The welding method is typically used for geometries with large wall thickness differences which prevents an even cooling from the back of the body to the bonding zone.
Welding techniques for the coating with babbitt metals are typically used in the case of non-uniform wall thickness of the backing material. In these case, a directed cooling from back side of the backing body towards the babbitted surface is not possible, thus having a negative effect on bond.
Finally, it is suitable for base bodies of virtually any size and geometry. For the actual operation of the area to be coated of the body is aligned horizontally. The edges of the area to be coated are sealed with appropriately made frames or sheets and suitable sealing material. We use bearing metals in triangular or square profile form as rod material as welding material. After reaching the prescribed body temperature, the actual welding process begins on one side and should be done quickly over the entire body width.
