Welding - correct answer Uses extreme heat to join or fuse pieces of metal together.
Pressure Welding - correct answer The metal is heated to a
... [Show More] softened state by electrodes. Pressure is applied and the metal is joined.
Fusion Welding - correct answer Pieces of metal are heated to the melting point, joined together, and allowed to cool.
Weld Root - correct answer The part of the joint where the wire electrode is directed.
Weld Face - correct answer The exposed surface of the weld on the side that has been welded.
Weld Penetration - correct answer Indicated by the height of the exposed surface of the weld on the back side. Full weld penetration is needed to assure maximum weld strength.
Burn Mark - correct answer An indication of good weld penetration.
Burn-Through - correct answer Results from penetrating too much into the lower base metal, which burns a hole through the back side of the metal.
Weld Legs - correct answer The width and height of the weld bead.
Weld Throat - correct answer Refers to the depth of the triangular cross section of the weld.
Joint Fit-Up - correct answer Refers to holding work pieces tightly together, in alignment to prepare for welding.
Metal Inert Gas Welding (MIG) - correct answer Offers more advantages than other methods for welding high-strength steels and high-strength, low alloy steel component parts used in modern cars.
Tungsten Inert Gas (TIG) - correct answer Uses a handheld rod and gas-shielded arc, is often recommended when welding aluminum alloy body panels
Heat Effect Zone - correct answer The area around the weld that becomes adversely hot.
Welding Blankets - correct answer Thick covers made of fire-resistant cloth for protecting vehicle surfaces from heat, sparks, and weld splatter.
Electronic Shielding - correct answer Needed when welding near on-board computers and sensor wiring.
DC Reverse Polarity - correct answer Means the wire (electrode) is positive and the workpiece is negative.
Welding Filter Lens - correct answer Sometimes called a filter plate, a shaded glass welding helmet insert for protecting your eyes from ultraviolet burns.
Welding Current - correct answer Affects the base metal penetration depth, the speed at which the wire is melted, arc stability, and the amount of weld splatter.
Undercutting - correct answer Producing a weld surface level lower than base metal.
Heat Sink Compound - correct answer A paste that can be applied to parts to absorb heat and prevent warpage.
Flat Welding - correct answer Means the pieces are parallel with the bench or shop floor. [Show Less]
