Our Plate Bevelling Service
Removing material from the fringe of a steel plate leaves behind a space for your welding material to fill. This edge is what is known as a bevelled edge. This allows suitable penetration and deposition of the weld, providing the opportunity to establish a more robust joint.
When butt welding material that is 10mm or more, you may often find that you require some form of edge preparation before the welding begins.
What other joint configurations can require edge bevelling?
There are many joint configurations that may require edge bevelling, that include:
- T joints
- Corner joints
- Lap joints
- Edge joints
- Mechanical bevelling
- Skew Head
The three types of Sheet Metal Bending
Air Bending
This process works by pressing a punch onto the workpiece and forcing it down into a bottom V-shaped die. This die is mounted onto the press. The punch creates the bend so that the space between the side wall of the V and the punch is larger than the thickness of the workpiece. As this process requires less bend force, it tends to use smaller tools than other techniques. Air bending is extremely flexible, allowing a number of different materials and thicknesses to be bent in variable angles. This process also requires fewer tool changes than other methods, meaning higher productivity.
Bottoming
This technique, sheet metal is forced against the V opening within the bottom tool. A set amount of space is left between the bottom of the V opening and the workpiece. This method offers more precision and less springback, but a different tool set will be required for every different material, bend angle and thickness.
Coining
In the coining process the top tool forces the material down into the bottom die with 5-30 times the amount of power of air bending. This causes perpetual deformation through the workpiece and there is very little springback, if any at all. This method offers high levels of accuracy.
