AI Technical Summary
Existing welding methods for stainless steel linings in offshore structures cause thermal deformation and plate lifting, leading to potential melt-off and require time-consuming fine-pitch tack welding to prevent this.
A laser welding method is employed to join thin stainless steel sheets to carbon steel or stainless steel substrates, optimizing heat input and reducing thermal deformation by using a guide member and minimizing the use of welding materials.
The method effectively suppresses burn-through and ensures corrosion resistance of the welded joint while reducing costs and time by minimizing heat input and eliminating the need for extensive edge alignment.
