Greetings to all novice metal lovers! For our household welding with an inverter, you can sometimes use an interesting method of joining metal, which is called electric rivets.
In general, this welding technology was used in the USSR in car building. Specifically, the carcass was sheathed with thin sheet metal using electric rivets. The method is simple and productive. But for a garage house, it is also quite suitable. See what it is.
Here we need to weld thin sheet metal to the base from a profile pipe or corner. In places where the sheet will adhere to the base, we drill holes and weld through them.
It turns out such a weld point in the shape of a mushroom! You don't even need to drill holes, but simply burn through the sheet metal with an electrode and immediately weld it to the base metal. But here it is a little more complicated in terms of welding skills.
This will be the welding connection with electric rivets. It is also called a cork seam in production. Welding is quite reliable, does not deform the sheet metal so much.
It is also good to weld sheet metal with an overlap with an electric rivet. We also drilled the top sheet and welded to the bottom through these holes. Well, or immediately burn and weld.
The welded mushroom bulge itself can be sanded flush with the base. Then the connection will not only be strong, but also the welding spots after priming and painting will not be visible. Plus, there is practically no deformation of such a connection.
You can weld doors, gates, sides for a light trailer or walk-behind tractor with your inverter at home or in a garage. Any joints where there is a frame to which thin sheet metal needs to be welded.
Rivets for joining have been made for a very long time. Then there was no trace of welding. But the blacksmiths heated the metal blank rods and connected two pieces of metal with them.
So take into your arsenal of technical knowledge such a simple, but quite working and reliable method of welding in our everyday conditions. I hope in the comments people will share with newbies that they also sometimes use the electric rivet method in their welding.
