Repairman, Technician

A mechanic is an artisan, skilled tradesperson, or technician who uses tools to build, maintain, or repair machinery. [1]



Most mechanics specialize in a particular field, such as auto body mechanics, air conditioning and refrigeration mechanics, auto mechanics, bicycle mechanics, boiler mechanics, general mechanics, industrial maintenance mechanics (millwrights), motorcycle mechanics, aircraft mechanics, heavy duty equipment mechanics, bus mechanics, truck mechanics, [2] diesel mechanics as well as tank mechanics in the armed services.

A mechanic is typically certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heavy equipment, such as tractors and trailers, while lightweight work is on smaller items, such as automotive engines.

Auto mechanics

Auto mechanics have many trades within. Some may specialize in the electrical aspects, while others may specialize in the mechanical aspects. Other areas include: brakes and steering, suspension, automatic or manual transmission, engine repairs, auto body repairs or diagnosing customer complaints.

An automotive technician, on the other hand, has a wide variety of topics to learn.

In the field of automotive repair, the term "line technician" or "heavy line technician" is a reference to "driveline technician" and is used mainly in dealerships. The term heavy line technician is due to these mechanics specializing in the engine and transmission issues, and they are usually the more experienced mechanics. Light line or line mechanic is more suited to general mechanical issues like water pumps, alternators, power steering, brakes, suspension systems, and other areas of the vehicle. Light line techs will usually move into heavy line tech as they master the job of repair to vehicles. These terms have been used throughout the industry, and vehicle repair involves "applied science", in particular electrical theory, fluid dynamics, chemistry, metallurgy, and physics and an understanding of all areas of current design in vehicles used in North America. The heavy line tech is the jargon used in the industry that would denote a top-level mechanic, and more recently an ASE Master Mechanic with longtime experience, who concentrate on major engine and transmission repairs. "ASE" is the "National Institute for Automotive Excellence". They are the largest organization presently to test and certify mechanics in the US. They have many areas of testing, including engine repair, automatic transmission/manual transaxle, suspension and steering, brakes, heating and air conditioning, and engine performance. They have many other testing and certification programs, including truck specialist and parts specialist.

Automation technician Profession

Automation technicians repair and maintain the computer-controlled systems and robotic devices used within industrial and commercial facilities to reduce human intervention and maximize efficiency. Their duties require knowledge of electronics, mechanics and computers. Automation technicians perform routine diagnostic checks on automated systems, monitor automated systems, isolate problems and perform repairs. If a problem occurs, the technician needs to be able to troubleshoot the issue and determine if the problem is mechanical, electrical or from the computer systems controlling the process. Once the issue has been diagnosed, the technician must repair or replace any necessary components, such as a sensor or electrical wiring. In addition to troubleshooting, Automation technicians design and service control systems ranging from electromechanical devices and systems to high-speed robotics and programmable logic controllers (PLCs). These types of systems include robotic assembly devices, conveyors, batch mixers, electrical distribution systems, and building automation systems. These machines and systems are often found within industrial and manufacturing plants, such as food processing facilities. Alternate job titles include field technician, bench technician, robotics technician, PLC technician, production support technician and maintenance technician.

PLC technicians design, program, repair and maintain programmable logic controller (PLC) systems used within manufacturing and service industries ranging from industrial packaging to commercial car washes and traffic lights.
