Mechanical fitters fit and assemble metal parts to fabricate production machines and other equipment. They use a range of tools and engineering techniques to maintain and repair mechanical plant machinery and equipment to operational standards.The mechanical fitter job description entails making both minor and major repairs on various gasoline and diesel-powered equipment, while also carrying out welding and repair.

It also involves performing upgrading, fabrication of equipment and facilities, and other several related job duties.

A mechanical fitter may be a specialist in mechanical fitting, pipe fitting, or steam fitting.

He/she may also work in the heating and cooling industry by helping to maintain and repair systems in commercial or factory settings.

He/she is also responsible for carrying out several day-to-day activities, including creating and reading blueprints and utilizing his/her welding skills in the construction of various structural components according to the blueprints.

Mechanical fitters are also expected to be able to efficiently inspect structural systems based on local and state building codes since they work on commercial and industrial piping systems.

The job of a mechanical fitter falls under the regulation of local and state business codes.

They have to be an expert in the regulation codes to self-inspect their work and ensure that everything is up to standards.

Another duty that is carried out by a mechanical fitter is to assemble structural components to create a finished system, using blueprints as a guide.

A mechanical fitter is also expected to use his/her analytical and problem-solving skills so run tests on structural systems to determine the root cause of the malfunction, devise a plan of action, and troubleshoot these malfunctions by replacing the necessary components.
