Career Search Assemblers and fabricators play an important role in the manufacturing process. They assemble both finished products and the pieces that go into them. The products they assemble using tools, machines, and their hands range from entire airplanes to intricate timing devices. They fabricate and assemble household appliances, automobiles and automobile engines and parts, computers, electronic devices, and more. Changes in technology have transformed the manufacturing and assembly process. Automated manufacturing systems now 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. The more 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, begin by reading 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 properly. Once the parts are properly aligned, they connect them with bolts and screws or by welding or soldering pieces together. Careful 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 more defective products are produced. Electromechanical equipment assemblers assemble and modify electromechanical devices such as household appliances, dynamometers, actuators, or vending machines. Coil winders, tapers, and finishers wind wire coil used in resistors, transformers, generators, and electric motors. Engine and other machine assemblers construct, assemble, or rebuild engines and turbines, and machines used in agriculture, construction, mining, and almost all manufacturing industries, including rolling mills, textiles, paper, and food processing. Aircraft structure, surfaces, rigging, and systems assemblers assemble, fit, fasten, and install parts of airplanes, space vehicles, or missiles, including tails and wings, landing gear, and heating and ventilation systems. Structural metal fabricators and fitters cut, align, and fit together structural metal parts prior to welding or riveting. Fiberglass laminators and fabricators create products made of fiberglass, mainly boat decks and hulls and automobile body parts. Timing device assemblers, adjusters, and calibrators perform precision assembling or adjusting of timing devices within very narrow tolerances. Work environment. The working environment for assemblers and fabricators is improving, but varies by plant and by industry. Many physically difficult tasks have been made much easier through the use of hydraulic and electromechanical equipment, such as manually tightening massive bolts or moving heavy parts into position. Assembly work, however, may still involve long periods of standing or sitting. Earnings vary by industry, geographic region, skill, educational level, and complexity of the machinery operated.
