Greetings to all subscribers and visitors to the channel. If you decide to develop a manual arc welding by yourself, then you went to the correct channel!
Who regularly read my article, he probably noticed that I used to experiment and come up with all sorts of creative solutions when working with metal.
Today's article is exactly about this experimental method was the logical solution is found as programs and without complex calculations mark and zapilivaem grinder round pipes for docking under any angles.
Take two pieces of pipe 43 and try to match them to any arbitrary angle, such as for example here in the photo.
Note the marker along pipes straight lines, so that we could see the borders of our desired angle.
Grasp welding inner pair of pipe ends and make temporary splicing of any available metal-I piece Area taken to design turned rigid.
We measure the distance between the line of external pipe ends in this design, it is very important to measure accurately.
Then mark the mid-height diameter of the two pipes.
So he is our simple tool to mark, I made it out of the electrode. Cleared of wash and cut exactly to size the distance between the outer ends of the pipes, which we measured with a ruler.
Take this piece of the electrode and a little pressed for pipes begin to roll from both midpoints up, noting in passing Place marker points through which this piece is rolled electrode, overturn our design, and we do everything also. If you see that the electrode leaves aside, go back to the mark and carefully keep counting.
If done properly and carefully, it should get here this markup.
Now, this marked-construction ship to cutting grinder.
Sawing grinder exactly markup, cut the tack-welded corner, the desired gash ready.
We spread our and butted tubes within the boundaries of the corner, originally labeled marker. washed down angle turned out pretty accurate, there is little difference in the gaps, but it is insignificant.
Here's a simple method can be applied without the need for programs from the Internet and complex calculations.
