Welding device

The innovation relates to a welding device to facilitate and improve the welding of all commercially available iron and non-iron profiles and for performing miter and butt welds according to various known welding processes,

7441938 06/26/75

such as electrical, fusion, deposition, gas fusion and arc welding.

There are already welding devices known, which consist of two perpendicular to each other, Contact surfaces firmly connected to one another by a bar as a handle with the angular center left open consist of permanent magnets at intervals

for holding the workpieces to be welded iso

are embedded. These devices, in which the web between the two contact surfaces in the Angle range of 90 is arranged, are particularly suitable for welding internal angles, are but because of the special arrangement of the web, it is extremely unsuitable for welding Λ'οη external angles.

In order to be able to weld outside angles with a device of the type mentioned, the is used as a handle serving web newly designed arcuate and arranged so that he the two at right angles connects mutually standing contact surfaces on the outside in the angled area of 270 °, In this way, the interior of the two contact surfaces remains completely free ·· .. ·

Below is the innovation based on the drawing, in a preferred embodiment of the subject the innovation is shown, explained in more detail. Show it:

Fig. 1 shows a device according to the innovation in

Side view,

Fig. 2 shows the same device in a front view and

3 shows the device in use, for example when welding an external angle or connection of two metal sheets at right angles.

The device with the web 1 and the contact surfaces 2, 3 is expediently cast in one piece from cast iron. The two contact surfaces 2, 3 are at right angles to each other and the arched web 1 serving as a handle bridges the two contact surfaces 2, 3 on the outside. Depending on the size of the welding device, there are several round ones in the contact surfaces 2, 3 Permanent magnets 4 embedded, which are secured against the surrounding metal by means of non-magnetic material, e.g. B. plastic rings 5> are isolated.

The welding devices are designed according to the size or length of the object to be welded Number with the for easy mobility of the

Welding torch and accessibility of the weld seam required gaps on the horizontally lying one Profile, sheet metal or the like. Put on and then the workpiece to be welded or welded to the vertical Contact surface 3 applied and held there reliably by the action of the permanent magnets 4. The welding bead 6 can be unhindered by the welding torch 7 through the opening 8 between the two contact surfaces 2 and 3 and the free space 9 in the web 1 can be passed through. The welder has both hands available exclusively for the welding work, the se can be completed without interruption and additional facilities.

The welding device according to the innovation is natural

mainly intended for welding magnetic materials.

With non-magnetic materials (aluminum, plastic etc.) the device is used to weigh down the lower, horizontally lying workpiece, while the Workpiece to be welded on or on using clamps or other suitable fastening means, is held on the vertical contact surface 3.
