4. Weldability - Wikipedia

   en.wikipedia.org/wiki/Weldability

   High-strength low-alloy steels (HSLA) were developed especially for welding applications during the 1970s, and these generally easy to weld materials have good strength, making them ideal for many welding applications. [5] Stainless steels, because of their high chromium content, tend to behave differently with respect to weldability than other ...

5. Welder certification - Wikipedia

   en.wikipedia.org/wiki/Welder_certification

   The ASME code is typically used for pressure vessel and pressure piping applications, and CSA Standards are used for structural, general manufacturing and non-pressure applications. There are 3 major CSA Standards to which welders may be qualified: CSA W47.1 [ 4 ] for steels (including stainless steels), CSA W47.2 [ 5 ] for aluminum, and CSA ...

6. Friction welding - Wikipedia

   en.wikipedia.org/wiki/Friction_welding

   An improved modification of the standard friction welding technique is low force friction welding, a hybrid technology developed by EWI and MTI, which "uses an external energy source to raise the interface temperature of the two parts being joined, thereby reducing the process forces required to make a solid-state weld compared to traditional ...

7. Welding Procedure Specification - Wikipedia

   en.wikipedia.org/wiki/Welding_Procedure...

   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.
