When performing welding, you need to achieve reliability, accuracy and neatness of the connection. Let's consider 5 ideas, using which you can achieve the highest quality results.
Welding pipes of different diameters at right angles
If you need to weld a thin one at a right angle to the end of a thick pipe, you should mark the junction of the smaller one with a marker on the larger one.
Then a figured cut is made on it according to the markings.
The resulting horns are cut lengthwise into several segments.
After such preparation, a thin pipe is inserted, and the segments are bent with hammer blows, compressing it.
Next, they are welded, as is the joint between the pipes.
The result is a very reliable and neat connection. This method can be used when welding outdoor horizontal bars, beams, etc.
Bending a U-shaped profile or channel
If it is necessary to bend a U-shaped profile, you need to cut its side at the bending point, then make 2 more of the same cuts with a step equal to its width.
Next, the profile is turned upside down, and its central section is extended to the second sidewall. After this, you need to cut a diagonal, as in the photo, and bend it.Using this method, you can bend both a small channel and a galvanized profile for installing drywall.
Connecting parts with electric rivets
When welding various parts, especially thin-walled ones, so that the metal does not lead, instead of a continuous seam, you can do spot welding. To do this, at least 2 through holes are drilled in one of the parts.
The prepared part is placed in place and welded with an electrode through the holes. The result is some semblance of rivets. Such a connection practically eliminates the possibility that the part will move during welding, and it is also quite reliable.
Homemade fry
To accurately transfer the angles from one structure to the workpieces being welded, a special malka tool is used. Usually such a device is extremely flimsy, so it is better to make it yourself than to buy it. To do this, take 2 identical pieces of steel strip and a small insert from the same, but cut on one side at an angle.
The insert is placed between two blanks and they are welded together. Next, a ruler is made from the strip with a longitudinal cut in the middle. It is screwed with a bolt and a wing nut to the previous part through the hole.
To use the pulley, you need to loosen the nut, set the sides to the desired angle, resting against it, and then tighten it back. The tool is then used as a template.
Reliable connection between strip and pipe at right angles
To weld a strip to a pipe, you must first cut a groove of the appropriate length and width in it with a grinder.
Then a strip is inserted into it and scalded. With this connection, it will no longer vomit under load.
