Welding and Cutting Vocabulary Flashcards

Welding and Cutting Vocabulary

Auto-darkening helmet: Enhances visibility by remaining clear until the welding arc is struck, eliminating visibility issues.
Bead: Refers to a deposit of filler metal created from a single welding pass.
Brazing: A method for joining metals using a filler metal without melting the base materials, allowing for the combination of similar or dissimilar metals.
Butt joint: A joint configuration where the gap between two panels equals the thickness of the panels themselves.
Butt joint with an insert: Features panels aligned edge-to-edge with another panel inserted for support.
Contact tube: A vital component in MIG welding that connects the welding gun to the wire, ensuring good electrical conductivity.
Continuous weld: Characterized by an uninterrupted weld bead, providing consistency in the join.
Duty cycle: Indicates the operational time of a welding machine over a 10-minute period at a specific heat setting, expressed as a percentage.
Electrode extension (stickout): The length of the welding wire that extends beyond the contact tube of the welding gun.
Fit up: Requires tight fitting of lap welded panels with no gaps to ensure a proper weld.
Flux-cored arc welding: A type of welding process that utilizes wire-feed without conventional shielding gas.
Flux colored wire: A hollow wire that contains a flux core, used in welding applications.
Gun orientation: Refers to the angle at which the welding gun is held relative to the workpiece, affecting the quality of the weld.
Lap joint: Involves the bonding of one metal panel over another, providing a strong connection.
Melt through: Occurs when excess heat from welding melts the base metal, creating unintended holes.
Metal inert gas welding (MIG): A process that joins metals using an electric arc for heating and fusing.
Nozzle: Directs the flow of shielding gas around the welding wire, essential for protecting the weld area.
Penetration: The depth to which the base metal is melted during the welding process, critical for weld strength.
Plug welds: Created through a hole in one lapped metal piece over another, used to replicate factory-style spot welds.
Push-pull wire feeder: Also called a spool gun, it incorporates a motor in the gun for pulling wire while drive rollers push through the machine.
Resistance welding: Involves using electrical resistance to generate heat for melting metal panels together.
Rosebud tip: Attachments for acetylene torches, used primarily for heating steel with a diffusing flame.
Shade: A glass lens in welding helmets that protects from harmful infrared and ultraviolet light.
Skip welding: A welding technique involving strategic placement of welds to create a continuous bead after filling initial gaps.
Slag: The nonmetallic residue formed on top of molten metal during welding, which must be removed for clear joints.
Spatter: Residual molten metal projections that occur during the welding process, which can affect the surrounding areas.
Spot weld: A weld created by clamping two metal panels together and applying heat from two electrodes.
Stick out: Same as electrode extension; it defines how much wire is extended from the welding gun's contact tube.
Stitch weld: A series of short, continuous welds about 3/4 inch long, used for joining sheets of metal.
Temperature crayon: A tool used to measure temperature which melts at a designated temperature, indicating heat levels.
TIG welding: Stands for Tungsten Inert Gas Welding, where a non-consumable tungsten electrode is used, providing precision in the welding process.
Travel direction: The path in which the welding gun is moved to create the weld, influencing the weld quality.
Travel speed: Refers to the speed at which the welding gun is moved during the welding operation.
Tungsten inert gas welding: Distinct from wire-feed methods due to the use of a hand-fed rod as consumable filler material.
Weld bonding: A technique combining adhesive with squeeze-type resistance spot welding for enhanced joint strength.
Weld nugget: The small area where metals are fused together during the welding process, vital for joint integrity.
Weld puddle: The molten metal created during welding, essential for successful joins.
Weld-through primer: A zinc-rich coating applied to overlapped panels before welding, providing protection against corrosion.
