Class Vocabulary
adherent		The term used to describe an object that is joined to another object with an adhesive.
adhesive		A nonmetallic material used to join two or more materials together.
adhesive bonding		The joining of two or more materials through the use of a nonmetallic material such as liquids, drops, or gels.
assembler		The person who assembles parts.
assembly		The process in which two or more objects are joined together.
assembly line		A production process in which products are mass-produced in stages.
assembly site		The place where assembly is performed.
automated assembly line		A type of assembly line in which the majority of the tasks are performed by automated machines.
automation		The automatic control of equipment, a process, or a system. Automation is an efficient means of assembly.
base metal		The metals to be joined by welding or other fastening methods.
bolt		A cylindrically shaped, threaded device used for fastening parts. Bolts usually have blunt ends and mate with a nut.
brazing		A process in which a filler metal is melted at a temperature above 840°, but below the melting point of the base metals to form a joint between two base metals. Brazing differs from welding because only the filler metal is melted.
brittle		A material's unwillingness to be drawn, stretched, or formed. Brittle materials are likely to break or fracture if they are stretched.
clamp		A device used to hold a tool or workpiece in place against locators.
compressor tool		A tool that uses pressure to perform a task. Common tools that use compressors are nail guns and staple guns.
corrosion		The gradual chemical attack on a material by atmosphere, moisture, or other agents.
curing		The process in which an adhesive undergoes a chemical reaction and becomes a solid. Curing may require pressure, heat, or a specific amount of time.
drill		A tool that drives screws and creates holes. Drills do not contain a clutch and therefore do not control torque.
ergonomics		The study of designing devices to decrease operator discomfort or fatigue and increase productivity.
fabricator		Another term used to describe an assembler.
fastener		A device that holds two or more objects together. A fastener is a bolt or a screw, or even a button or a zipper.
filler metal		Metal added independently of the base metals to a welding process to add strength to the welded joint.
inventory		The storage of raw material, in-process parts, and completed, manufactured products. Excess inventory is considered waste.
jig		A device used to hold a tool in place.
joint		The point at which two materials are joined together.
manual assembly line		A type of assembly line in which the majority of the tasks are performed by assemblers.
mechanical fastening		The joining of two or more materials through the use of fasteners such as nails, bolts, or screws.
nail		A thin, pointed type of fastener that is fastened into an object with a hammer. Nails are typically used with nonmetallic materials.
nail gun		A tool that uses pressure to automatically force a nail into an object.
nut		A component, usually made of metal, with a threaded hole that mates with a bolt. The outer shape of a nut is often six-sided.
properties		A characteristic of a material that distinguishes it from other materials.
screw		A threaded device used for fastening parts or transferring motion.
screwdriver		A tool used to tighten screws.
soldering		A process in which a filler metal is melted at temperatures below 840° to form a joint between two base metals. Soldering is often used for delicate projects such as jewelry and electronics.
staple gun		A tool that uses pressure to automatically force a staple into an object.
strip		A condition in which a screw has damaged threads as a result of too much torque or force applied to it. A stripped screw is ineffective.
structural adhesive		A type of heavy-duty adhesive used for large-scale projects.
torque		The amount of force applied to tighten a screw.
weld defects		Any one of the various defects that can cause a weld to fail. Weld defects include porosity, incomplete fusion, weld cracking, and undercut.
weld metal		The molten metal, that upon solidification, becomes the welded joint.
welding		A joining process that uses heat, pressure, and/or chemicals to fuse two materials together permanently.
workholding		A device used to support, locate, and hold a workpiece. The workholder references the tool performing the operation on the part being held.
wrench		A tool used to hold or twist nuts and bolts.
