Piercing Piercing is the process of creating a hole or starting point in a material to initiate plasma cutting or welding operations. In plasma cutting, piercing involves directing the plasma arc onto the surface of the workpiece until it melts through the material and forms a hole. Piercing is commonly used to start cutting operations on thick or heavy materials where the plasma arc cannot penetrate directly.
It requires precise control of the plasma torch's position, angle, and power settings to create clean, round holes without damaging the surrounding material. Piercing is a critical step in plasma cutting processes, enabling efficient and accurate cutting of various materials with minimal downtime and material waste. |
