Abstract: A method is disclosed for lining a bearing shell with a babbitt metal which does not require tinning of the bearing shell and does not require premelting of the babbitt metal. An inner cylindrical surface of a bearing shell is covered with a flux and lined with a solid babbitt metal. The shell and babbitt metal are rotated about a horizontal axis coaxial with the cylindrical axis of the shell at a rotational velocity sufficient to generate an acceleration at the radially inner surface of said shell of about 20 g's. The babbitt metal and flux are heated to a temperature sufficient to melt the babbitt and the flux and metallic oxides and other impurities at the interface of the babbitt metal and bearing shell are urged toward the axis of rotation permitting a strong metallurgical bond between the babbitt and bearing shell. The shell is cooled and the impurities are machined from the radially inner surface of the babbitt metal.

Abstract: A method and apparatus for producing electroslag T-joints where fillets are required is provided by utilizing a water-cooled copper shoe with a slag relief notch placed along the weld joints to provide a dam for the fillet material; the location of the slag relief notch in the shoes of various radii is determined according to a precise formula which provides the required results.
