Assemblers and fabricators assemble finished products and the parts that go into them. They use tools, machines, and their hands to make engines, computers, aircraft, ships, boats, toys, electronic devices, control panels, and more.

Duties

Assemblers and fabricators typically do the following:

  • Read and understand schematics and blueprints
  • Position or align components and parts either manually or with hoists
  • Use hand tools or machines to assemble parts
  • Conduct quality control checks
  • Clean and maintain work area, tools, and other equipment

Assemblers and fabricators have an important role in the manufacturing process. They assemble both finished products and the pieces that go into them. The products encompass a full range of manufactured goods, including aircraft, toys, household appliances, automobiles, computers, and electronic devices.

Changes in technology have transformed the manufacturing and assembly process. Modern manufacturing systems use robots, computers, programmable motion-control devices, and various sensing technologies. These technological changes affect the way in which goods are made and the jobs of those who make them. Advanced assemblers must be able to work with these new technologies and use them to manufacture goods.

The job of an assembler or fabricator requires a range of knowledge and skills. Skilled assemblers putting together complex machines, for example, read detailed schematics that show how to assemble the machine. After determining how parts should connect, they use hand or power tools to trim, shim, cut, and make other adjustments to fit components together. Once the parts are properly aligned, they connect them with bolts and screws, or they weld or solder pieces together.

Quality control is important throughout the assembly process, so assemblers look for faulty components and mistakes in the assembly process. They help fix problems before defective products are made.

Manufacturing techniques are moving away from traditional assembly line systems toward lean manufacturing systems, which use teams of workers to produce entire products or components. Lean manufacturing has changed the nature of the assemblers’ duties.

It has become more common to involve assemblers and fabricators in product development. Designers and engineers consult manufacturing workers during the design stage to improve product reliability and manufacturing efficiency. Some experienced assemblers work with designers and engineers to build prototypes or test products.

Although most assemblers and fabricators are classified as team assemblers, others specialize in producing one type of product or perform the same or similar tasks throughout the assembly process.

The following are examples of types of assemblers and fabricators:

Aircraft structure, surfaces, rigging, and systems assemblers fit, fasten, and install parts of airplanes, space vehicles, or missiles, such as the wings, fuselage, landing gear, rigging and control equipment, and heating and ventilating systems.

Coil winders, tapers, and finishers wind wire coils of electrical components used in a variety of electric and electronic products, including resistors, transformers, generators, and electric motors.

Electrical and electronic equipment assemblers build products such as electric motors, computers, electronic control devices, and sensing equipment. Automated systems have been put in place because many electronic parts are too small or fragile for human assembly. Much of the work of electrical and electronic assemblers is done by hand during the small-scale production of electronic devices used in all types of aircraft, military systems, and medical equipment. Production by hand requires these workers to use devices such as soldering irons.

Electromechanical equipment assemblers assemble and modify electromechanical devices such as household appliances, computer tomography scanners, or vending machines. The workers use a variety of tools, such as rulers, rivet guns, and soldering irons.

Engine and machine assemblers construct, assemble, and rebuild engines, turbines, and machines used in automobiles, construction and mining equipment, and power generators.

Structural metal fabricators and fitters cut, align, and fit together structural metal parts and may help weld or rivet the parts together.

Fiberglass laminators and fabricators laminate layers of fiberglass on molds to form boat decks and hulls, bodies for golf carts, automobiles, and other products.

Team assemblers work on an assembly line, but they rotate through different tasks, rather than specializing in a single task. The team may decide how the work is assigned and how different tasks are done. Some aspects of lean production, such as rotating tasks and seeking worker input on improving the assembly process, are common to all assembly and fabrication occupations.

Timing device assemblers, adjusters, and calibrators do precision assembling or adjusting of timing devices within very narrow tolerances.

Most assemblers and fabricators work in manufacturing plants, and working conditions vary by plant and by industry. Many physically difficult tasks, such as tightening massive bolts or moving heavy parts into position, have been automated or made easier through the use of power tools. Assembly work, however, may still involve long periods of standing, sitting, or working on ladders, such as in the shipbuilding industry.

Injuries and Illnesses

Some assemblers may come into contact with potentially harmful chemicals or fumes, but ventilation systems normally minimize any harmful effects. Other assemblers may come into contact with oil and grease, and their work areas may be noisy. Fiberglass laminators and fabricators are exposed to fiberglass, which may irritate the skin. Therefore, fiberglass workers must wear gloves and long sleeves and must use respirators for safety.

Work Schedules

Most assemblers and fabricators are employed full time. Some assemblers and fabricators work in shifts, which may require evening, weekend, and night work.

Job Outlook

Overall employment of assemblers and fabricators is projected to decline 11 percent from 2018 to 2028.

Within the manufacturing sector, employment of assemblers and fabricators will be determined largely by the growth or decline in the production of certain manufactured goods. In general, overall employment of assemblers and fabricators is projected to decline because many manufacturing sectors are expected to become more efficient and able to produce more with fewer workers.

In most manufacturing industries, improved processes, tools, and, in some cases, automation will reduce job growth. Increasingly, new advances in robotics have enabled machinery to perform more complex and delicate tasks previously performed by workers. In addition, assemblers and fabricators are increasingly working alongside robots, also known as “collaborative robotics.” These new robots can help workers perform tasks and increase efficiency. However, this increased efficiency may reduce the demand for some assemblers and fabricators.

Cheaper and more advanced robotics, along with the possibility of decreased taxes and regulations, may entice some manufacturers to bring previously offshored production back to the United States. However, the new jobs may be more highly skilled in nature and more dependent upon automated technology.

Advances in three-dimensional printing, also known as additive manufacturing, has the potential to reshape the entire manufacturing sector in the future. Entire parts or even vehicles might be produced in a single build that would require very little assembly or fabrication by hand. This technology is still emerging though, and may not immediately affect the demand for these workers within the next 10 years.

Job Prospects

Qualified applicants, including those with technical vocational training and certification, are likely to have the best job opportunities in growing, high-technology industries, such as aerospace and electro-medical devices manufacturing.

Many job openings are expected to result from the need to replace workers who leave or retire from these large occupations.
