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.
Today you will learn one important trick when working with grinder. How to hold a grinder to cut always straight.
Consider the example of the method of cutting shaped tube, since this material is the most demanded today in our everyday welding work. The pipe size of 60 by 30, thickness 2 mm.
Proizvedom cut at 90 degrees, but we will not cut all 4 sides of the markup, and mark only one side, and took one cut smoothly. And how do we keep the grinder to make it one rezom, and besides, exactly? Now I tell.
I've been wanting to find a solution as a grinder at a cut sawing off smoothly, I had to think, to experiment, but a solution was found.
Take plane exposed at the horizon, in this example, our profiled tube, put on it a disc grinder, and presses it to gon, which is also on the profiled pipe.
And at this moment we are looking relative position of the housing and nut grinder, which presses the disc. Here is the relative position of the housing and the nuts will be for us to fit an eye, at this moment the Bulgarian and the disc will be strictly perpendicular to the surface of the shaped tube.
See you need in this polozhenii- look on top of the grinder housing, it should be as it were the center of sight, and therefore the relative position of the housing and nuts, we will only see with one eye. No need to look to the side, hold the opinion strictly on the center housing.
Then, on the nut needed to make a mark bright color of the place, a pencil, a marker that you have available. When the disc is spinning, this colored mark will be clearly visible, there will be only gently to combine housing and the edge of the mark.
Let us now sawed off. For complete visibility and verification of their way to make three marks on the pipe side 30 mm, then we have to cut off a thin three flat part of the tube.
Sawing. Began to saw, for the first time look at how the disk is on the line, but when the disc is already begins dug into the metal, then there begin to look at your customized sight-relative position of the housing and the nut.
And another important point to make linings for the cut material so that the material was in a horizontal plane, put on a level. Then it will work, it is not difficult, and is not long, but, exactly one rezom sawing, you do this job 5 times faster than the mark and cut all four sides of the profile pipe.
As we can see, the cuts are obtained perfectly flat. The technology works on all 100!
But it is better to see once than to hear many times, let's see a video where all this technology straight cut is shown in detail.
