Soldering fixings to the side of pipes without t's

[Hadlowj]

Can anyone tell me what the name is for the process of soldering fittings to the wall of a pipe is like in the pic below? I remember seeing a video of someone making the holes for the fitting but can’t find it anymore and need to make a fitting like in the picture.
Many thanks

Brazing

In the video there was some tool that punched the hole and pulled a lip for the fitting, any idea on what the tool is called please?

Note they make them for uk tube / metric as well

 

[S.P.S.]

I don’t think I like the look of that! Doesn’t have a lot of mating surface area!

The tool is called a 'Branch Puller'.
There's a mechanical one called 'T-Drill'
Check that out - I used one for 15 years.
Almost redundant now due to press fittings, but still use it on occasions.

Do you braze the pipes together or solder? What kind of pressure are these joints rated to?

It doesn't need as much if it's brazed.

Obviously brazed would be stronger but it says it can be soldered so was just curious as to the strength

I thought that. Personally I wouldn't trust that short joint with solder.
