parts cannot be sourced.

Chapter 7See details

Fluid Systems and Leak Repair

  • Lesson 1 • Leak Detection Techniques

    Covers pressure testing, dye injection, and ultrasonic methods to locate leaks precisely. Accurate leak location minimises unnecessary disassembly.

  • Lesson 2 • System Flushing and Recommissioning

    Addresses contamination removal, fluid refill, and pressure testing before returning systems to service. Contaminated fluid causes rapid re-failure of repaired components.

  • Lesson 3 • Valve and Pump Overhaul

    Covers disassembly, seal replacement, and reassembly of valves and pumps. Overhauled components must meet original flow and pressure specifications.

  • Lesson 4 • Pipe and Hose Repair Methods

    Teaches cutting, threading, flaring, and hose replacement for rigid and flexible lines. Correct fitting selection prevents recurrence of pressure-related leaks.

  • Lesson 5 • Fluid System Fundamentals

    Reviews pressure, flow, and fluid properties relevant to repair decisions. Understanding system behaviour is prerequisite to accurate leak diagnosis.

Chapter 8See details

Quality Control and Repair Validation

  • Lesson 1 • Repair Documentation and Handover

    Guides creation of complete repair records, test results, and client handover packages. Thorough documentation protects technicians and informs future maintenance.

  • Lesson 2 • Quality Standards in Repair Work

    Introduces industry quality frameworks and acceptance criteria applicable to repair outputs. Knowing standards prevents under-specification and over-engineering of repairs.

  • Lesson 3 • Root-Cause Verification and Recurrence Prevention

    Confirms that the identified root cause was fully addressed and recurrence risk is eliminated. Unresolved root causes are the primary driver of warranty returns.

  • Lesson 4 • Inspection and Testing Protocols

    Covers functional, dimensional, and performance testing sequences after repair completion. Structured testing catches defects before items are returned to service.

  • Lesson 5 • Continuous Improvement in Repair Practice

    Introduces feedback loops, failure trend analysis, and skill gap identification for ongoing improvement. Continuous improvement transforms competent technicians into repair experts.
