Welders are skilled in understanding the compatibility of different types of materials that needs to be welded together, to ensure a proper solid structure comes out of the welding process. These materials include ferrous and non-ferrous metals such as carbon steel and aluminium. Welders are also skilled in understanding settings on various machines and welding rods or welding wire, as well as the setting up of regulators, different types of gases being used in the welding disciplines and how to purge in order to remove oxygen to prevent conditions of porosity.
Mechanical Fitting involves assembly, installation and maintenance of complex machinery used in industries.
The Boilermakers are skilled in reading and interpreting drawings in the manufacturing process of various metal based components. The artisan must have good welding skills and understand the way metal will respond when heat is applied to it by the type of welding being applied; the understanding of malleability of steel is of the highest importance. The artisan must have good working knowledge of rollers bending machines welders and grinders as well as measuring equipment and methods.
Turning involves manufacturing parts that are required for repairs, replacement and fitting for machinery and equipment.
Electricians are equipped with the skill to understand the fundamentals of electricity, measuring instruments, various electrical components, AC machines, DC machines, electronics, PLC and fault finding. A properly skilled electrician is critical for safety for both private households and organisations alike.
The millwright possesses a combination of a fitter and an electrician skill sets, enabling them to install, dismantle, repair, reassemble and move machinery in factories, power plants and construction sites. Additionally, they can perform mechanical and electrical fault finding on machines and equipment, understand engineering standards and the methodology to repair and do preventative maintenance on plants, machines and equipment. The Millwright should also be able to know and identify bearings their applications and how to store and maintain them. Manufacturing of keys and small components are also commonly done by using measuring, marking off equipment drilling machines grinders and hand tools.
Fitter & Turner
A fitter and turner is responsible for studying blueprints, plans, and drawings to be able to construct, assemble, manufacture, and fit parts of machines. This person is also responsible for maintaining and repairing different types of machinery.
Tool Jig & Die Maker
A toolmaker produces precision tools which are used to manufacture metal parts and instruments. They also make tool holders as well as jigs and fixtures which keep metal in place when it is being stamped or drilled. These tools can be controlled mechanically or by a computer.
