What Assemblers and Fabricators Do
Assemblers and fabricators build finished products and the parts that go into them. They use handtools and machines to make vehicles, toys, electronic devices, 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 handtools or machines to assemble parts
- Conduct quality control checks
- Clean and maintain work area and equipment, including tools
Assemblers and fabricators need a range of knowledge and skills. For example, assemblers putting together complex machines must be able to read detailed schematics. After determining how parts should connect, they use handtools or power tools to trim, cut, and make other adjustments to fit components together. When the parts are properly aligned, they connect them with bolts and screws, or they weld or solder pieces together.
Assemblers look for faulty components and mistakes throughout the assembly process. Such assessments help to ensure quality by allowing assemblers to fix problems before defective products are made.
Modern manufacturing systems use robots, computers, and other technologies. These systems use teams of workers to produce entire products or components.
Assemblers and fabricators may also be involved in product development. Designers and engineers may 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 in doing the same or similar tasks throughout the manufacturing 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, missiles, or space vehicles. These parts include the wings, landing gear, and heating and ventilating systems.
Coil winders, tapers, and finishers roll wire curs of electrical components used in electric and electronic products, including resistors, transformers, and electric motors. Using handtools, these workers also attach and trim coils or insulation.
Electrical and electronic equipment assemblers build products such as computers, electric motors, and sensing equipment. Unlike in industries with automated systems, much of the small-scale production of electronic devices for aircraft, military systems, and medical equipment must be done by hand. These workers use devices such as soldering irons.
Electromechanical equipment assemblers make and modify mechanical devices that run on electricity, such as household appliances, computer tomography scanners, and vending machines. These workers use tools such as rulers, rivet guns, and soldering irons.
Engine and machine assemblers construct and rebuild motors, turbines, and machines used in automobiles, construction and mining equipment, and power generators.
Fiberglass laminators and fabricators overlay fiberglass onto molds, forming protective surfaces for boat decks and hulls, golf cart bodies, and other products.
Structural metal fabricators and fitters cut, align, and fit together structural metal parts and may help weld or rivet the parts together.
Team assemblers rotate through different tasks on an assembly line, rather than specializing in a single task. Team members may decide how work is assigned and tasks are completed.
Timing device assemblers, adjusters, and calibrators manufacture or modify instruments that require precise measurement of time, such as clocks, watches, and chronometers.
Work Environment
Assemblers and fabricators held about 2.0 million jobs in 2022. Employment in the detailed occupations that make up assemblers and fabricators was distributed as follows:
| Miscellaneous assemblers and fabricators | 1,500,400 |
| Electrical, electronic, and electromechanical assemblers, except coil winders, tapers, and finishers | 282,900 |
| Structural metal fabricators and fitters | 59,600 |
| Engine and other machine assemblers | 50,900 |
| Aircraft structure, surfaces, rigging, and systems assemblers | 33,900 |
| Fiberglass laminators and fabricators | 22,600 |
| Coil winders, tapers, and finishers | 11,100 |
| Timing device assemblers and adjusters | 400 |
The largest employers of assemblers and fabricators were as follows:
| Transportation equipment manufacturing | 25% |
| Temporary help services | 12 |
| Machinery manufacturing | 9 |
| Computer and electronic product manufacturing | 8 |
| Fabricated metal product manufacturing | 8 |
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.
Injuries and Illnesses
Some assemblers come into contact with potentially dangerous chemicals or fumes, but ventilation systems usually minimize any harmful effects. Other assemblers 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; these workers must wear protective gear, such as gloves and long sleeves, and must use respirators for safety.
Work Schedules
Most assemblers and fabricators work full time. Some assemblers and fabricators work in shifts, which may require evening, weekend, and night work.
Getting Started
How to Become an Assembler or Fabricator
The education and qualifications typically needed to enter these occupations vary by industry and employer. Although a high school diploma is enough for most jobs, experience and training are needed for advanced assembly work.
Education
Assemblers and fabricators typically need a high school diploma or equivalent to enter the occupation.
Training
Workers typically receive several months of on-the-job training, sometimes including employer-sponsored technical instruction.
Skilled assemblers and fabricators may need special training or an associate’s degree, depending on the employer. For example, workers in electrical, electronic, and aircraft and motor vehicle products manufacturing typically need postsecondary education. Apprenticeship programs are also available.
Licenses, Certifications, and Registrations
The Fabricators & Manufacturers Association, International (FMA) offers certificates and training programs in fabrication, coil processing, and other related topics. Although not required, these credentials demonstrate competence and professionalism and may help a candidate advance in the occupation.
In addition, many employers, especially those in the aerospace and defense industries, require electrical and electronic assembly workers to have certifications in soldering. The Association Connecting Electronics Industries, also known as IPC, offers a number of certification programs related to electronic assembly and soldering.
Advancement
Experienced assemblers and fabricators may advance to become a supervisor or manager.
Job Outlook
Overall employment of assemblers and fabricators is projected to decline 6 percent from 2022 to 2032.
Despite declining employment, about 188,600 openings for assemblers and fabricators are projected each year, on average, over the decade. All of those openings are expected to result from the need to replace workers who transfer to other occupations or exit the labor force, such as to retire.
Employment
Projected employment of assemblers and fabricators varies by occupation (see table).
In general, employment of assemblers and fabricators is projected to decline or have limited growth 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 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 increasing efficiency by working alongside robots, also known as “collaborative robotics,” which may reduce the demand for some assemblers and fabricators.
Changes in the cost of operations both in the United States and abroad may encourage some manufacturers to bring back production that was previously sent offshore. However, because new facilities in the United States likely will incorporate more automation technologies, they may require less labor overall and may require workers to have high-level skills.
