Greetings to my subscribers and channel guests. Our blog was created for self-taught beginners in manual arc welding, here we share practical tips on welding and locksmith preparatory work before welding, where a grinder and other tool.
Someday any person who has decided to master welding and grinder will have to deal with round pipes. Weld them, join them, make tie-ins. Therefore, today I will show you 2 ways to cut a pipe into a pipe at 90 degrees of the same diameter. These are simple garage methods that require a minimum of calculations. Knowledge is power, and ignorance takes so much power until you catch up with how to do it!
To make a pipe cut into the pipe, you need to make a grinder at the end of the pipe.
These cuts will have this shape. In this case, the pipes will be connected in a T-shape without having large gaps, which means that it will be much easier and faster to weld this connection. Let's start the markup.
First, we need to split the end of the pipe into 4 even parts. Some experienced welders and locksmiths do this by eye, but we will mark more accurately so that later we do not weld large gaps.
On a sheet of paper, or on any surface, draw two lines intersected at right angles. The intersection point will be considered zero. We set aside 30 mm from zero in all directions, this is the size of the pipe radius, the diameter of our pipes is 60 mm.
We put the end of the pipe within the boundaries of our marked radii and put 4 marks on the pipe itself, this is how we exactly split the end into 4 even parts.
Now we put off at two opposite marks a size equal to a third of the pipe diameter - we get 20 mm. Now it remains to smoothly, and not in a straight line, connect these marks to get the shapes in the shape of a semicircle. This can be done by hand if the pipe diameter is small.
Or you can take a flexible plastic thing, for example, such a disposable clamp.
And on such a clamp we mark a smooth semicircle.
This is the markup we should get. Now we take a grinder and carefully make these 2 semicircular cutouts.
Such a clear pairing of pipes should be obtained if everything is done exactly as described.
Friends, there is another simple garage way of marking, but let's see it in a detailed video, where I show all the subtleties of this process.
