Welding small-sized, single-pass welds typically causes a high amount of base metal dilution; a large amount of base metal is melted and mixed with the weld metal. As a result, the weld picks up a sizable amount of alloying elements from the weathering steel, which can provide the weld metal with the same atmospheric corrosion resistant properties as the base metal itself.

Slewing ring bearings, turntable bearings | Kaydon …
The DT series consists of the eight-point ball bearing that Kaydon originally developed to provide maximum load capacity for given envelope and bolt circle diameters. It provides an up to 80% increase in capacity over that of a single row four-point design, yet has a smaller profile than a three-row roller design and provides exceptional moment, thrust, and radial load capacities.
