The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
Welding terms and symbols. Glossary for welding, brazing and thermal cutting BS 499-2C: Welding terms and symbols. European arc welding symbols in chart form BS 2633: Specification for Class I arc welding of ferritic steel pipework for carrying fluids BS 2971: Specification for class II arc welding of carbon steel pipework for carrying fluids ...
An abbreviation used in parts lists (PLs, LMs, BoMs) in the quantity-per-assembly field when a discrete count is not applicable. For example, in an assembly with a bolted joint using four bolts, the PL quantity column will say "4" for the bolt PN, "4" for the nut PN, and "AR" for the liquid threadlocker that will be applied.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
MDT – modular formation dynamic tester, a tool used to get formation pressure in the hole (not borehole pressure which the PWD does). MDT could be run on Wireline or on the Drill Pipe; MDR – mud damage removal (acid bullheading) MEA – monoethanolamine; MEG – monoethylene glycol; MEIC – Mechanical Electrical Instrumentation Commission

These diagrams are used to represent which types of phase changes will occur in a material as it is cooled at different rates. These diagrams are often more useful than time-temperature-transformation diagrams because it is more convenient to cool materials at a certain rate (temperature-variable cooling), than to cool quickly and hold at a ...
