Thick basic-covered electrode for depositing highly wear resistant overlays. The weld metal can only be machined using sintered hard metal tipped tools. It is particularly resistant to impact and shock. A tough buffer layer (with 1803J electrodes) is only required with crack sensitive steels. It is possible to deposit even a large number of layers without the need of intermediate buffer layers. 1622V can be easily welded in all positions expect vertical-down.
