API 577 Welding Inspection and Metallurgy Course Scope
This recommended practice (RP) provides guidance to the API authorized inspector on welding inspection as encountered with fabrication and repair of refinery and chemical plant equipment and piping.
This RP includes descriptions of common welding processes, welding procedures, welder qualifications, metallurgical effects from welding, and inspection techniques to aid the inspector in fulfilling their role implementing API 510, API 570, API 653 and API 582.
API 577 Welding Inspection and Metallurgy Course covers the level of learning and training obtained from this document is not a replacement for the training and experience required to be a certified welding inspector under one of the established welding certification programs such as the American Welding Society (AWS) Certified Welding Inspector (CWI), or Canadian and European equivalent schemes such as CWB, CSWIP, PCN, or EFW.
API 577 Welding Inspection and Metallurgy Course covers this RP does not require all welds to be inspected; nor does it require welds to be inspected to specific techniques and extent.
API 577 Welding Inspection and Metallurgy Course Welds selected for inspection, and the appropriate inspection techniques, should be determined by the welding inspectors, engineers, or other responsible personnel using the applicable code or standard.
The importance, difficulty, and problems that could be encountered during welding should be considered by all involved. API 577 Welding Inspection and Metallurgy Course covers A welding engineer should be consulted on any critical, specialized or complex welding issues.
Terms, Definitions, and Acronyms
API 577 Welding Inspection and Metallurgy Course covers For the purposes of this document, the following definitions apply.
ACFM
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
The shortest distance between the weld root and the face of a fillet weld.
air carbon arc cutting
CAC - A
A carbon arc cutting process variation that removes molten metal with a jet of air.
arc blow
The deflection of an arc from its normal path because of magnetic forces.
arc length
The distance from the tip of the welding electrode to the adjacent surface of the weld pool.
arc strike
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
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
A fusion weld made without filler metal.
back-gouging
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
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
The metal to be welded, often called parent metal.
bavel angle
The angle between the bevel of a joint member and a plane perpendicular to the surface of the member.
burn-through
A term for excessive visible root reinforcement in a joint welded from one side or a hole through the root bead.
buttering
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
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
An arc welding power source with a volt-ampere relationship yielding a large welding current change from a small voltage change.
corrosion specialist
A person, acceptable to the owner/user, who has knowledge and experience in corrosion damage mechanisms, metallurgy, materials selection, and corrosion monitoring techniques.
