I greet all the guests a channel, especially subscribers continue to make useful articles for everyone who has decided to develop a manual arc welding alone.
Today I want to show you the way to the welding flaps Garage door with plug. Briefly, elektrozaklopka is a welding method, when the metal sheet is connected with the base frame of the welding point, in one case, electrode sheet metal is melted and welded with its base, and the other drilled holes in sheet metal, and after they are welded with its base. The method is used for welding of large-sized products.
I cooked in the garage door last week. Their dimensions are 3000 to 2250mm. The box was welded from 75 corner, and themselves gate wings made of proftruby 40 to 20, 2mm thick.
Gate leaves I put together and welded single-piece construction, which after full obvarki cut in the middle to divide a single structure by 2 folds.
The next stage of the sheet metal has been exhibiting in the required position so that it overlaps the very gates of the box around the perimeter of the 10 mm.
Then take marker cord with chalk, and repel on the sheet metal (incidentally he 2mm) lines that are strictly middle profile tubes carcass gate valves.
Then take a marker and a ruler, and on these lines mark places of drilling. I have them mark up through 150 mm, the drill will use 8 mm in diameter, this would be enough for our purposes.
Remove the marked sheet with a frame, but do not forget to pre-draw the boundaries of the box in which lay a sheet, then to return it to the desired location. Drills for marking and we clean the opposite side of the grinder burrs after drilling.
On lronburg unnecessary and trimming sheet metal select the optimum welding current experimentally. The photo shows that welding elektrozaklopkoy provides a tight connection and a minimum deformation of the welded metal parts.
We place a sheet of metal back into the boundary marks on the box, and starting from the middle of the sheet through the openings welding, fusing proftrubu and sheet metal. Do not forget that with this method you need to press the most densely welded parts. I for this purpose have a homemade clamp (The photo shows its simple design), the way the channel has A separate article about this video clamp, who are interested, and hearken to the flip design, the thing irreplaceable.
Do the same thing with the second sheet, mark up, drill, weld.
With such dimensions of the gate leaves, we will not get one sheet per leaf, and so we have to make the insertion of the narrow metal strips, which we also welded to the frame elektrozaklopkami.
We clean fungi elektrozaklopok sanding disc, and then another pass petal disc to sanding seats were perfectly smooth. That's all the leaf protection net. Deformation in this method is much less than if the weld short shovchik from the carcass. But with this method will be more, but it's worth it.
