Assemblers and Fabricators

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

Assemblers and fabricators typically do the following:

  • Read and understand detailed schematics and blueprints
  • Use hand tools or machines to assemble parts
  • Conduct quality control checks
  • Work closely with designers and engineers in product development 

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 products, 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 systems change the way in which goods are made and affect the jobs of those who make them. Advanced assemblers must be able to work with these new technologies and use them to produce goods.

The job of an assembler or fabricator ranges from very easy to very complicated, requiring a range of knowledge and skills. Skilled assemblers putting together complex machines, for example, read detailed schematics or blueprints 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 and align them properly. Once the parts are properly aligned, they connect them with bolts and screws or 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 to 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 do the same or similar tasks throughout the assembly process.

The following are 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 wings, fuselage, landing gear, rigging and control equipment, or 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 small electronic parts are too small or fragile for human assembly. Much of the remaining 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, or 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, or 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.


Electrical and Electronics Engineers

Electrical engineers design, develop, test, and supervise the manufacturing of electrical equipment such as electric motors, radar and navigation systems, communications systems, or power generation equipment. Electrical engineers also design the electrical systems of automobiles and aircraft.

Electronics engineers design and develop electronic equipment such as broadcast and communications systems, from portable music players to global positioning systems (GPS). Many also work in areas closely related to computer hardware.

Electrical engineers typically do the following:

  • Design new ways to use electrical power to develop or improve products
  • Do detailed calculations to compute manufacturing, construction, and installation standards and specifications
  • Direct manufacturing, installing, and testing to ensure that the product as built meets specifications and codes
  • Investigate complaints from customers or the public, evaluate problems, and recommend solutions
  • Work with project managers on production efforts to ensure projects are completed satisfactorily, on time, and within budget

Electronics engineers typically do the following:

  • Design electronic components, software, products, or systems for commercial, industrial, medical, military, or scientific applications
  • Analyze electrical system requirements, capacity, cost, and customer needs and then develop a system plan
  • Develop maintenance and testing procedures for electronic components and equipment
  • Evaluate systems and recommend repair or design modifications
  • Inspect electronic equipment, instruments, and systems to make sure they meet safety standards and applicable regulations
  • Plan and develop applications and modifications for electronic properties used in parts and systems to improve technical performance

Electronics engineers who work for the federal government research, develop, and evaluate electronic devices used in diverse technologies, such as aviation, computing, transportation, and manufacturing. They work on federal electronic devices and systems, including satellites, flight systems, radar and sonar systems, and communications systems.

The work of electrical engineers and electronics engineers is often similar. Both use engineering and design software and equipment to do engineering tasks. Both types of engineers must also work with other engineers to discuss existing products and possibilities for engineering projects.

Engineers whose work is related exclusively to computer hardware are considered computer hardware engineers. For more information about this occupation, see the profile on computer hardware engineers.


Claims Adjusters, Appraisers, Examiners, and Investigators

Claims adjusters, appraisers, examiners, and investigators evaluate insurance claims. They decide whether an insurance company must pay a claim, and if so, how much.

Claims adjusters, appraisers, examiners, and investigators typically do the following:

  • Investigate, evaluate, and settle insurance claims
  • Determine whether the insurance policy covers the loss claimed
  • Decide the appropriate amount the insurance company should pay
  • Ensure that claims are not fraudulent
  • Contact claimants' doctors or employers to get additional information on questionable claims
  • Confer with legal counsel on claims when needed
  • Keep claims files, such as records of settled claims and an inventory of claims requiring detailed analysis
  • Negotiate settlements
  • Authorize payments

What insurance adjusters, examiners, and investigators do varies by the type of insurance company they work for. They must know a lot about what their company insures. For example, workers in property and casualty insurance must know housing and construction costs to properly evaluate damage from floods or fires. Workers in health insurance must be able to determine which types of treatments are medically necessary and which are questionable. 

Some claims adjusters work as self-employed public adjusters.

Often, they are hired by claimants who prefer not to rely on the insurance company's adjuster. The goal of adjusters working for insurance companies is to save as much money for the company as possible. The goal of a public adjuster working for a claimant is to get the highest possible amount paid to the claimant.

Sometimes, self-employed adjusters are hired by insurance companies in place of hiring adjusters as regular employees. In this case, the self-employed adjusters work in the interest of the insurance company.

Adjusters inspect property damage to determine how much the insurance company should pay for the loss. The property they inspect could be a home, a business, or an automobile.

They interview the claimant and witnesses, inspect the property, and do additional research, such as look at police reports. Adjusters may consult with other workers, such as accountants, architects, construction workers, engineers, lawyers, and physicians, who can offer a more expert evaluation of a claim.

They gather information--including photographs and statements, either written or recorded audio or video--and put it in a report that claims examiners use to evaluate the claim. When the examiner approves policyholder's claim, the claims adjuster negotiates with the claimant and settles the claim.

If the claimant contests the outcome of the claim or the settlement, adjusters work with attorneys and expert witnesses to defend the insurer's position.

Appraisers estimate the cost or value of an insured item. Most appraisers who work for insurance companies and independent adjusting firms are auto damage appraisers. They inspect damaged vehicles after an accident and estimate the cost of repairs. This information then goes to the adjuster, who puts the estimated cost of repairs into the settlement.

Claims examiners review claims after they are submitted to ensure that proper guidelines have been followed by claimants and adjusters. They may assist adjusters with complicated claims or when, for example, a natural disaster occurs and the volume of claims increases.

Most claims examiners work for life or health insurance companies. Examiners who work for health insurance companies review health-related claims to see whether the costs are reasonable, given the diagnosis. After they review the claim, they authorize appropriate payment, deny the claim, or refer the claim to an investigator.

Examiners who work for life insurance companies review the causes of death and pay particular attention to accidents, because most life insurance companies pay additional benefits if a death is accidental. Examiners also may review new applications for life insurance policies to make sure the applicants have no serious illnesses that would make them a high risk to insure.

Insurance investigators handle claims in which the company suspects fraudulent or criminal activity such as arson, staged accidents, or unnecessary medical treatments. The severity of insurance fraud cases varies, from claimants overstating vehicle damage to complicated fraud rings. Investigators often do surveillance work. For example, in the case of a fraudulent workers' compensation claim, an investigator may covertly watch the claimant to see if he or she does activities that would be ruled out by injuries stated in the claim.


Security Guards and Gaming Surveillance Officers

Security guards and gaming surveillance officers patrol and inspect property against fire, theft, vandalism, terrorism, and illegal activity. They monitor people and buildings in an effort to prevent crime.

Security guards and gaming surveillance officers typically do the following:

  • Protect and enforce laws on an employer's property
  • Monitor alarms and closed-circuit TV cameras
  • Control access for employees, visitors, and outside contractors
  • Conduct security checks over a specified area
  • Write comprehensive reports outlining what they observed while on patrol
  • Interview witnesses for later court testimony
  • Detain criminal violators

Guards must remain alert, looking for anything out of the ordinary throughout their shift. In an emergency, guards may call for assistance from police, fire, or ambulance services. Some security guards may be armed.

A security guard's job responsibilities vary from one employer to another. In retail stores, guards protect people, records, merchandise, money, and equipment. They may work with undercover store detectives to prevent theft by customers or employees, detain shoplifting suspects until the police arrive, or patrol parking lots.

In office buildings, banks, hotels, and hospitals, guards maintain order and protect the organization's customers, staff, and property. Guards who work in museums or art galleries protect paintings and exhibits by watching people and inspecting packages entering and leaving the building. In factories, government buildings, and military bases, security guards protect information and products and check the credentials of people and vehicles entering and leaving the premises.

Guards working at universities, in parks, and at sports stadiums do crowd control, supervise parking and seating, and direct traffic. Security guards stationed at the entrance to bars and nightclubs keep under-age people from entering, collect cover charges at the door, and maintain order among customers.

Guards who work as transportation security screeners protect people, transportation equipment, and freight at airports, train stations, and other transportation facilities.

The following are examples of types of security guards and gaming surveillance officers:

Security guards, also called security officers, protect property, enforce laws on the property, deter criminal activity, and deal with other problems. Some guards are assigned a stationary position from which they may monitor alarms or surveillance cameras. Other guards may be assigned a patrol area where they conduct security checks.

Transportation security screeners, many of whom are Transportation Security Administration (TSA) officers, work at air, sea, and rail terminals and other transportation facilities, protecting people, freight, property, and equipment. They use metal detectors, x-ray machines, and other equipment to screen passengers and visitors for weapons and explosives, ensure that nothing is stolen while a vehicle is being loaded or unloaded, and watch for fires and criminals. Some officers work with dogs, which alert them to the presence of dangerous materials, such as bombs.

Armored car guards protect money and valuables during transit. They pick up money or other valuables from businesses and transport them to another location. These guards usually wear bulletproof vests and carry firearms, because transporting money between the truck and the business can be extremely hazardous.

Gaming surveillance officers, also known as surveillance agents and gaming investigators, act as security agents for casino employees, managers, and patrons. Using audio and video equipment in an observation room, they watch casino operations for irregular activities, such as cheating or theft, and monitor compliance with rules, regulations, and laws. They maintain and organize recordings from security cameras, which are sometimes used as evidence in police investigations. In addition, surveillance agents occasionally leave the observation room and walk the casino floor.


Computer, ATM, and Office Machine Repairers

Computer, ATM, and office machine repairers install, fix, and maintain many of the machines that businesses, households, and other consumers use.

Computer, ATM, and office machine repairers typically do the following:

  • Travel to customers' locations in response to service requests
  • Communicate with customers to determine the source of a problem
  • Do administrative tasks, such as completing work order forms
  • Use a variety of tools, such as a multimeter, to help diagnose the problem
  • Install large equipment, such as mainframe computers and ATMs
  • Explain the basic functions of machines and equipment to customers
  • Replace malfunctioning machine parts, such as video cards in desktop computers or keypads on ATM machines
  • Provide preventative maintenance, such as cleaning the internal parts of machines
  • Test newly installed systems to make sure they work properly

In most cases, machines do not break down entirely. Often just one broken part can keep a machine from working properly. Repairers often fix machines by replacing these parts and other defective equipment because it is often less expensive than replacing the entire machine.

Although the work of computer, ATM, and office machine repairers is very similar, the exact tasks differ depending on the type of equipment. For example, computer repairers often must replace desktop parts, such as a motherboard, because of hardware failure. ATM repairers may replace a worn magnetic head on a card reader to allow an ATM to recognize customers' bank cards. Office machine repairers replace parts of office machines that break down from general wear and tear, such as the printheads of inkjet printers.

Some repairers have assigned areas where they do preventive maintenance on a regular basis.

Computer repairers service and repair computer parts, network connections, and computer equipment, such as an external hard drive or computer monitor. Computer repairers must be familiar with various operating systems and commonly used software packages. Some work from repair shops, while others travel to customers' locations.

ATM repairers install and repair automated teller machines and, increasingly, electronic kiosks. They often work with a network of ATMs and travel to ATM locations when they are alerted to a malfunction.

Office machine repairers fix machinery at customers' workplaces because these machines are often large and stationary, such as office printers or copiers. Office machines often need preventive maintenance, such as cleaning, or replacement of commonly used parts as they break down from general wear and tear.
