We use several different techniques when we cut metal plate. They are:
- Gas cutting
- Plasma/fine-plasma cutting
- Bevel cutting
Gas cutting is effective for plates over 60 mm thick
A highly effective method for cutting plates over 60 mm thick. We can cut 300 mm without a problem; no other technique cuts plate as thick. The high temperatures that develop mean that in some cases the plate’s properties may change; this is known as the HAZ (Heat Affected Zone). To counter this, we apply gas cutting under water on some materials. The plate is cut under water, which reduces the negative changes in the plate’s properties. Our machines for gas cutting work with up to eight burners simultaneously, resulting in highly efficient production.
Plasma/fine-plasma cutting for less heat impact
For plates up to 50 mm thick, fine-plasma cutting is effective. Cutting with plasma is faster than with gas, which means less heat impact. The HAZ is, therefore, not as large and the changes in the plate are smaller. We have cutting tables that allow multiple plates to be laid out for plasma cutting. So while one plate is being cut, details can be picked off and the next plate prepared for cutting. This facilitates continuous, efficient operation.
Bevel cutting prepares for welding
With bevel cutting we cut and bevel the plate at the same time using fine plasma. We prepare joints (such as y and k joints) so the plate is ready for welding. In some cases the finished product is sent direct to the customer. Small or large, it doesn’t matter. You do the drawings, we bevel plate up to 40 mm thick.
