Millwrights Trade Test Preparation

Millwrights inspect and maintain all types of electrical / Electronics and mechanical equipment .

About this Course

Millwrights inspect and maintain all types of electrical equipment on machinery and in beneficiation plants.

They are also responsible for the mechanical maintenance of machinery, including the assembling and fitting of new components and equipment.

The Millwright trade is a dual trade.

The following modules are done during training:

3 (Three) Weeks Trade Test Preparation

During Final Training, learners receive intensive training to prepare them for the Trade Test. Training during this period includes all modules trained in during the Basic, Advanced and Electronic training phases.

Additional electronic modules can also be completed during this period should his/her company request/require this:

  • Test an amplifier.
  • Using a transistor as a switch.
  • Test multi-vibrators.
  • Identify operational amplifiers.
  • Construct a continuity tester.
  • Test a field effect transistor.
  • Test logic gates.
  • Fault-find circuits.
  • Test electronic systems.

For more information and specific modules, please feel free to contact Renovah Artiscan College.

Any part of the course can also be done as per client specification.

The electronic course can also be done as a separate course (see Additional Courses).
