Glossy quiz Flashcards
Bond
The point where the welding metal metal is joined with the base metal
Brazing
Welding technique uses a filler metal to create a bond. The filler metal is non-Ferris and has a melting point below the melting point of the base metal
Carbon arc welding
A welding method that involves creating an ark between a carbon electrode and a metal
Case hardening
This process hardens the surface of the metal by using inward, diffusion with gases or a liquid before applying heat
Coated electrode
The metal electrode is covered with asbestos, flux, paper or other metals to make the arc more stable and improve the welding metal
Critical temperature
The temperature which the material transitions from one crystalline form to another
Current density
The amount of aires applied per square inch across a particular area
Alloy
A metal made from two or more combined, elements
Annealing
The slow cooling of the metal to reduce internal stresses, make the material softer and change ductility
Arc welding
Is a general term that applies to many kinds of welding. The common denominator is using an arc to create heat. Arc welding may also use other filler materials or pressure to create a weld.
Direct current electrode negative (DCEN)
The metal being welded is the positive pole and the electrode is the negative pole of the arc
Direct current electrode positive ( DCEP)
The world medal is the negative pole and the electrode is the positive pole of the ark
Electric arc
An electrical current that forms in the gap between two electrodes creates an electric arc
Electrode
An electrode conduct the electrical current through a workpiece to create the weld.
There are many types of electrodes, some not all; electrodes are consumed in the welding process
Filler material
This is the metal that is added when making weld
Flame (oxygen) cutting
The chemical action of oxygen applies to the elements in the basement metal at high temperatures cut Ferrous metals
Flame (oxygen) gouging
This message message is used to create a groove in the metal using an oxygen cutting tool
Flame hardening
The metal surface is hardened, using a heated flame followed by a quick quench
Flame softening
This technique makes the metal softer by heating it and then slowly letting it cool down
Flux
This material cleans metals to prepare them for welding
Forehand welding
The flare is aimed at the metal ahead of the completed weld
GCAW stands for
Gas carbon arc welding
The world is accomplished by an electrical arc between a carbon electrode, and the welding metal argon or helium gas provides the shielding
GMAW stands for
Gas metal arc welding (MIG)
The heat from the arc produced between the electrode and the metal results in a weld a gas like helium provides the shielding. This technique is also called metal, inert, gas welding. (MIG)
