2 in 1. Magnetic mass and do-it-yourself corner

Hello dear readers and the inhabitants of our site!
This article will be interesting to everyone involved in welding. In it AndRey00001, the user of the Yaplakal site, will tell you how to make an interesting magnetic mass, which will simultaneously serve as a corner.

Materials
- Steel sheet 0.6 mm.
- A few neodymium magnets.
- A pair of scraps of wire
- Insulation tape
- Bolt, nut, washer.

Instruments, used by the author.
- Screwdriver or drill machine
- Welding machine
- Pliers, wrenches
- Vise.

Manufacturing process.
First, Andrei cut a triangle out of a steel sheet. And, holding it in a vice, he welded a piece of hairpin to its center. You can also use a bolt, welding it with a hat - there will be a larger contact area.



It turned out here is such a first detail.


For the second part of the corner, the author bent such a triangle from the sheet. Using a drilling machine he made a hole for the stud.



Now you need to install several neodymium magnets in the corners of the case, and just close it.





The edges of the body are not welded, but clamped with the help of such a trimmed washer.




Andrey puts on the mass terminal of the welding machine and clamps it with a self-locking nut using a wrench.




For greater rigidity of the connection, it applies a pair of wire scraps, and insulates the terminal by wrapping it with electrical tape. Then puts on a rubber cambric.





Everything is perfectly magnetized.


The time for testing has come. Andrey turns on the inverter and checks the quality of the contact. The arc lights up on the first try. Tries to connect two unnecessary pieces of iron. The contact is just great.






Now welds a piece of pipe to the steel profile at 90 degrees. Everything is fine, even in the corner you can see.




And if the "crocodile" of the welding machine has nowhere to connect? It is enough to magnetize the mass onto the stripped section of the metal structure!


Thanks to Andrey for an interesting idea for the next version of the magnetic corner

For example: the maximum operating temperature for the use of neodymium magnets ranges from +80 to +220 ° C, depending on the brand of magnetic material.

Curie temperature - the temperature at which the magnet is fully demagnetized.

For example: the NdFeB magnet has a Curie temperature within +300 / +380 ° С.
Ordinary mass does not die irrevocably due to poor contact, or a small area of ​​contact !!! Why is it impossible to rust it, or paint? ... (Sorry, but you can see right away that "not a welder."))). So, I’ll explain: if the mass is bad - it is caked with a “crocodile”, scratched. I tried again ... Sometimes it “rattled”, drove it down - and the mass appeared (And the magnetic from this is already ejected!). I also scratched the paint and cook it. The mass is warming - well, to hell with it!))) (And the magnetic one is also ejected!) ... Ask the welders, did they have such that the mass was heating up? What mass sparked? What is it even welded on?))). Even the wire sometimes fenced off !!! (And this happens with prolonged stress and poor contact). A magnet can not be heated above 80, it seems degrees !!! (I can not vouch for the accuracy of the numbers, the Curie point for different materials is different, but if it becomes very hot - in any case, it will cease to be a magnet!). And given the already voiced above, weak pressing, even on a flat and cleaned surface, such a mass will necessarily heat up with prolonged holding of the arc. Accordingly - for the "tack" it is suitable. But then - you need to change to a regular crocodile!
In fact, it is needed only where you have to cook a huge sheet, to the edge of which the wires are not reached !!! And it is necessary precisely in order to be able to weld the pin and catch on a normal crocodile, or a clamp! (For this purpose, such masses purchased are positioned, and not for permanent work.) And this is despite the fact that the mangit used there is not just any, but from a ferromagnet with the highest Curie point ...
Ordinary mass is made either in the form of clothespins or clamps whose clamping force is much greater than the magnet's attractive force. In addition, contact occurs on both sides, and it will definitely be on some side, since the teeth of the clothespin or the clamp bolt will necessarily tear off paint or rust, and the magnet lies on only one plane.
Well, the usual mass? It can’t be rusty either, paint can’t. Moreover, you can’t attach a clamp everywhere.
As I wrote recently under a similar product - it's pampering!)))
The scope is very limited. On rusty - it is impossible. On paint (its remains) - it is impossible. On dirty - it is impossible, on round (pipe, pin) - it is impossible ... To cook a continuous seam - it is impossible (only for tacks) ...
It turns out a mass that can only be used on a plane of brushed metal and only for tacks ...
Question: why the hell is such a mass ???
