Bevelling and orbital welding processes |PARCITANK, S.A.|

Bevelling and orbital welding processes are used in a variety of industrial applications to ensure the integrity and durability of the structures and systems being assembled. At Parcitank, these processes and techniques play a crucial role in the manufacturing phase, ensuring the functionality, safety and longevity of your product.

- SCH Pipe Bevelling: SCH (Schedule) pipe bevelling is a fundamental technique for preparing parts prior to welding. This process involves the removal of a portion of the pipe edge, creating a sloped or bevelled shape that facilitates the joining of two pieces effectively.

- Open Head Orbital Welding: Orbital welding is an automated method of welding that uses a rotating head to perform the weld in a circular motion around the workpiece. The use of an open head in this process allows easier and more efficient access to the weld zone.

- Closed Head Orbital Welding: Unlike the open head, the closed head provides complete coverage around the weld joint. This type of head protects the weld area from the external environment, which is particularly useful in harsh conditions or when a controlled atmosphere is required, such as when welding sensitive materials or in environments where there is a risk of contamination.

- Root Pass and Filler: In pipe welding, the root pass is the first weld pass made at the joint of the parts. Its main function is to ensure full penetration into the root of the joint and to form a solid base for the subsequent weld layers.

Once the root pass is completed, the filler weld proceeds. This step involves the addition of additional weld material to completely fill the joint and provide adequate mechanical strength.
