2. List of welding codes - Wikipedia

   en.wikipedia.org/wiki/List_of_welding_codes

   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 BS 4515-1: Specification for welding of steel pipelines on land and offshore - Part 1 ...

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. Symbols and conventions used in welding documentation

   en.wikipedia.org/wiki/Symbols_and_conventions...

   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.

5. Rotary friction welding - Wikipedia

   en.wikipedia.org/wiki/Rotary_friction_welding

   The results are for example not the same in welds made for the European Space Agency with a high turnover ω = 14000 rpm [61] or another example from Warsaw technical university 12000 rpm [41] and no typical very short friction time only 60 milliseconds [42] instead of using an standard parameters, in addition, in this case, ultra fine grain ...

6. A36 steel - Wikipedia

   en.wikipedia.org/wiki/A36_steel

   A36 is readily welded by all welding processes. As a result, the most common welding methods for A36 are the cheapest and easiest: shielded metal arc welding (SMAW, or stick welding), gas metal arc welding (GMAW, or MIG welding), and oxyacetylene welding. A36 steel is also commonly bolted and riveted in structural applications. High-strength ...

7. 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.
