Resistance welding machines of the UV/UVL series are more powerful machines than machines with a radial stroke of the upper electrode of the UVS series. They are equipped with a more powerful pneumatic or electromagnetic drive for compressing the electrodes, and have high welding currents. These machines, like UVS (radial), are equipped with autonomous liquid-cooled electrodes.
The movable electrode moves linearly, therefore the alignment of the electrodes and the parallelism of their ends are preserved. This ensures uniformity of welding over the area. Thanks to this, it is possible to perform operations inaccessible for radial machines - for example, high-quality welding of nuts to a flat sheet, allows welding with wide electrodes, projection welding, etc.
The machine is equipped with a microprocessor control system with quick and convenient setting of welding parameters, with storing 10 welding programs.
The machines are capable of performing various tasks for resistance welding of sheet metal products, profiles, wires and fittings in industrial enterprises, in conditions of intensive production. Contact welding machines UVL can be of interest to both large and small businesses.
UV/UVL machines are designed for welding parts from
- stainless steel, low-carbon steels with a thickness of 0.3 + 0.3 to 6 + 6 mm,
- galvanized steel, titanium alloys with a thickness of 0.3 + 0.3 to 2 + 2 mm,
-aluminum and alloys up to 2 + 2 thickness
- sheet copper up to 1 + 1 mm thick.
- cross-shaped connections of reinforcement up to 18 + 18 mm
The machine configuration depends on the thickness and dimensions of the parts to be welded:
sticking out of electrodes: from 300 to 750 mm
maximum welding current: 12 to 26 kA
compression force: 75 to 600 kg
It is possible to manufacture a machine with a special shape and configuration of electrodes, for example, for welding a pipe made of sheet metal with a diameter of 75 mm and a length of up to 1.5 m, for projection welding, for welding several points at the same time, a fast modification - up to 300 welds / min. (For example , to simulate seam welding), etc.
