Complete Solutions19
ACFM - ANSWERS-The alternating current field measurement (ACFM) method is an
electromagnetic inspection technique which can be
used to detect and size surface breaking (or in some cases near surface) defects in both
magnetic and non-magnetic
materials.
actual throat - ANSWERS-The shortest distance between the weld root and the face of a fillet
weld.
air carbon arc cutting
CAC-A - ANSWERS-A carbon arc cutting process variation that removes molten metal with a jet
of air.
arc blow - ANSWERS-The deflection of an arc from its normal path because of magnetic forces.
arc length - ANSWERS-The distance from the tip of the welding electrode to the adjacent
surface of the weld pool.
arc strike - ANSWERS-A discontinuity resulting from an arc, consisting of any localized remelted
metal, heat-affected metal, or change in the
,surface profile of any metal object.
arc welding
AW - ANSWERS-A group of welding processes that produces coalescence of work pieces by
heating them with an arc. The processes
are used with or without the application of pressure and with or without filler metal.
autogenous weld - ANSWERS-A fusion weld made without filler metal.
back-gouging - ANSWERS-The removal of weld metal and base metal from the weld root side of
a welded joint to facilitate complete fusion and
complete joint penetration upon subsequent welding from that side.
backing - ANSWERS-A material or device placed against the back-side of the joint, or at both
sides of a weld in welding, to support and
retain molten weld metal.
base metal - ANSWERS-The metal to be welded, often called parent metal.
bevel angle - ANSWERS-The angle between the bevel of a joint member and a plane
perpendicular to the surface of the member.
burn-through - ANSWERS-A term for excessive visible root reinforcement in a joint welded from
one side or a hole through the root bead.
, buttering - ANSWERS-One or more layers of deposited weld metal on the face of a weld
preparation or surface that will be part of a welded
joint.
constant current power supply
cc - ANSWERS-An arc welding power source with a volt-ampere relationship yielding a small
welding current change from a large arc
voltage change.
constant voltage power supply
cv - ANSWERS-An arc welding power source with a volt-ampere relationship yielding a large
welding current change from a small
voltage change.
corrosion specialist - ANSWERS-A person, acceptable to the owner/user, who has knowledge
and experience in corrosion damage mechanisms,
metallurgy, materials selection, and corrosion monitoring techniques.
crack - ANSWERS-A fracture type discontinuity characterized by a sharp tip and high ratio of
length and width to opening displacement.
