Definition - What does Lamination Seam mean?
A lamination seam is part of a weld seam inspection in which the weld seam is overlayed with the lamination material to produce a smooth finish on the weld seam. A lamination seam can protect the weld portion on a metal joint from corrosion.
Corrosionpedia explains Lamination Seam
The purpose of laminating a weld seam is to make it rigid so that the weld portion on the metal remains intact and the finish remains smooth, shiny and corrosion free.
Benefits of a lamination seam:
- Protects the weld portion on the metal joints from corrosion.
- Protects the inner portion of weld seam joints from internal corrosion.
- Ensures the coating remains intact and in place.
- Ensures efficient bonding of paint to the metal structure.
- Enhances the bonding strength.
Weld seam inspections are a test technique to determine if any flaws exist in a welded joint. The weld seam inspection also checks the external appearance of a weld seam to evaluate the quality of a welded joint. A weld seam inspection is a non-destructive test (NDT) technique. Weld seam inspection is also known as weld seam testing.
