I need to connect bow copper as on the picture with a copper pipe, and I'd like to avoid soldering. Is there a special tool for this?

2It's not really clear what you're hoping to hear ... Those fittings are intended to be soldered and the 'special tool' is either a torch or large soldering iron. – brhans Jul 2 '18 at 23:23

Sorry if I wasn't clear enough. I've thought there might be some sort of clamp tool, instead of soldering, which could be dangerous for beginner in the first place. – Mark Jul 2 '18 at 23:27

There are solderless methods of connecting copper (ex. sharkbite). This kind of question is moving a little into the product recommendation world, however... – Hari Ganti Jul 2 '18 at 23:55

1Soldering is easy, even for a beginner. YouTube. – paul Jul 3 '18 at 13:47

1You avoid soldering by using press-on connectors (Sharkbite) to adapt to pex tubing (crimp connectors). You don't screw around with copper. Like Paul said, sweating joints is easy and is no more dangerous than operating a birthday cake. – isherwood Jul 3 '18 at 14:09
There is a system for connecting copper tubing and copper fittings that does not use solder. Just google "Propress" for an example. Some places rent the tool or you can purchase one. Before I retired the company I worked for used this tool for a lot of copper fittings from 1/2" thru 4". It works very well, is quick and does a lasting job.
To avoid soldering I would use either a compression elbow or a push-fit elbow. But it depends on what the pipe is carrying (water or gas).
Useful tools include pipe-cutters and appropriate sized spanners/wrenches.

Depending on what you're planning on using the pipes for, you could use an epoxy that was designed for metal to metal bonds.
I wouldn't use epoxy for a constant pressure in-wall application, but I did use it to extend a short nipple for a tub spout on an acrylic tub. I wrapped it in a heating pad to post cure for extra insurance.
