PERCUSSION WELDING: Describes a resistance welding procedure in which heat generated comes from a combination of an arc produced by an electrical discharge and the instantaneous pressure applied during or immediately following the heating.
PLASMA ARC CUTTERS: Describes powerful cutting equipment used for making clean, fast cuts without destroying the properties of high tensile steels.
PLASMA SPRAY PROCESS: Describes the process in which a very high-temperature flame is generated through blowing gas through an electric arc.
PLUG WELD: Describes a type of weld which holds two pieces of metal together through drilling.
PULSE ARC WELDING: Describes a type of welding arc where the arc welding current is interrupted or pulsed as the welding arc progressed.
REINFORCEMENT OF WELD: Describes adding excess metal to the face of a weld to strengthen it.
RESISTANCE WELDING: Describes the procedure of fusing metals using the resistance of the metals to the flow of electricity as the heat source.
SHIELDED ARC: Describes a form of electric welding using a heavy flux-coated electrode.
SHORT ARC: Describes a gas metal- arc process carried out using a low arc voltage, where the arc is continuously interrupted as the molten electrode metal bridges the arc gap.
SOLDER: Describes a compound of two or more metals with a relatively low melting point. Soft solders are alloys of lead and tin, while hard solder are alloys of copper and zinc. When heat is applied, solder joins wires or metal together.
SOLDERING: Describes the procedure of joining two pieces of metal together using either soft or hard solders.
SPOT WELD: Describes the procedure of welding parts together by fusing metal at various spots by passing heavy surges of electricity passed through the parts held in firm contact by electrodes.
SPOT WELDING: Describes a method of welding regarded as the most important in auto body construction, where two pieces of metal are joined at a series of points by a combination of electrically generated heat and pressure.
SPOT-WELDED FLANGE: Describes a sheet metal strip formed into a flange at the panel edge through spot welding.
SPOT-WELD REMOVER: Describes a form of tool used with a hand drill that features a reversible cutting blade used to cut out weld spots without causing damage to the sheet metal material.
SPRAY ARC: Describes a form of gas metal arc welding in which the arc voltage is set very high to allow for the continuous transfer of the electrode metal in small globules.
TACKING: Describes provisionally attaching a panel by placing a few welding spots along its outline, after which final spot welding can be carried out.
TACK WELDING: Describes the procedure of provisionally attaching a panel by placing a few spots of weld along its outline with final welding carried out after other actions have been completed.
TIG WELDING: Describes a method of static arc welding method that uses a tungsten electrode.
VERTICAL POSITION: Describes a type of weld where the welding is carried out on a vertical seam on a vertical surface.
ULTRASONIC WELDING: Describes a new and cutting-edge welding procedure used for both metals and plastics where pressure is applied to the parts to be joined, and ultrasonic vibrations are transmitted through the materials. The use of ultrasonic welding has become prevalent as it is fast and capable of producing precise, strong welds
WELD: Describes the procedure of joining two pieces of metal together by raising the area to be joined to a point hot enough for the two sections to melt and flow together.
WELD FACE: Describes the exposed surface of the weld.
WELDING: Describes the procedure of fastening metals together interfusion. The two pieces of metal are heated to a suitable temperature, and they are soldered together. Although there are more than forty different methods of welding spot welding, is most commonly used in automobile production, while arc welding is the first choice for servicing and repairs.
WELDING ROD: /Describes a thin wire which is melted into the metal plates being melded.
WELDING SEQUENCE: Describes the preferred order in which component parts of a structure should be welded.
WELDING WIRE: Describes a form of welding electrode that is fed into the handset from a reel.
