Dear Readers,
Following terms are commonly used in Welding works.
Arc Blow – The deflection of an electric arc from its normal path because of magnetic forces.
Arc Cutting – A group of thermal cutting
processes that severs or removes metal by melting with the heat of an arc
between an electrode and the work piece.
Arc Gouging – An arc cutting procedure used to
form a bevel or groove.
Arc Length – The distance from the tip of the
electrode or wire to the work piece.
Arc Time – The time during which an arc is
maintained.
Arc Voltage – The voltage across the welding
arc.
Arc Welding – A group of welding processes
which produces coalescence of metals by heating them with an arc, with or
without the application of pressure and with or without the use of filler
metal.
Arc Welding Deposition Efficiency (%) – The
ratio of the weight of filler metal deposited to the weight of filler metal
melted.
Arc Welding Electrode – A part of the welding
system through which current is conducted that ends at the arc.
Atomic Hydrogen Welding – An arc welding
process which produces coalescence of metals by heating them with an electric
arc maintained between two metal electrodes in an atmosphere of hydrogen.
Autogenous Weld – A fusion weld made without
the addition of filler metal.
Automatic – The control of a process with
equipment that requires little or no observation of the welding and no manual
adjustment of the equipment controls.
Back Gouging – The removal of weld metal and
base metal from the other side of a partially welded joint to assure complete
penetration upon subsequent welding from that side.
Backfire – The momentary recession of the
flame into the welding or cutting tip followed by reappearance or complete
extinction of the flame.
Backhand Welding – A welding technique where
the welding torch or gun is directed opposite to the direction of welding.
Backing – A material (base metal, weld metal,
or granular material) placed at the root of a weld joint for the purpose of
supporting molten weld metal.
Backup Strip — is a strip or section of steel
butted up to an open gap between two pieces of steel.
Backing Gas – A shielding gas used on the
underside of a weld bead to protect it from atmospheric contamination.
Back-Step Sequence – A longitudinal sequence
in which the weld bead increments are deposited in the direction opposite to
the progress of welding the joint.
Base Metal (material) – The metal (material)
to be welded, brazed, soldered, or cut. See also substrate.
Bend Radius – Radius of curvature on a bend
specimen or bent area of a formed part. Measured on the inside of a bend.
Bevel – An angled edge preparation.
Blown-up - what you will be if you weld or cut
on containers with fumes. NEVER weld or cut on any container unless it is new
or you know it has been cleaned and safety certified! Containers can be toxic,
flammable, or explosive.
Braze Welding – A method of welding by using a
filler metal, having a liquidus above 840 °F (450 °C) and below the solidus of
the base metals.
Brazing – A group of welding processes which
produces coalescence of materials by heating them to a suitable temperature and
by using a filler metal, having a liquidus above 840 °F (450 °C) and below the
solidus of the base materials. The filler metal is distributed between the
closely fitted surfaces of the joint by capillary attraction.
Burr – A rough ridge, edge, protuberance, or
area left on metal after cutting, drilling, punching, or stamping.
Buttering – A form of surfacing in which one
or more layers of weld metal are deposited (for example, a high alloy weld
deposit on steel base metal which is to be welded to a dissimilar base metal).
The buttering provides a suitable transition weld deposit for subsequent
completion of the butt weld on the groove face of one member.
Butt Joint – A joint between two members lying
in the same plane.
Busted Out - failing a weld test because of
defects in the welds. "He busted out on his test plates and didn't get
hired."
