Welding Terms (E & F)
Dear Readers,
Following Terms are commonly used in
Welding works.
Edge Joint - The outer edge of
two plates butted up 90 degrees parallel to each other.
Edge Preparation - Before welding
the edge of a plate or pipe, care is taken to ensure a sound weld. It may be
torch cut or beveled, machined with a grinder, filed, or all three.
Electrode - Electrodes come
either covered with flux, or just bare wire. In the field an electrode is
called a "rod" in stick welding, and "wire" for Mig and
Flux Cored Arc Welding.
Electrode Extension – The length
of electrode extending beyond the end of the contact tube.
Electrode Holder – A hand clamp
that holds a welding rod and conducts electricity out of the rod in DIRECT
CURRENT ELECTRODE NEGATIVE, or into the rod in DIRECT CURRENT ELECTRODE
POSITIVE.
Electron Beam Welding – A welding
process producing coalescence of metals with molten slag which melts the filler
metal and the surfaces of the work to be welded. The molten weld pool is
shielded by the slag, which moves along the full cross section of the joint as
welding progresses.
Electroslag Welding – A welding process producing coalescence of metals with molten slag which melts the filler metal and the surfaces of the work to be welded. The molten weld pool is shielded by the slag, which moves along the full cross section of the joint as welding progresses.
Eutectoid Composition – A mixture
of phases whose composition are determined by the eutectoid point in the solid
region of an equilibrium diagram and whose constituents are formed by eutectoid
reaction.
Face - On plate or pipe welding
there is a ROOT PASS, HOT PASS, FILLER PASS, and CAP. The root penetrates
through the back of the plate, the cap is on the surface which you are welding,
which is the face.
Facing Surface – The surfaces of
materials in contact with each other and joined or about to be joined together.
Fan: Welding machines have a fan
to cool the machine down and keep it from overheating. (Check the Duty Cycle / Working
Hours) Some fans run constantly, while others run "on demand" which
means it comes on when necessary and clicks off when not needed.
Ferrous Metal - Ferrous means
that the metal is iron, or iron with alloys.
Filler Material – The material to
be added in making a welded, brazed, or soldered joint.
Fillet Weld – A weld of
approximately triangular cross section that joins two surfaces approximately at
right angles to each other in a lap joint, T-joint, or corner joint.
Fillet Weld Face - The surface or
top of the weld.
Fillet Weld Leg - From the
intersection of the joint to the end of the weld. There will be a leg for each
plate.
Fillet Weld Toe - Is the end of
the weld at the end of the leg. Again, there will be one for each plate.
Fillet Weld Root - Where the weld
begins at the intersection of the joined plates.
Fillet Weld Throat - The distance
from the root to the face.
Filter Plate – A transparent
plate tinted in varying darkness for use in goggles, helmets, and hand shields
to protect workers from harmful ultraviolet, infrared, and visible radiation.
Flame Spraying – A thermal
spraying process using an oxy-fuel gas flame as the source of heat for melting
the coating material.
Flammable Range – The range over
which a gas at normal temperature (NTP) forms a flammable mixture with air.
Flat Welding Position – A welding
position where the weld axis is approximately horizontal and the weld face lies
in an approximately horizontal plane.
Flashback – A recession of the
flame into or back of the mixing chamber of the torch.
Flashback Arrestor – A device to
limit damage from a flashback by preventing the propagation of the flame front
beyond the point at which the arrestor is installed.
Flash Burn - This is a burn from
the radiation produced from the ULTRAVIOLET rays from the welding arc. It can
burn the skin like sunburn, and even blister the cornea. You do not realize it
until hours later when it feels like someone is rubbing hot sand in your eyes.
Flashing – The violent expulsion
of small metal particles due to arcing during flash butt welding.
Flux – Material used to prevent,
dissolve, or facilitate removal of oxides and other undesirable surface
substances.
Flux Cored Arc Welding (FCAW) –
An arc welding process that produces coalescence of metals by means of tubular
electrode. Shielding gas may or may not be used.
Free Bend Test - Also called a guided bend test, this is a destructive
test. A coupon is cut from a test plate, the weld grinded, then the coupon
(usually 1 ½ "wide by 7" long) is bent in a JIG. It is then VISUALLY
INSPECTED for cracks and defects.
Friction Welding – A solid
welding process which produces coalescence of material by the heat obtained
from a mechanically induced sliding motion between rubbing surfaces. The work
parts are held together under pressure.
Friction Stir Welding – A
solid-state welding process, which produces coalescence of material by the heat
obtained from a mechanically induced rotating motion between tightly butted
surfaces. The work parts are held together under pressure.
Forehand Welding – A welding
technique where the welding torches or gun is pointed toward the direction of
welding.
Fumes - Welding fumes are a
complex mixture of metals metallic oxides, silicates, and fluorides. Fumes are
formed when a metal is heated above its boiling point and its vapors condense
into very fine, particles (solid particulates). Welding fumes generally contain
particles from the electrode and the material being welded
Fusion – The melting together of
filler metal and base metal (substrate), or of base metal only, which results
in coalescence.
