CPC classification number: B23K20/12
Abstract: This invention provides a method for underwater frictional welding of metallic articles, which method comprises preparatorily wrapping a heat insulating material such as tape around the periphery at the terminal face of each of the metallic articles subjected to welding, abutting under pressure the terminal faces of the metallic articles against each other and welding the confronting ends of the metallic articles by utilizing the frictional heat produced in the terminal faces by the relative rotary motion and the pressure exerted in the axial direction.
