Do not know the term, Weldolet, but if your question is where or how do you decide where you are going to cut a pipe to add a branch line, then it is a matter of where it is possibe and the easiest to do. It is not always as close to where you would like it, but where it makes the most sense to do it. Depends on the type of pipe involved also. Copper or PVC you can cut any place you want. Steel, you can replace a coupling with a T and a union if it is in the middle of a run. With steel either black or galvanized you will have to add a union or go back to the end of the run and take everything apart.
Weld-o-lets are sized for the diameter of the pipe you are tying into and the diameter of the pipe you are adding. Example: 2" x 3" or 6" x 10". If you need the branch pipe to have a theaded connection you would select a Thread-o-let instead. Sizing is the same. Some o-let's can be used for a range of piping sizes. Example: a 3/4" thread-o-let may have 8-12 marked on it meaning you can weld it on to either 8", 10" or 12" pipe.
Weldolet and Sockolet are basically self reinforced fittings. Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service. Sockolet is used for socket welding branch connection, which require reinforcing pad.
A male and female thread connection if metal pipe. If poly pipe a welded fusion connection.
half coupling used to take branch from header ie: 2" header to 3/4' branch. where full coupling used to connect to straight pipe. ie: 2" to 2" pipe connection.

In programming a "pipe" usually refers to a connection to a data source (aka a database). The difference between a queue and a pipe is that a queue usually caches some data from the data source while a pipe is just a connection to the data source.
A weldolet is a fitting you weld on a (run) pipe, and then butt weld a branch pipe to it. A tredolet is a fitting you weld on a (run) pipe, and then screw a threaded branch pipe to it. Some people call this a threadolet A sockolet is a fitting you weld on a (run) pipe, and then socket weld a branch pipe to it. A nipolet is the same as a weldolet or thredolet but has an elongated branch connection. You have to specify if it's a welded or threaded nipolet.
Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service.
A Weldolet is a butt-weld branch connection. It is designed to provide integral reinforcement and minimize stress. They are made to match or exceed the schedule of the pipe.

Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service.

Weldolet has a Bevelled end to butt weld the pipe whereas in sockolet the pipe/tube goes inside it and there it is fillet welded.

A pipe is a long tube in the ground that connects the magma chamber to the earths surface.

male iron pipe--relates to a threaded connection--one form of pipe connection
There are size on size weldolets. The hold on the run pipe will necessarily be undersize (either hot tap or torch ) because it's not possible to cut the same size hole in the run without damaging the base material.
