Our common processes are:
Electrode welding is the most flexible type and it's based on the electrode melting due to the energy of an arc drawn between the electrode and the work piece. Electrode are metal conductor sticks made by different material based on the operation type. The stick is covered by antioxidant material. When the electrode, that is fixed by an holder, is close to the piece the electric arc starts. This arc cause the electrode and the work piece melting. The welder moves manually the electrode holder. After the welding it's necessary to remove the slag that cover the welding and that is usefull to defend the metal during the cooling.
We use this kind of welding especially outside the workshop. Otherwise this technique is used as "first welding step"; than the welding is completed with TIG.
Our welding procedures (WPQR) are certified according to the UNI EN ISO 15614-1 norm. Our welders are certified in accordance with UNI EN 287-1 qualified by the notified body Vincotte.
These processes use the heat transferred by an highly ionized gas (plasma) or by oxy-acetylene flame and a jet of pure oxygen to bring the steel to the melting temperature and thus to break the continuity of the metal. In this way we can cut the sheets in our workshop by automatic pantographs. To cut sheet metal on the field instead we have 3 mobile modules.
Bending is a mechanical process through which it is possible to deform a particular object by sticking forces. Through a bending machine in our workshop we can bend sheet metal of different thickness to create semi-finished or finished products according to customer specifications.
This plastic deformation process can transform the sheet metal with our machines (calenders). These machines are equipped with three or four parallel axes steel rollers with adjustable distance. The rollers rotating at low speed, following a circular trajectory, give the appropriate curvature radius to the sheet. We can thus obtain conical or cylindrical shapes depending on the type of processing required.
