Surfacing Deposition Sequence
The surfacing weld sequence specifies the order in which layers and beads are placed to avoid dilution and minimize cracks.
Physical-Chemical Mechanism of Action
The surfacing weld sequence influences the diffusion rate of elements through the material lattice. An incorrect sequence can lead to uneven distribution of chemical components, which can cause dilution and possibly cracks in the surfacing material.
Metallurgical Relevance & Risks in Welding
A wrong sequence can lead to uneven dilution of elements and the formation of cracks in the surfacing material. This can impair the strength and mechanical integrity of the weld, posing risks to the safety and service life of the component.
Workshop Practice & Instructions
Always follow the specified surfacing weld sequence in the technical drawings. Place the layers and beads in the prescribed order to ensure even distribution of elements. If in doubt about the correct sequence, always consult the material handbook or contact the client.
