Friends all welcome. Will continue today, a multi-faceted topic of welding and cutting of profile pipes. As has been repeatedly mentioned in our previous articles-shaped tubes is the most abundant material for welding designs for our domestic needs in the area, the garage, in the country and so on.
Here's a look at the photos of their swing, I cooked the children a few years ago. The design of large lateral triangles of the profile tube has a sharp angle at the apex. Sectional tubes for such docking zapilivaem had a certain way and how to do it simply and without complex calculations, I'll continue.
For example, take two pieces of size 40 by 20 and proftruby white marker arbitrarily drawn corner form which must repeat these tubes 2 and washed down after docking. Let the line traced the angle of the external borders will be stacked pipes.
We take our pieces of shaped pipes and spread along the lines traced in the corner. But lay out so that the vertices of one of the pipes lay on top of the angle traced marker and the vertex of the second pipe is compatible (impose on it) with a first vertex on the photo-all detail and shown graphically.
Then just simply note marker on both tubes point of the point of intersection opposite the top. Overturn proftruby points to himself and draw a straight line across the pipe, then I think it is clear that we draw the line on the inner sides of the angle of the future.
Again overturn pipe take any marker and a ruler, connect lines and vertices pipe already drawn transverse line. That's all the correct markings done is to take a grinder and gently cut the unnecessary parts marked with a marker.
Grinder cut, lay pipes traced back to the border marker angle. We see that everything turned out as we planned.
This method is very simple, and who did not know about it can now easily be used for their own purposes.
