Greetings to all subscribers and visitors to the channel. If you decided to learn a manual arc welding by yourself, then you get to the desired channel, where you can find hundreds of tips and tricks that will help further work with metal.
Today will analyze a specific topic, like welded in (make the sidebar) tube into the pipe at any angle.
To take an illustrative example, two small pieces of pipes with outer dimensions of 84 and 88 mm, and will try welded in one tube to another under arbitrarily selected angle. For the convenience of the markup, I picked up the pipe.
For markup we need a corner piece, but need a small area, with small shelves for a more accurate and correct markup. This corner I cut proftruby from 15 to 15.
Next, take the line and measure the maximum distance from the tube end is welded to a contact point with the surface of another tube. And then transfer this amount to our area, making the white marker tags.
Now putting a corner along the welded tube and the other tube is omitted, and after the end of the shelf bracket touches the pipe, then put point is welded to the tube at the level of the markup of the corner, and so doing, going in one direction and then the other side is welded around the circumference pipe.
Now connect the point marking the pipe in a straight line, and cut it no longer needs a small segment of the grinder.
That's because the tube is welded to the main village of the pipe after all of our manipulation. The accuracy of this method of fitting is pretty good, only when the same diameter of the pipe, there are several places, where you may cook in several passes, or can be a bit shlifanut grinder for a perfect abutment surfaces of these pipes.
Marker I noted the places where you can walk with sanding disc grinder, if you need a perfect fit for this tie.
But if the diameter of the welded tube is smaller than the main, the pipe landing place, scribed by the method will be fairly accurate and dense.
That's the easiest way you can do markup, which uses computer programs, to make a scoring template, I came to this method, as always, the experimental logic by!
