Greetings to all who are interested in the theme of welding, and who decided to develop its own. Today will tell a real example and a variety of pictures such right information How to cut the workpiece, to collect on tack, and from the corner of the frame scald .
Boil frame we will of 40 brackets, 4 mm thick. The dimensions of our future structures will be 600 mm by 760 mm. The first step is cut off from the whole whip the needed billets with these dimensions.
Then you have all the ends of the blanks 4 gash angle of 45 degrees, because such connection will be much stronger and much better looking.
After desperately angle at 45 degrees, we take and remove any burrs that we would interfere in the assembly of future construction.
Then there are 2 variants of the assembly, if you have a welding table with conductor for display blanks at 90 degrees, then we expose it and rigidly fix the clamps in the assembled position tack.
But most of these tables there, and so we're just going on any flat plane (the plane of the assembly without even impossible, otherwise the design is not out), if you need a pair of trestles or bars proftrubu, it is important to expose the horizon, and they also throw across a couple of boards, bars, etc. proftrub. And here on this flat surface and will assemble.
On a flat surface, we expose the workpiece 2 at an angle of slightly more than 90 degrees and will do in this position tack on the inner side of coupling these two parts. Why do we do that? If you just put up 90 degrees and put a tack, it drags a little nook and corner will be less than 90 degrees, and then bring the right angle is not easy.
So, we did tack, it is a little cool, and is now on a square adjusting the workpiece by 90 degrees, so it is very simple. A second pair of corners we have to grab the same way. Now grab between these two pairs of parts, also making a tack on the inner side of the interface so over-stuck design will be like the hinges, and it will be very easy to put diagonal.
Diagonal is set so meriim tape measure the distance between the diagonal corners, and if there is a difference in size, we find that the difference, divide by 2, and add this number to a smaller or subtract from the larger, so we get the size you need us diagonal.
So for example, a diagonal of 100 mm and one 110 mm, they have a difference of 10 mm, divide by 2, we obtain 5 mm. These 5 mm is added to the diagonal size of 100 mm and obtain the required size, which is equal to 105 mm, I hope it is clear, who did not yet know.
Calculating the correct diagonal us, we take a hammer and gently knock on the corner of the long diagonal, adjusting it to the desired size, which we calculated.
Now we put another tack uzhena outer corners, putting them now diagonally design, again with a tape measure We control the size of the diagonal, and now becoming the latest tack at the bottom of the inner corner, making it well diagonally.
Welding is done in the same sequence as the set tack-internal vertical seam, then external, internal in the lowermost position, overturn frame and cook other seams in the bottom position.
Most importantly, do not forget to do seams strictly diagonally, so much reduces the likelihood of diversion of the diagonals and the curvature of the structure.
We clean the seams and make control measurement with a tape measure, if all originally done correctly and sequentially, with a diagonal will be all right, I have in this example, it is as it was, and I remained in the difference of 1 mm.
Here's a simple set of steps to weld a flat box from the corner.
