   en.wikipedia.org/wiki/List_of_welding_codes

   Electron beam welding, six parts ISO 15607: Specification and qualification of welding procedures for metallic materials - General rules ISO/TR 15608: Welding - Guidelines for a metallic material grouping system ISO 15609: Specification and qualification of welding procedures for metallic materials - Welding procedure specification, five parts ...

3. Welding Procedure Specification - Wikipedia

   en.wikipedia.org/.../Welding_Procedure_Specification

   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.

4. Threaded rod - Wikipedia

   en.wikipedia.org/wiki/Threaded_rod

   A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. [1] They are designed to be used in tension. [2] Threaded rod in bar stock form is often called all-thread (ATR); other names include fully-threaded rod, redi-rod, continuously-threaded rod ...

5. Filler metal - Wikipedia

   en.wikipedia.org/wiki/Filler_metal

   Many gas welding processes, such as lead burning, are typically autogenous and a separate wire filler rod of the same metal is only added if there is a gap to fill. Some metals, such as lead or Birmabright aluminium alloy, use offcut strips of the same metal as filler.

6. Rod end bearing - Wikipedia

   en.wikipedia.org/wiki/Rod_end_bearing

   A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links , tie rods , or anywhere a precision articulating joint is required, and where a clevis end (which requires perfect 90-degree alignment between the ...

7. Trapezoidal thread form - Wikipedia

   en.wikipedia.org/wiki/Trapezoidal_thread_form

   Basic Acme thread profile. The Acme thread form has a 29° thread angle with a thread height half of the pitch; the apex (or crest) and valley (or root) are flat.This shape is easier to machine (faster cutting, longer tool life) than a square thread.

8. United States Military Standard - Wikipedia

   en.wikipedia.org/wiki/United_States_Military...

   Detail Specification A specification that states design requirements, such as materials to be used, how a requirement is to be achieved, or how an item is to be fabricated or constructed. A specification that contains both performance and detail requirements is still considered a detail specification.

9. Gas metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_metal_arc_welding

   Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
