Repairing Course

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 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 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 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 1 • Filling and Levelling 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 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 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 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.
