What is a Socket Weld?

 · Socket weld fittings are used for connecting pipes. A pipe is inserted into the recessed part of the flange, valve or fitting. Fillet type seal welds are applied to join fittings with pipes. Socket weld fittings are an excellent choice for a wide range of applications since they have high leakage integrity and high structural strength.

Difference Between Socket Weld and Butt Weld

 · Socket weld is troublesome in corrosive fluid service due to crevice corrosion. And it is easy to corrode due to the discontinuity of the smooth pipe internals. Butt weld is the "best" in terms of strength, fatigue, and corrosion resistance, and temperatures compliance. However, it is more difficult to fit-up and weld properly, needing ...

rt socket welds

 · The first run of socket welds will be RT''d (elliptical shots) to verify the fitters have used proper spacing or inserted the Gap-O-Lets. Project I was on a couple of years back "shot" 200 sockets right off the bat (fired one fitter) and to my knowledge never shot any more after that. This is what I call compliance through intimmidation.

Fillet Welded Joints

Fillet welded joints are not only the most frequently used weld joints but are also one of the most difficult to weld with any real degree of consistency. Fillet welds require a higher heat input than a butt joint of the same thickness and, with less skilled welders this can lead to lack of penetration and/or fusion defects that cannot be detected by visual examination and other NDT techniques.

Socket Weld Fittings General

A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange.
