Impermeable seams guaranteed; during roller-seam welding

The most important thing during roller-seam welding is that the seam is absolutely impermeable. And that is exactly what our high-performance machines guarantee. Because, we always produce for you at the highest level of quality and according to your requirements. And we accomplish that on short notice and at attractive prices. How is that possible? Simple: We manufacture your roller-seam welding machine based on the modular system that includes a large number of components and a comprehensive accessory range. We manufacture nearly all individual parts and above all the transformer, the core-component of every welding machine, ourselves, which ensures that they meet the highest demands and are always in stock. The exact appearance of your machine depends on your individual needs. We will gladly also take concrete specifications, for instance regarding pneumatics, controller or color, into account. After all, your requirements for roller-seam welding is what drives us.

The seam (roll) welding special machine is the evolution of spot welder. It uses the roller electrode to replace the cylindrical electrode of spot welding and as the welding work piece moves between the rolling plates, the seal welding will generate weld nuggets which will overlap with each other so as to achieve welding effect.

AC pulse current or even better DC Medium Frequency will be adopted. Roll welding is widely applied to light gauge welding of sealed container of oil drum, can, heating radiator, airplane and fuel tank, rocket and missile.
