Friends all welcome. We continue to talk various useful pieces for anyone who decided to learn welding alone. And today there is such a useful topic as your own hands to make a penny device to weld the pipe into the pipe at any angle.
For example, take two round tubes, one of which outer diameter is 76mm, 48mm and the second and try welded in a lower large diameter at an arbitrary angle. To do this, the greater the pipe grab corner it will have a guide for our at the pipe.
And to a lesser pipe we make the necessary grinder desperately need the correct markup for which you want to cut to the pipe firmly sat on the surface of another tube.
For this we need only a set of wooden shpazhek for barbecue, a pair of triple gums and skein tape. Everything is sold at any hardware store and the whole set will cost no more than 70 rubles.
We know that the outer diameter of our smaller tube is 48mm, we need to know its circumference, this 48 multiply by 3.14 and get the number of the order of 150mm. Now we nuzhnovylozhit the skewers in a single layer on a length of 150mm.
Now these skewers wrap tube 48 tightly in one layer and fix all the two bands.
Arrange shpazhek ends flush with the end of our 48 tubes. To this tube set on any flat surface and omit skewers all around it.
Now we put our pipe 48 wrapped skewers into the guide area and begin to push skewers circularly until until each touches the surface 76 of the tube. By the way this operation is convenient to do the same skewer, pushing it into the ends of these thin pieces of wood.
When all the pieces of wood to touch the pipe in a circle, we take the tape and fix this situation shpazhek. Then we put forward our 48 flush pipe to the farthest ends of pieces of wood, and in that position we put marking, going with a pencil or other layout tools along the end of our recorded tape pieces of wood.
Remove from the pipe our wooden mold and grinder on a marking cut the unnecessary part. Here's a result we get after all these simple steps.
