WELDING
in finishing
Spot Welding Operating Principle
Spot welding is based on a thermoelectric process that combines pressure and electric current to join two or more metal pieces. The main steps of the process are detailed below:
1 Pressure Application: The electrodes, usually made of copper or high-conductivity alloys, exert controlled pressure on the pieces to be welded. This pressure ensures proper contact between surfaces and reduces electrical resistance outside the desired zone.
2 Electric Current Flow: Once the electrodes are in position, a high-intensity electric current is applied for a short period. The natural electrical resistance at the contact point generates localized heat that raises the temperature to the material’s melting point.
3 Fusion and Welding: The generated heat melts the contact surfaces, forming a small molten area (weld nugget) that unifies the pieces.
4 Current Interruption: Once the desired fusion is achieved, the current supply is cut. At this stage, the molten material begins to cool and solidify, forming a strong and inseparable bond.
5 Pressure Maintenance During Cooling: It is crucial that the electrodes maintain constant pressure while the material solidifies. This prevents the formation of pores or internal cracks, ensuring a robust and high-quality weld.
In summary, the combination of precise pressure and controlled heating allows for a reliable and uniform bond, ideal for demanding industrial applications.

CUTTING:
3000 width
THICKNESS:
10 mm max thickness.
Shearing for thin materials is an essential cutting service in the metallurgical industry, offering fast, precise, and cost-effective cuts. This method is particularly useful for high-volume production that does not require the complexity of other cutting processes.
Shearing employs a blade system to make straight cuts in metal materials. Unlike other methods, such as laser or plasma cutting, shearing is quick, efficient, and economical for simple straight cuts.
FEATURES:
> High precision: Shearing delivers clean, precise cuts with minimal burrs, reducing the need for additional finishing.
> High-volume cutting capability: Ideal for mass production, enabling rapid and efficient cutting of multiple pieces.
> Material versatility: Capable of cutting various metals, including:
Carbon Steel, Stainless Steel, Aluminum, Brass, and Copper.
> No heat input: As a mechanical cutting process, shearing does not generate heat in the cutting zone, preventing thermal deformation of the material.
FLATTENING
