Friends, all welcome on our channel, dedicated to all those who have mastered their own welding, or thinks about it. Here we try to give real information based on many years of welding practice, you will not find in the welding textbooks.
I think many beginners who have decided to learn welding, will be an important topic How to cut circular tube at 45 degrees to connect at 90 .
If you read on the internet, how to do it, there will be offered to download special software, and then print out paper patterns ready. Or independently raschertit here such patterns as the top of the photo, they are called fish pattern. But, in my opinion, is long and dreary, look what I came up with a simple way to solve this problem.
We will need here are wooden sticks, they are called skewers for kebabs sold in hardware stores, are inexpensive. More will need a coil of tape, that's all.
A piece of pipe wrapped sticks, and gave their gums. The pipe is 42 mm in outer diameter.
We catch a piece of pipe to any plane, but we catch so that the distance from the upper end of the pipe to this plane constituted our pipe diameter, in this case 42 mm. Roughly put on line a distance, did tack, and then brought it to the exact values of the distance (42 mm).
Now drop the skewers all around the circle until they touch the plane, and when they are all on the plane, we are in this position with tape wrapped with them in a few laps.
Tack torn off from the plane, that is the pattern we have.
Move our wooden mold through the pipe to the desired mark us, I did not put a mark, he moved freely. Then take your layout tools, and draw out the shape of shpazhek.
Remove the mold from the pipe, take grinders and carefully sawing on the marked location.
That's it, we have turned the pipe joint at 90 degrees, the joint accuracy is quite good, you can scald.
Friends, let's see the video with this process, because the fullness I could not pass the information in the article would otherwise have to read for a long time!
