Fitter Job Description

Fitters construct and assemble mechanical systems. These systems could be factory machines or the piping that carries the chemicals involved in the manufacturing process. Some fitters choose to specialize in mechanical fitting, pipefitting, or steamfitting, others work in the heating and cooling industry maintaining and repairing systems in commercial or factory settings. The manufacturing industry is the largest employer of fitters. Fitters thrive on physical, hands-on work in a work environment that doesn’t revolve around a desk. Some factories maintain evening and weekend hours, and heating and cooling companies often maintain a 24/7 schedule, meaning fitters may work nontraditional shifts.

Fitters who are new to the industry or a particular trade are considered apprentices and work under the direct supervision of a journeyman. Apprentices reach the journeyman level after a certain amount of work hours and professional development classes depending on the organization or trade union. All fitters work under the direction of the project foreman. According to the National Bureau of Labor Statistics, the demand for plumbers, pipefitters, and steamfitters is set to rise 16 percent through 2026, much faster than average.


Fitter Duties and Responsibilities

While fitters may have slightly different responsibilities depending on their area of specialization, most of their responsibilities are the same. Important fitter duties and responsibilities based on several fitter job descriptions include:

Construct Structural Components Based on Blueprints

Fitters must be able to create and read blueprints for structural systems and use their welding skills to craft these components from raw material.

Inspect Structural Systems based on Local and State Building Codes

Most fitters work on commercial or industrial piping systems, which fall under the regulation of local and state business codes. They have to be experts in the codes in order to self-inspect their work and make sure everything is up to standard.

Fit Structural Components Together to Create Finished Systems

Using blueprints as a guide, fitters construct their components; the last task is assembling them to create the finished structure.

Troubleshoot and Repair Malfunctioning Systems

Fitters need to use their analytical and problem-solving skills to run tests on structural systems to determine the root cause of the malfunction. They then need to come up with a plan of action and use their welding skills to replace the necessary components.

Perform Regular System Maintenance

Fitters are responsible for creating and implementing a maintenance procedure and schedule for all of the systems under their control. This includes keeping an organized maintenance log.


Fitter Skills

Fitters rely mostly on technical and vocational skills to do their jobs. Fitters need manual dexterity to operate the various hand tools used during their duties, as well as mechanical skills to understand which tools to use and how to use them. Good fitters are problem solvers with strong attention to detail. In addition to these traits and areas of knowledge, the following skills are necessary to find a job as a fitter:

  • Troubleshooting systems using knowledge of how system was designed to perform
  • Solving and repairing system issues using problem-solving skills
  • Welding components out of raw metals
  • Collaborating with other fitters on larger projects


Fitter Tools of the Trade

  • Basic hand and power tools – hammers, drills, saws, etc.
  • Welding tools – to make structural components out of raw materials
  • Computer-aided design (CAD) software – used to create and read blueprints


Fitter Education and Training

Fitters get most of their education from on-the-job training, as most employers only require a high school diploma. Most businesses and trade unions have a paid apprenticeship program that typically lasts 4 to 5 years. In addition to 2,000 hours a year of paid experience, fitters have to take classes such as welding, machine use, mathematics, and reading blueprints. Some states require certain types of fitters, such as pipefitters, to get certified.


Fitter Salary

According to the National Bureau of Labor Statistics, the national median salary for plumbers, pipefitters, and steamfitters is $51,450. Those in the top 10 percent make above $90,530, while those in the bottom 10 percent make below $30,430.
