Friends all welcome. Today will be another useful topic for anyone who has decided to develop a manual arc welding alone. And the article itself will be on how to weld grinder and straighten the curve round tube.

I dragged a few of the ferrous metal pipe and asked of them to make a tube of a certain length, ie ottortsevat short and match them. Among them was a pretty curve of the tube, of course the first thing we'll work with it, namely straighten it for future connections.

Is applied to the curve of the circular pipe-line square, you can make any line item. We need to see the place where the pipe is only beginning to be bent, in this place becoming the first line.

Then turn straight square tube to the other side and define the place where the curvature of the circular pipe itself will as far as possible from the line at this point draw a couple more labels.

Now take grinders and these labels do badly by the hump curve pipe to a depth of slightly more than half of the pipe, thus tried to gouge depth was the same. Desperately just the thickness of the cut-off wheel. I sawed around 230 2mm.

After these gashes we can easily give a round tube in direct state, simply by bending it in the direction of our gashes. Now make gashes on potholders and fully brew our gashes, but there is one nuance welding metal pulls strongly, and therefore rectifying tube completely in a straight line is not necessary, it is necessary to leave a small curvature, because after welding this curvature will pull together and disappear. Well, if you stay in one or the other side of the small curvature of something you can just rihtanut chilled tube, knocking on another piece of iron is hump curvature.

The same thing we do with the other side of the pipe-mark up lines, zapilivaem grinder, straight, and then welded.
