What does a mechanical fitter do?

A mechanical fitter is a tradesperson who builds, repairs and installs components of heavy machinery. Often participating in the production and manufacturing processes, mechanical fitters work with metal to boost the functions of construction and welding equipment. Their professional environment consists of factories, nuclear plants and mining sites. Mechanical fitters often work by themselves, where their direct supervisors evaluate performance during their shifts, and they can take part in group assignments to complete special projects. Their typical responsibilities may include:

  • Reviewing the dimensions from diagrams, blueprints and sketches

  • Determining an order of steps for creating the fabricated components

  • Using grinding and sawing tools to manipulate metal into the desired shapes

  • Attaching the parts to the machines

  • Conducting inspections to ensure tools and machines work properly

  • Identifying malfunctioning equipment and implementing plans to fix them

  • Performing maintenance, such as cleaning and refastening screws

  • Listing building activities and the repairing of tools on work records

  • Adhering to the employer and federal guidelines when handling heavy machinery

  • Documenting findings of safety audits

Skills of a mechanical fitter

The following skills may apply to the profession of a mechanical fitter:

Attention to detail

Mechanical fitters use attention to detail when assembling the fabricated parts. They concentrate on the exact dimensions on the diagram to shape the metal properly, and they focus on the sounds of the equipment to ensure it runs as intended. Detail orientation also allows them to check their work atmosphere thoroughly to feel confident that it meets federal and organisational guidelines for safety.

Manual dexterity

Manual dexterity refers to the simultaneous coordination of eyes and hands, allowing mechanical fitters to operate tools safely and proficiently. Their controlled movements can manipulate the saws and grinders and produce the shapes they want to add to the machines. When installing the parts, professionals use their motor skills to tighten or loosen the components so that it fits correctly inside the equipment. Manual dexterity can also be useful for other responsibilities, such as cleaning the pieces of the machines and reinstalling them to boost their functioning.

Physical fitness

The role of a mechanical fitter can be physically demanding, which is why fitness and stamina can be important. Employees spend most of their shifts using their hands and arms to transport construction equipment and hold it steady to create metal components. They also frequently bend to inspect machines and install the fabricated parts. With physical fitness, mechanical fitters can stand on their feet for extended periods and fulfil their job tasks effectively. They possess the strength to lift heavy materials across their workspaces and hold grinding tools long enough to separate the shapes they need.

Self-sufficient mechanical fitters can work independently and remain productive in the workplace. When they receive new assignments, they can estimate how long each task may take, which enables them to manage their time well and finish the project promptly. The skill also empowers them to perform effectively, with little supervision from their managers.

They're capable of structuring their workdays to prioritise urgent tasks, and they can review their work to ensure it meets the employer's standards. For example, if the project is to create a metal part to modify a forklift's operations, then the mechanical fitter can strategise how much time to devote to assembling, experimenting and installing the product.

Commitment to safety

Knowledge of safety protocols empowers mechanical fitters to execute their job responsibilities while protecting themselves and their coworkers. Their awareness of the differences between functioning and malfunctioning products helps them recognise when a repair is necessary for heavy machines. They understand how to wear protective gear properly, such as goggles, aprons and noise-cancelling headphones. When performing safety audits, mechanical fitters may combine detail orientation and critical thinking to acknowledge when a professional environment is safe. The commitment to safety can also allow them to communicate proper conduct to new or lower-level employees.

How to become a mechanical fitter

Your career path to fulfilling the role of a mechanical fitter may consist of the following steps:

1. Enrol in an apprenticeship

An apprenticeship is the minimum training requirement for mechanical fitter positions. You can learn the fundamentals of engineering, including how to operate heavy machinery, such as sawing and welding tools. The curriculum may also train you on the purpose of the equipment, which can help you identify which piece to use to handle certain tasks in the fields. Apprenticeships often take four years to complete. When you're finished, you can receive Certificate III in Engineering, which authorises you to work in a construction environment.

2. Pursue certifications

Certifications may be requirements for mechanical fitter roles that are more specialised, such as operating forklifts or repairing machines from high places. Obtaining endorsements can expose you to more employment opportunities in the industry. You can also expand on your technical skill set, which can prepare you more for your desired career.

3. Undergo hands-on training

An alternative path to becoming a mechanical fitter is to work as a trainee at an entry-level position in the industry. You can observe the work styles of experienced professionals and receive direction on how to manage the trade. Traineeships may be ideal for aspiring mechanical fitters who have already completed school and are entering the industry from another field.

4. Apply for open positions

Once you're eligible for the profession, you can start searching for open positions in your area. Consider consulting your professional network, such as former classmates, instructors and friends, for insight into companies who may be hiring for your coveted position. It may be helpful to search for vacancies on job profiles, and you check the website of organisations where you want to work.
