Weld Quality
Intro To Metals Weld Quality 2019-2020
| Term | Definition |
|---|---|
| Arc Blow | The deflection of an arc from its intended path by magnetic forces |
| Brazing | A method of joining metal using heat and a filler metal with a melting point above 842°F (450°C). Unlike welding, the base metal is not melted during the brazing process |
| Code | A document that establishes the minimum requirements for a product or process. Codes can be, and often are, adopted as laws |
| Defect | A discontinuity or imperfection that renders a part of the product or the entire product unable to meet minimum acceptable standards or specifications |
| Discontinuity | A change or break in the shop or structure of a part that may or may not be considered a defect, depending on the code |
| Embrittled | Metal that has been made brittle and that will tend to crack with little bending. |
| Essential Variable | Items in a welding procedure specification (WPS) that cannot be changed without requalifying the WPS |
| Hardenable Materials | Metals that have the ability to be made harder by heating and then cooling |
| Homogeneity | The quality or state of having a uniform structure or composition throughout. |
| Inclusion | Foreign matter introduced into and remaining in a weld |
| Laminations | Cracks in the base meta formed when layers separate |
| Non-essential Variable | Items in a welding procedure specification (WPS) that can be changed without requalifying the WPS |
| Notch Toughness | The ability of a material to absorb energy in the presence of a flaw such as a notch |
| Procedure Qualification Record | The document containing the results of the nondestructive and destructive testing required to qualify a WPS |
| Radiographic | Describes images made by passing X-rays or gamma rays through an object and recording the variations in density on photographic film |
| Specification | A document that defines in detail the work to be performed or the materials to be used in a product or process |
| Standard | A document that defines how a code is to be implemented |
| Transducer | A device that converts one form of energy to another |
| Underbead Cracking | Cracking in the base metal near the weld, but under the surface |
| Welding Procedure Qualification | The demonstration that welds made following a specific process can meet prescribed standards |
| Supplemental Essential Variable | The variables that must be considered when notch toughness requirements are involved |
